1."cges" geological exploration system software
This software was developed by the Gold Geology Research Institute of the Armed Police Force in 1990 after three years (1987~ 1990) on the basis of introducing Geolog software from Canadian IGC company. Combined with the characteristics of geological exploration work in China and the requirements of compiling geological exploration report results, the software has developed the Chinese version of GEOLOG in English. After successful development, the software has been applied to the reserves calculation of Wazidianyan Gold Mine in Pingquan County, Hebei Province, Xiadianyan Gold Mine in Zhaoyuan City, Shandong Province, Houqiyan Gold Mine in Qixia County, Shandong Province, Xin 'anhe placer gold mine in Yantai City, Shandong Province and Waijiahe placer gold mine, and achieved satisfactory results. Subsequently, version 2.4 of "CGES" was popularized and used in the geological team of the Armed Police Gold Command for nearly 10 years, and was purchased and applied by the Institute of Chemical Mineral Geology of the former Ministry of Chemical Industry, Beijing Geological Research Institute of Nonferrous Metals Corporation and the geological team of Shandong Zhaoyuan Gold Group Company. It has had a great influence in the field of gold geology. Practice has proved that the "CGES" China geological exploration system software, which is successfully developed by the Armed Police Gold Geology Research Institute and adapts to the characteristics of geological exploration in China, is completely suitable for use in geological exploration in China.
As the achievement of the Seventh Five-Year Plan, the software passed the expert appraisal hosted by the State Planning Commission on19910, and won the "Excellent Project" award of the State Council Electronic Information System Promotion and Application Office on 1992. Later, China Software Registration Center approved and issued the software copyright certificate, thus confirming the technical and legal status of the software.
1In April, 1993, with the support of the State Mineral Reserves Committee, the 14th Gold Detachment of the Armed Police Gold Command submitted the geological exploration reserves report of Jialu Gold Mine in Luonan County, Shaanxi Province by using the "CGES" software, which was approved by the Shaanxi Provincial Mineral Reserves Administration. This report is the first report on reserves submitted by geostatistics reserves calculation method and self-developed software system in China. The software has made great contributions to the popularization and application of geostatistics in geological exploration in China.
Li Weiming, a senior engineer in the Institute of Gold Geology of the Armed Police Force, is the main technical expert in developing "CGES" software. The successful development of "CGES" software made Li Weiming, a senior engineer, a pioneer in translating foreign software into Chinese.
2. Automated exploration and evaluation system for solid minerals (KPX software system)
The KPX software system is a cooperative project between the Ministry of Geology and Mineral Resources of China and the United Nations Development Programme. 1994, 199 1 development, 1993 completed.
This "system" takes the calculation of geological statistical reserves as the core, closely follows the specifications of China's mineral exploration and reserves classification (before 1999, that is, the specifications of reserves classification before GB/T 1766- 1999 was promulgated), and is completely applicable to the software system of China's mineral resources development from mineral exploration to mine production. It should be said that it is a survey and evaluation system with China characteristics. This feature is clearly marked in the basic functions and processes of the system (see chart).
Application of basic theories and methods of geostatistics (spatial information statistics)
After the successful development of "KPX", the former Ministry of Geology and Mineral Resources has been fully promoted and applied in the geological and mineral departments of various provinces (autonomous regions and municipalities directly under the Central Government), and has been promoted to the national geological prospecting industry.
3. Three-dimensional ordinary Kriging program system (3DOK) and SMICKS system.
These two softwares were developed by the geostatistics research group led by Professor Hou Jingru from the Department of Geology, University of Science and Technology Beijing. The former software was used by Team 3 12 of the Third Geological Exploration Bureau of the former Ministry of Metallurgy. It is used to compile the geological exploration report of Diaoquan silver-copper deposit in Lingqiu County, Shanxi Province. The report passed the expert review organized by the office of the former State Mineral Reserves Committee in April 1995.
"SMICKS" software system belongs to research software, and its content is spatial multi-information collaborative Kriging system.
4. "Gas or" (reservoir geological statistical analysis system)
The "GASOR" system was developed by Professor Wang Jiahua from the Computer Department of Xi Petroleum Institute. This "system" is based on the theory and method of stochastic modeling in geostatistics, and is used to establish models such as stratigraphic structure model, horizon model, sedimentary facies model, physical parameter model and sand body thickness change, thus forming the corresponding three-dimensional quantitative geological model.
This is a practical reservoir stochastic modeling software system, which has been successfully applied in Daqing, Shengli, Tarim and Liaohe oilfields since 1994. After that, it was integrated with other softwares to become Integrated Application Software Technology for Oil Rolling Exploration and Development, which was popularized and used by the Development and Production Bureau of China Petroleum and Natural Gas Group Company, and had great influence in the field of petroleum geology.
5. Kriging technology mine development system
The software system was developed for Dexing Copper Mine in Jiangxi Province, and applied to the production of this mine. In the production management of this mine, the core is to correctly estimate the ore grade and calculate the local block reserves, and the mining management has achieved good economic benefits.
In addition to the above geostatistical software, relevant schools, research institutes and geological teams have also developed geostatistical software for their own use, which is not listed here because of its small impact. The listed geostatistical software basically reflects the development and application level of geostatistical software in 1980s and 1990s in China. During this period, China's economic system is in the transition period from socialist planned economy to socialist market economy, and the planned economic system plays a leading role. From the research and development of geostatistics software, mineral resources management departments, schools, research institutes, design institutes, mining enterprises and other state-owned units at all levels of government play a decisive role. After entering the 2 1 century, China has been a socialist market economy system, the mineral exploration market is very active, and the investment subjects of mineral resources exploration and development are diversified. In this context, the development and application of geostatistics software, with the transformation of government departments and functions, unconditionally implemented the existing geostatistics software achievements. Because of the loss of stable management and services, it is difficult to play its role, and it is even more difficult to develop it again.
