Types and prevention of geological hazards in metal mines

This is the most common metal mine geological disaster, sudden strong, large scale, serious consequences, especially in the production process often due to the insufficient estimation of the amount of water in the mine, the mining process to punch through the old hole, through the permeable fault, the sudden water storage cave or underground river, resulting in a large influx of groundwater or surface water.

Sand collapse and mud gushing are often associated with mine water inrush disasters. The sediment and rock debris filled in the cave influx with groundwater, and some permeable faults and ground fractures often cause shallow Quaternary sediments to flow into the pit with the surface runoff. The result is that the tunnel is blocked by sand, the machinery and personnel are buried by sand, and even the mine will suffer a devastating blow in serious cases.

5. Waste water pollution:

The wastewater of metal mine mainly comes from mining wastewater, tailings wastewater and tailings reservoir percolation water, which is another important form of geological disaster of metal mine. It causes serious pollution to the environment and harmful effects on human health.

Suggestion

With the state's emphasis on metal mine geological disaster control and the introduction of relevant regulations, it is clear that enterprises are the main body of mine geological disaster control, so it is the responsibility and obligation of each mining enterprise to start the work of geological disaster control from mine design and continue to the closure of the pit, and constantly improve the control of metal mine geological disaster.

1. Improve the level of prevention and control, enhance the awareness of dangers, and establish the concept of sustainable development

 Improve the level of geological disaster prevention in metal mines.

2. Combine prevention with prevention

There are many kinds of geological disasters in metal mines, with different formation mechanisms and inducement factors. According to their different geological conditions, terrain characteristics, development and utilization degree of resources, as well as the distribution characteristics of hidden points, under the premise of maximizing and effectively utilizing resources, the principle of "mining while managing" should be followed from the beginning of mine construction. The establishment of disaster monitoring, forecasting, assessment information system, so that timely discovery, timely treatment, to prevent the main, prevention and treatment of the combination, to solve the contradiction between mining and geological disasters.
