Common permeable channels in coal mines
Surface water mainly refers to the rivers, lakes, reservoirs, water and rainwater on the ground near the mining area.
Groundwater mainly refers to aquifers, fault fracture water and old water.
The abandoned roadway and goaf are called old goaf. Water inrush may be triggered when mining encounters a goaf, andWith the harmful gas gushing out, the harm is even greater.
Atmospheric precipitation first seeps into the underground aquifer, and water from the aquifer rushes into the mine during the mining process.It is an indirect source of mine water.
Production water includes water mining, dust removal, coal water injection, fire grouting, water sand filling, etc.
