Types of Disasters to Be Noticed in Mine Mining

Jinggong coal mining must face a series of wells from the ground facing the underground. Its production process is underground operation, the natural conditions are more complex, the main features of mining are the need for mine ventilation, there are five disasters: gas, coal dust, roof, fire, water .

1. Mine ventilation. Because the underground coal mine production is underground operation, the surface air will be mixed with harmful gas and dust during the process of entering the underground and flowing through the operation sites. At the same time, due to geothermal effects, human body and mechanical heat dissipation, moisture evaporation, etc., the temperature and humidity of underground air will increase significantly, resulting in poor climatic conditions and, therefore, ventilation of the mine.

2. Gas, mine dust disasters. In the process of extracting coal, gas and dust are generated. Gas and coal dust will explode under certain conditions, causing casualties and property losses; mined dust can also cause miners to suffer from coal and silicosis and cause pain to the miners.

3. Roof disasters. In the underground mining process, due to the pressure of the mine, the roof will collapse. If there is a loophole in roof management, there will be roof accidents.

4. Mine fire. Mine fire is also one of the major disasters in coal mine production. Once a mine fire occurs, it will not only result in the loss of coal resources, disrupt the arrangement of various tasks, but also often cause gas and coal dust explosions, which will increase the extent and scope of disasters.

5. Mine floods. During the construction and production of the mine, surface water and groundwater will flow into the mine through various channels. In order to ensure the normal construction and production of mines, various measures must be taken to prevent water from entering the mine or draining the water entering the mine to the ground. However, when the mine water inflow exceeds the normal drainage capacity, or during the mining work, old pond water or karst water is dug through. When it comes to groundwater, it can cause water damage.
