2. 1, unify thinking, recognize the significance of energy saving and emission reduction, strengthen the concept of cost, and form a new situation of energy saving and consumption reduction and tapping the potential of all employees.

Saving resources is a basic national policy of our country, and energy saving and emission reduction is the common responsibility of the company's cadres and workers. Thought is the forerunner and knowledge is the premise. In view of the misconception that "big development means big spending" and the phenomenon of extravagance and waste in the minds of some employees, the company has held special meetings for many times to study and formulate the work plan of energy conservation and emission reduction, made full use of radio, television, after-school meetings and other forms to strengthen publicity and education, enhance resource awareness and conservation awareness, and strive to create a good atmosphere for all employees to save energy and emission reduction, so as to make energy conservation and emission reduction become the consciousness of all employees. In the company, we vigorously advocate the wind of "advocating thrift and opposing waste", carry out in-depth discussion activities of "reducing costs and improving coal quality", educate and guide all mine workers to firmly establish the idea of "working hard and running the mine diligently", enhance their sense of urgency and responsibility, and form a strong atmosphere of "glorious energy saving and emission reduction, shameful extravagance and waste" in the whole mine, so that energy saving and emission reduction will become the knowledge of all mine workers.

In order to further enhance the sense of responsibility for this work and fully mobilize the enthusiasm of all employees, the company has specially formulated and issued more than 0 documents 10, such as "Appraisal Measures for Innovation Management of Jingting Industrial Company", "Appraisal Measures for Internal Contracting of Enterprises" and "Implementation Opinions on Saving Expenditure and Tapping Potential Internally", and assessed the work requirements, working groups, processes, rewards and punishments and innovative projects of safety technology management.

At the same time, the company strengthens the concept of cost and forms a comprehensive cost management model. Since the beginning of this year, the company has focused on strengthening the concept of cost in the whole mine. Through training, publicity and other educational means and index decomposition, the employees can truly realize the extreme importance of cost work, make it clear that the ultimate goal of enterprise management is to reduce costs and maximize benefits, let every employee establish the consciousness of efficiency first, reduce consumption and increase efficiency, and effectively mobilize the enthusiasm and initiative of all employees.

2.2 Digging for the source and adopting "three steps" to reduce costs.

2.2. 1, optimize the roadway design, strictly control the roadway section, and implement the "three-five-three" assessment mode. For production mines, the highlight of energy saving and emission reduction work is underground, and the focus of underground mine begins with roadway design and construction. To this end, the mine specially formulated and issued the "Implementation Opinions on Strengthening the Management of Mine Design and Construction".

2.2. 1. 1 In terms of roadway design, three principles should be adhered to: First, the roadway horizon design can be arranged along the coal seam, not in the whole rock, but in the whole rock, and the construction should be carried out in the stable rock stratum as far as possible. Second, the roadway section design should meet the relevant requirements of safety regulations, meet the needs of ventilation, and fully consider the import and export of large mechanical and electrical equipment. The shape of the roadway is (inclined) trapezoid for the roadway built along the coal seam, and arch section for the roadway in the rock stratum. In order to ensure that the roadway can be used normally after being deformed by dynamic pressure, the reserved section of the roadway is designed as 100 ~ 200 mm for the roadway affected by dynamic pressure. Thirdly, the design principle of roadway support, design roadway support mode according to roadway lithology, and select support parameters according to roadway service life. The design principles of integral support are: bare bolting and shotcreting, bolting and shotcreting without hanging net and scaffolding hanging net. The above three principles ensure the maximum work efficiency with the lowest input.

2.2. 1.2 in mine construction, adhere to the "five no payment". First, the construction team does not pay for the excavation of the waist line given in the production design, and does not pay for the "opening the door" without authorization. Second, if the location, length and width of the temporary parking lot can be constructed without the research and notice of the production technology department, no fees will be paid. Third, if all kinds of equipment rooms and safe rooms are not built according to regulations, there is no charge. Fourth, if the construction team fails to stop the excavation according to the regulations after receiving the notice of shutdown issued by the production department, it will not pay the excess fee. Fifth, in the construction process, the support method was not strictly in accordance with the provisions, and the support method was changed without authorization, and the support cost was not paid.

2.2. 1.3 in the assessment and settlement of mine engineering, we should adhere to the "three non-settlements". The production department, the wage department and the enterprise management department set up a quality assessment and acceptance team, and organized the acceptance once every ten days. First, the quality acceptance of mine engineering is evaluated by percentage system, and on-site grading is carried out according to the quality standard acceptance list. Above 95 points is excellent (excluding 95 points), 90-95 points are qualified, and below 90 points are unqualified. Unqualified project quality will not be settled. The second is to settle the roadway with excellent products according to normal standards; 20% of wages and material costs will be deducted from the roadway that has passed the acceptance; For unqualified roadway, the tasks of footage, salary and material fee will not be settled. The third is to assess the three members of the district team, and each of the three members of the construction unit who have achieved excellent products will be rewarded with 1000 yuan, and each of the three members of the construction unit whose products are unqualified will be fined with 1000 yuan, which will be rectified within a time limit, and the expenses will not be settled during the rectification period.

