Environmental geological problems related to unreasonable exploitation and utilization of groundwater, such as aquifer depletion, groundwater table decline, land subsidence, desertification, salinization and surface vegetation degradation, have been initially identified in major plain basins. Focusing on the regional hydrogeological exploration in Ordos Basin, the total amount of groundwater resources in the basin was evaluated, and the hydrogeological exploration of Inner Mongolia and Longdong National Energy Bases in Ordos Basin was carried out in depth, and the groundwater development and ecological environment protection schemes were put forward, which provided the groundwater resources guarantee for the water supply of national energy bases. However, the accuracy of basic hydrogeological survey is not enough to meet the needs of national economic construction planning, which seriously limits the accuracy of global and regional evaluation of major groundwater resources problems; The evaluation results can not meet the needs of sustainable development and utilization of groundwater, which leads to unreasonable development of groundwater resources and a large number of environmental geological problems.

However, China's water-deficient areas have a large area and a large population, and the hydrogeological conditions are extremely complicated. Due to the limited scope of work and exploration demonstration, an effective cooperation mechanism has not been formed with local governments at all levels, and the timely promotion of demonstration results and the solution of water shortage for more people are limited. It is necessary to further explore groundwater in particularly serious water shortage areas and focus on solving the problem of drinking water safety for residents.

According to statistics, there are 300,000 square kilometers of serious water shortage areas, rocky desertification areas and areas with prominent environmental and geological problems in southwest karst areas, and there are more than 3,000 underground rivers. The completed work only covers serious rocky desertification areas 1/3, and only about 0/00 underground rivers/kloc-0 are investigated, which is difficult to meet the needs of large-scale rational development and utilization of karst water.

1. Employment status
China has 13 large coal bases and 55 planned mining areas. At present, most energy bases in China are facing the severe situation of intensified water crisis, frequent water inrush disasters, deterioration of ecological environment and destruction of regional aquifer system. According to preliminary statistics, 70% of existing coal mining areas are short of water, and 40% of coal mining areas are seriously short of water. Water disaster has become the "second biggest killer" that threatens coal mine safety production. In many areas, aquifers are drained or semi-drained, and many karst springs are exhausted. Water resources and environmental problems have become "bottlenecks" restricting the sustainable development of energy bases. By the end of 1980s, the major energy bases had basically completed the regional hydrogeological survey of1:200,000, which became the main hydrogeological basic data for base resource development. A series of special hydrogeological research work has been carried out in some areas. However, on the whole, the accuracy of hydrogeological survey in energy base areas is low, and the high-precision hydrogeological survey in some newly-built development zones and planning areas is still in a blank state. In addition, the resource development and environmental protection of energy base lack the effective support of new theories and technologies, and can not guarantee the sustainable utilization of mineral resources.

Hydrogeological survey of energy base is divided into two levels: regional survey and key regional survey. The accuracy of regional survey is1:50,000 scale, which mainly investigates the regional aquifer structure, distribution law, recharge and discharge conditions and groundwater environmental quality. The investigation of key areas mainly focuses on outstanding environmental geological problems, including the destruction of aquifer structure, the type and scale of water inrush disaster, the environmental quality of groundwater and the deterioration of surface ecology, etc., and its investigation accuracy is 1: 10000 scale.
Water-deficient energy bases in northwest and north China focus on investigating aquifer structure and distribution law, recharge and discharge conditions and their changing characteristics, evaluating the development potential of groundwater resources, providing long-term water sources and solving water crisis. The energy bases with high incidence of water inrush disasters in North China and South China focus on investigating the types, scales and occurrence conditions of water disasters, evaluating and predicting the degree and development trend of water disasters, and putting forward technologies and schemes for comprehensive utilization of groundwater and disaster prevention and control to reduce disaster losses.