The research and development of geostatistics software has entered a new development stage. If it is simply divided in time, it can be divided into two development periods.
Phase I (1985~ 1998):
1985 is the first research and development period of geostatistics software in China.
1998 is the time when the Ministry of Geology and Mineral Resources and the State Mineral Resources Commission cancelled their reorganization and established the Ministry of Land and Resources. This period is the transition period of China's economic system, but the planned economic system still plays a leading role. After the National Mineral Resources Committee cancelled the new geostatistics science and technology work, this work was unconditionally implemented. Therefore, the end time of this period is set to 1998.
Phase II (1998 ~ present):
During this period, China has been a socialist market economy system and entered a period of free market competition. The research and development subjects of geostatistics software are diversified, and the research and development oriented to practical application has become a prominent feature of this period. Many powerful mining enterprises and economic entities have seen the great role and vitality of geostatistics in the mining economy, especially in the booming digital mines. According to the needs of the geological and mining fields and their own mining enterprises, the geostatistics software system has been developed and applied in multiple levels and directions.
The level of research and development has made great progress compared with the first period. At present, there are two representative and influential software systems active in China mining market: one is Dimine digital mining software system; The other is 3DMine mining engineering software. These are two unique software systems.
Dimine digital mine software system is jointly developed by Digital Mine Research Center of Central South University and Changsha Maidi Digital Technology Service Co., Ltd., which stands out among many related geostatistical software and represents the leading level of similar software in China at present.
After the software system was launched, it was quickly popularized and applied in nearly 20 large mining groups such as China Aluminum Company, China Minmetals Group, China Railway Resources Group Co., Ltd., Pangang Group Co., Ltd. and China National Nuclear Corporation. Now it has grown to nearly 100 mines, which has brought remarkable economic benefits to these mining enterprises. The software system closely combines the actual characteristics of China mine and advanced theory and technology, and is favored by many mining enterprises.
The software system takes mineral resources reserves as the economic lifeline of mining enterprises as the core and reserves dynamic management system as the main system. Around the main system, a series of system softwares suitable for China mine are developed, such as real-time monitoring and dynamic report system for mine production scheduling, which are very distinctive.
In the developed reserve dynamic management system, based on the widely used geological engineering database, a three-dimensional ore body model is established, and then a block model and a grade model are obtained for geostatistical Kriging estimation. This evaluation process can dynamically determine the ore body with the progress of production prospecting according to the economic benefit analysis, and achieve the best reserve effect, which is another major feature of the software system. In addition, in the process of establishing the three-dimensional model of ore body, the spatial shape of ore body and its relationship with exploration engineering grid can be clearly obtained, which is of great practical significance for mines to find reserve reserves, formulate mine production prospect planning and guide mine production exploration.
At the same time, it is particularly important to mention that the research and development of the software system has absorbed the past experience of developing and applying geostatistics software in China, learned the lesson of lacking stable R&D strength and technical service under the guidance of advanced geostatistics theory, strengthened R&D strength and technical service, and made stable and solid deployment. The development of the software system is based on the strong scientific research strength of the Digital Mine Research Center of Central South University and the School of Resources and Safety Engineering, and adheres to the three stable principles of stable organization, stable R&D talents and stable R&D funds, thus ensuring the advanced nature of the software system and the stability of technical services.
3DMine mining engineering software is a software system with independent intellectual property rights successfully developed by Beijing Sandiman Mining Software Technology Co., Ltd. under the cooperation and guidance of Anshan Mining Company and China Geo University (Beijing). The software takes the calculation of mineral resources reserves as the main function module, tracks the current mineral exploration norms and mineral resources reserves classification in China, organically combines advanced geostatistical reserves calculation methods with traditional reserves calculation methods, and better solves the demand for geostatistical reserves calculation methods in the international mining field and the current situation of domestic traditional reserves calculation. This is rare in similar software. It should be said that this is an innovative example, and it is also a prominent feature of this software in the calculation of mineral resources reserves in China. In addition, another feature of the software is its practicality. This feature is reflected in the block model of software.
Grade model (also called block model) is a database format, which is a concrete application of combining mathematical geology with grade spatial distribution. This is different from the traditional reserve calculation block method. When storing data, it is more like interpolating to replace a value than measuring a value. In addition, a major difference is that the value has a spatial reference. The third difference is that when the block model is opened, it is placed in the memory to realize dynamic operation, and many complex geological attributes, such as various isolines and boundaries, can be drawn as long as necessary.
At present, the concept of block model is introduced into mining software, and the space blocks with a certain size are determined within a certain range, and the corresponding blocks have a centroid point, which can store all the attributes. On this basis, the sub-modules are further divided to ensure that the blocks on the edge of the ore body are as consistent as possible with the boundary (curved surface) of the ore body, so as to obtain accurate estimation. The software uses geostatistics method and kriging method to estimate the grade distribution, which is practical and flexible, and fully embodies the advanced evaluation technology.
The practicality and scientificity of the block model greatly improve the reliability of the calculation process of mineral reserves and lay a good foundation for the scientific management of mine design and production.
After the software was put into the market, it has been applied in many mining enterprises and geological departments at home and abroad, and achieved good application results.