By implementing the "3-5-3" assessment mode, popularizing the medium-long hole blasting technology and adopting small-section construction, the cycle time of each operation is reduced, the consumption of linear materials is reduced, and the single advancing level of whole rock excavation is improved. For example, when the No.34-1track goes up the mountain, the roadway section changes from the original net section of 5. 14m2 to 4.32m2, the material consumption per meter is reduced by 40.8 yuan, and the single-entry horizontal work efficiency is improved by more than 30%.

2.2.2 Do small things, improve big things and strengthen power saving. Electricity expenditure has long been the bulk of enterprise production costs. Combined with its own reality, the mine has implemented five energy-saving measures.

2.2.2. 1 Replace the energy-saving lamp. All incandescent lamps used for ground lighting in the whole mine are replaced with low-power energy-saving lamps, and all redundant lamps are removed. Acousto-optic controller is used for corridor lighting to save electricity. According to incomplete statistics, before the replacement, the total number of incandescent lamps in the whole mine was 4000, with a total power of 240kw；; The total number of energy-saving lamps after replacement is 3,500, with a total power of 70kw, which is more energy-saving than before replacement 170kw. According to the calculation of 3 hours of bright light every day, the annual power saving can reach more than 654.38+10,000 yuan. The underground roadway lighting is replaced by energy-saving lamps for line and external monitoring, which automatically controls the start and stop of lights and reduces the time of ever-burning lamps. In addition, we also pay great attention to saving electricity in some subtle places. For example, the four site lights in the coal preparation plant used to turn on 12 hours a day on average, but now they have all been removed and stopped. In production, corner lighting of workshops and corridors can meet the requirements. After calculation, it is estimated that the capital investment of energy-saving lamps can be recovered in 9 months.

2.2.2.2 saves electricity and reduces the consumption of logistics services. Employees' domestic water, pump room pump motor frequency conversion control, use water tower to supply water regularly to participate in load adjustment, and strictly control the pump start-up time. For example, the power of a drinking well pump is 75KW, and that of another pump is 37KW, with an average of10.5h per day, which shortens the pumping time by 6 hours per day on the original basis. In this way, the two pumps can save about 34,000 yuan of electricity every year.

2.2.2.3 speeds up the technological transformation of energy-saving production equipment. Centralized air supply is adopted for the mining head, and the running time of the air compressor is controlled, which saves the time of starting the air compressor for 2 hours every day, and saves about 2 1 10,000 yuan of electricity fee every year. After the energy-saving renovation of the drainage system, a static pressure tank is built at -20 places, and the coal washing water is directly supplied to the coal washing plant by multistage pumps for drainage, which can save 65,000 yuan of electricity fee every year compared with-105 pump room water supply.

2.2.2.4 optimizes its transportation system to save electricity. Start mode along coal flow is mainly adopted. In the original coal mining face, when transporting coal, the valve and belt are opened at the same time. When there is no coal, the valve belt appears no-load phenomenon, which causes waste of electric energy. After the transformation, the coal in the coal mining face starts along the coal flow, that is, when the coal is discharged from the working face, the valve of the working face is opened first, when the coal is 50 meters away from the nose, the next valve or belt is opened, and when the belt or valve is empty 10 minute, the belt and valve are stopped, so as to achieve the purpose of saving electricity. When two working faces * * * use transport belts, coordinate the coal unloading time of the two working faces, and adopt centralized coal unloading mode to reduce the running time of the belt. According to the calculation of saving 2 hours of no-load running time every day, the electricity bill can be saved by 360 thousand yuan every year. At the same time, the electrical control system of winch has been reformed, from the original PKJ control panel to PLC frequency conversion control, which can save about 80 thousand yuan per year; Dry-type transformers and other high-energy electrical equipment have been replaced. Compared with the original oil-immersed transformer, the transformer loss is reduced by 2%, and the annual electricity bill can be saved by about 456,000 yuan. In addition, the start-stop system of overhead passenger ropeway is implemented, and the working system of stopping for 4 hours every day is strictly implemented, which can save about 60 thousand yuan of electricity every year.

