The Ground-Water System and Possible Effects of ...

Future underground coal mines will require dewatering when they penetrate the Blackhawk-Star Point aquifer. A finite- difference, three-dimensional computer model was used to estimate the inflow of water to various lengths and widths of a hypothetical dewatered mine and to estimate drawdowns of potentiometric surfaces in the partly dewatered aquifer. The estimates were made for a range of ...

mining engineering: Mine Dewatering

Any open pit and almost any underground mine is a vast sump collecting water. The water naturally tends to accumulate at the bottom of the workings and the flow scours fine material and holds it in suspension. Dewatering a mine encompasses not only the water but also the fines contained in the water. The task is aggravated in some mines because fines can significantly alter the pH of the mine ...
