Limestone | Minerals Crushing in Mining

2011-5-5 · Controlling groundwater is another important aspect of mining operations. Water is usually present at some depth below the surface; and once encountered by mining, open crevices, fractures, and solutional voids in the limestone may produce variable flows of groundwater. This inflow must be routed along drainage slopes and ditches to collection places where it can be discharged from the mine. Most operators eventually need to collect water in a sump, or low spot, within the mine and pump it out from that point. On rare occasions, a heading may intersect a fracture or void which releases hundreds of gallons of water per minute. If the problem cannot be remedied, a portion or all of the mine …