2.2.2.5 has installed low-voltage reactive power local compensation device to save electricity. Through investigation, the reactive power compensation of the main exhaust fan is automatically tracked and the high voltage reactive power of the ground substation is automatically compensated, which improves the overall power supply quality and stability of the power supply system in the mine, and the annual power saving cost can reach 654.38+0.26 million yuan.

Through the implementation of the above energy-saving measures, the annual electricity bill can be saved by about 6.5438+0.6 million yuan.

2.2.3 Tap the potential, reduce consumption, and strive to reduce production costs. In order to build an energy-saving enterprise and improve the economic benefit of the enterprise, the mine implemented the target management measures of reducing the material consumption 10% in the mining area and 20% in the driving area.

2.2.3. 1 Strictly control the use and consumption of large materials. For belts, wire ropes, tracks, steel pipes, etc. used underground, the service life of these large materials should be extended as much as possible by strengthening management, and all the large materials withdrawn from the mining head should be recycled. This alone saves nearly100t of track, belt1700m, wire rope15t and steel pipe10t every year, saving a total value of nearly 800,000 yuan.

2.2.3.2 optimized the blasting parameters and reduced the consumption of blasting materials as much as possible. In order to reduce the consumption of blasting materials, the mine set up a blasting test team to re-optimize the blasting parameters of the original design of the coal mining face. At the same time, strictly implement the optimized blasting parameters and charge after the test, and achieve the best blasting effect with the minimum charge, thus improving the unit yield level of the working face. For example, in the coal mining face, after a lot of experimental analysis and comparison, reasonable blasting parameters are selected, and the circulating footage is increased from the original 0.9-1.0m to1.9-1.0m under the condition that the total charge is unchanged and the eye distance is increased; At the same time, it reduces the material consumption, improves the working efficiency and increases the circulating output of the working face. Take a working face as an example: the length of the working face is 120m, and the average coal thickness is1.0m. The original explosive consumption is 90kg, but the detonator consumption is 240 rounds; The explosive dosage was reduced to 82kg, and the detonator dosage was reduced to 2 18 rounds; The total consumption of original explosives and detonators per ton of coal is 5.05 yuan/ton; Reduce the total consumption of detonators per ton of coal explosives to 4. 1 yuan/ton. In this way, the cost per ton of coal is correspondingly reduced by 0.95 yuan/ton.

2.2.3.3 strengthens material management of drill bit, drill pipe and three-way valve. In order to make full use of downhole drill bits and drill pipes, the mine strictly implements the old-for-new system. The district team must provide 95% old parts for new drill bits and drill pipes from the supply department, otherwise the supply department will not handle them. The old bit recovered by the district team is handed over to the mechanical and electrical department for treatment and utilization. The district team must hand in the damaged three-purpose valve in time, and shall not hand in the old valve or issue a new valve. The instrument factory should establish a ledger, and the repaired three-purpose valve can only be used by the original unit. Under special circumstances, it must be approved by the vice president of production. Through the implementation of the above measures, the production cost is greatly reduced by starting from small things, starting from subtle points, and grasping management and saving from bit by bit.

2.2.3.4 vigorously develops recycling activities. The mine actively advocates the business philosophy of "saving is earning" and "saving is earning", and actively carries out activities of double increase and double festival through various effective forms. The recycling system of waste materials and the ledger of waste materials were established. It is required that all teams in each district must set up material recycling boxes in their workplaces, and the recycled materials should be placed centrally according to different materials, so as not to waste a screw or a spike. There are four large-scale recycling stations for waste materials underground, which mainly recycle large-scale equipment and materials. Encourage underground units to purchase, and reward all small materials that can be used in the recovery well at 20% of the original value.

2.3. Give full play to resource advantages and create potential benefits.

2.3. 1 adjust measures to local conditions, give full play to the advantages of water resources and use them underground.

At present, the mine water inflow of Jingting Industrial Company is about 530m3/h, which is mainly goaf water and aquifer water with good water quality. In order to reduce mine drainage, some mined-out areas and aquifer water are comprehensively used as mine production and dust-proof water, without mechanical equipment for water supply, which saves equipment investment, labor costs, power consumption and maintenance costs, not only reduces mine production costs, but also achieves the purpose of energy saving and emission reduction. The mine uses four underground water sources to form two water supply systems. The first system uses the pressure generated by the ground pressure of the water source itself to supply water to the mining head. The total water supply flow is1100m3/h, and the water supply pressure is 7.2Mpa (three ash water pressure). It is the main water supply source for mine production and dust prevention. The second water supply system uses the pressure generated by the horizontal drop to supply water to the horizontal working face, and makes full use of the old empty water in the upper goaf of the working face as the auxiliary water source of the mine.

