Mine hydrogeological types and prevention measures of groundwater influence on mining

3 Related preventive measures

3.1 Clarify the evaluation content of hydrogeological exploration

Through the above introduction, we know that the hydrogeological types of mines are very diverse, and groundwater will also have a greater impact on the actual mining engineering. Therefore, it is necessary to clarify the evaluation content of hydrogeological exploration. ① When the corresponding staff does not carry out the exploration work, it is necessary to fully view the relevant data of the exploration area, and carry out the actual exploration on the basis of understanding the basic situation. In the process of exploration, it is necessary to delineate key indicators, and then collect a large amount of data information. When selecting survey sites, the number should be as large as possible to avoid missing problems. (3) Hydrogeological exploration work should be completed at different times, such as dry period and wet period, and the exploration methods adopted should be different. There will be some changes in the natural environment, using a variety of methods, can be better hydrogeological exploration work. (4) The corresponding staff need to start from multiple aspects when evaluating hydrogeological exploration, so that more accurate and comprehensive data information can be obtained to prevent accidents.

3.2 Attach importance to the testing and research of water quality

China's mineral resources mining work after a long time is also in continuous development, almost reached the peak state, if you want to continue mining, you must develop in the deep direction. The hydrogeological types of mines show an increasing state, and the influence of groundwater is also gradually expanding. Therefore, it is necessary to improve the testing and research on the water quality, obtain research results, and constantly improve the quality of the test, so as to provide more preventive countermeasures. When water quality is sampled, groundwater is usually sampled twice a year, during periods of low and high water. According to the actual situation, the sampling times can be increased. When the water quality is fully understood, the number of samples can be appropriately reduced. The types of groundwater are also very many, according to different basis, can be divided into different. If based on aquifer, it can be divided into pore water, fissure water and karst water. Different types of groundwater have different hydrological properties. After a thorough study of water quality data information, it is possible to understand the changes in water level and volume. According to a series of analysis, it is known that the hydraulic properties will affect the formation stability of the mine to a certain extent, and may lead to the formation deformation.

3.3 Strengthen the investigation of potential security risks and increase capital investment

Improving the investigation of safety hazards can effectively prevent the occurrence of geological and hydrological accidents. Some dangerous areas, often occur some accidents, for these areas to focus on the investigation. It is necessary to fully study the basic situation of the mining area, and when the investigation is carried out, it can not leave dead corners and investigate thoroughly. The corresponding technical personnel can be assigned to carry out special monitoring work, the 24-hour duty system can be implemented, appropriate monitoring methods can be adopted to collect data, and the deformation of dangerous rock mass can be prepared every day. Second, we need to increase capital input. In the process of mining work, if some safety risks are found, measures should be taken immediately to avoid the risks, timely evacuation of the surrounding residents, and residents should be given some relocation subsidies to protect the rights and interests of residents. If a security incident has occurred, measures should be taken to deal with it. The corresponding departments should also improve the management of mining rights, ensure the smooth rectification work, improve the market mechanism, and ensure the order of the market.

3.4 Mechanism innovation

It is necessary to innovate the management mechanism in time, design a scientific and reasonable emergency management plan according to the actual situation, and set up a mining team with a high professional level. For some safety accidents that have occurred, we should prevent them in time. Around the mining area, tailings ponds are sometimes built, so it is necessary to do the monitoring and reinforcement of tailings dam body to effectively avoid dam break accidents, so as to ensure the balance of ecological environment to a certain extent. The corresponding management personnel must establish the concept of prevention, improve the duty of some dangerous areas, and always pay attention to the weather changes, if the rain weather occurs, it should be timely response measures, set up some safety buffer zone, effectively avoid disasters. Some geological and hydrological accidents often occur when mineral resources are exploited and used efficiently. Therefore, it is necessary to improve the prevention and control level, pay attention to the protection of the environment, and ensure the sustainable development of the ecological environment. In the development process of the mineral resources industry, gradually realize the value of resources, control the rapid economic growth to a certain extent, and carry out paid development of mineral resources, which can effectively prevent the occurrence of excessive mining, and also carry out certain macro-control of the market.
