What is the water pump worker doing in the coal mine water pump room? Is there any danger?

Underground coal mining needs little water. As for why so many pumps are installed, it is because there is groundwater underground, which is between the remaining coal seams. Groundwater is an important part of water resources. However, because coal mining cut off its water flow system, it is necessary to pump the groundwater in the working face to the central water pump house, and then the water pump house will be discharged to the ground.

Coal mines are extremely wasteful and destructive to groundwater resources. Groundwater is an important water source in the city with excellent water quality. However, the state destroyed the ecological environment for money and interests, and wasted the ecological environment in vain.