In addition, a static pressure pool was established at the level of -20, and the lower landscape was introduced into the reservoir. Part of this water is used to repair the dust-proof water in -20 roadway excavation, and the other part is discharged to the ground coal washing plant as coal washing water through multistage pumps, thus realizing the recycling of water resources.

Through the comprehensive utilization of mine water, the annual cost savings reached1109,000 yuan.

2.3.2 Highlight the benefit project and focus on the transformation and utilization of raw coal bunker. The transformation and utilization of raw coal bunker is another economic growth point for industrial enterprises to save energy and reduce consumption. In recent years, this mine mainly mines 16 coal seam. As we all know, 16 coal seam is a big problem because of its high adhesion index and high viscosity. In order to make better use of raw coal bunker, the mine actively tackled key problems and explored this topic, and went to the design institute for experts to optimize design guidance many times. After many investigations, we decided to turn the advantages of existing resources into benefit projects. The mine invested more than 200,000 yuan to complete the transformation project. Since it was put into operation, the effect is very good, and the long-term economic benefits produced by one-time investment are very considerable. In the past, forklifts were used to load coal in mines. Based on 280,000 tons of coal per year, the annual consumption of diesel oil is 474 1 1kg, which is about166,000 yuan when converted into 3.5 yuan /kg. After transformation and use, the raw coal bunker can store 350 tons of coal. According to the calculation of putting 1 coal bunker every day, 2 1440kg of diesel oil can be saved every year, and the planned price of diesel oil is 4.00 yuan /kg, which can save more than 86 thousand yuan every year. At the same time, it also reduces the wear and maintenance costs of forklift trucks, saving more than 20,000 yuan per year and generating a total economic benefit of about 654.38+10,000 yuan.

2.3.3 Strictly implement responsibilities, highlight key objectives, actively develop circular economy and build resource-saving and environment-friendly enterprises. According to the requirements of the higher authorities, in order to solve the production and domestic water consumption of mines and local enterprises and institutions, better save water resources and improve the comprehensive utilization rate of water resources, the mine conducted a full investigation and demonstration on the "mine water treatment reconstruction project" based on the principle of "less investment, quick effect and local conditions" and combined with the actual situation. After nearly a year's solid work, Zaozhuang Environmental Monitoring Station carried out sampling inspection on the "Jingting Mine Water Treatment Improvement Project". All the indexes of the discharged water meet the requirements of the Comprehensive Discharge Standard of Water Pollutants along the South-to-North Water Diversion Project in Shandong Province, and some water quality indexes can meet the Class III water quality standard of the Environmental Quality Standard for Surface Water, which completely meets the design and expected goals. Through the advanced treatment of mine water, the pollution to the surrounding environment and water quality is reduced, and the benign and sustainable development of the ecosystem is ensured.

2.4, pay equal attention to open source and throttling, and do a good job in the comprehensive utilization of "three surpluses"

In the utilization of "three wastes", the mine has done some work mainly in the aspects of boiler coal saving, slag and residual steam comprehensive utilization, and the starting point of the work is first to establish on a practical and effective basis. There are four boilers in operation in the mine, and the coal consumption per day and night is 34 tons, which is very high. On the premise of ensuring heating in winter, the mine actively explores coal-saving methods. First, adjust the thickness of coal in time, burn thick coal seam at high temperature and keep warm for a long time; When the temperature is low, the thin coal seam burns, which is convenient for rapidly increasing the boiler temperature. Secondly, the boiler slag is selected by the fireman, and the lump coke continues to be used, and the fine pulverized coal slag is screened out for high temperature furnace pressing. The third is to use wet raw coal to avoid forming thick smoke when landing. Fourthly, the coal gangue in raw coal is selected in advance to avoid the phenomenon of incomplete combustion and slow temperature rise when mixed with raw coal. Through these methods, only 3 1.6 tons of coal is used every day and night, 2.4 tons less than the original. According to 450 yuan heating 1.20 tons of coal, the heating boiler can save 1.296 million yuan in the whole winter.

In the utilization of slag, the waste heat of slag in this mine is initially controlled within 700-800 kcal/kg, and then reused after screening slag. Slag containing pulverized coal is used as auxiliary fuel, part of which is sold without pulverized coal, and the other part is used for underground track laying, so as to make the best use of it.

In terms of residual steam, in the past, the residual steam in the drying room and dressing room of bathhouses often spewed out in large quantities, and the surrounding environment was foggy and water vapor splashed, which not only polluted the environment, but also caused waste. This work is listed as one of the key tasks of energy saving and emission reduction in this mine, and a professional team is set up to carry out special treatment. The heating bag on the second floor of the bathhouse and the exhaust pipe of the drying room are led to the geothermal pool, and the water in the pool is heated by residual steam as shower water, so that the recovery rate of residual steam can reach 100%.
