某露天铜矿集水仓清淤及新水平开拓方法探讨

A Brief Discussion on Dredging of a Sump in an Open-pit Copper Mine and Its New Level Development Method

某露天铜矿采区三面环湖,地表水体发育、地下涌水量大。复杂的工程地质、水文地质条件是采区集水仓清淤及新水平开拓的最大难题,该矿山采矿场通过多年的生产实践及理论研究,总结出了一套完善的集水仓清淤及新水平开拓方法,确保矿山每年能顺利度过汛期,并保证二级矿量充足。

An open-pit copper mining area is surrounded by lakes on three sides.Surface water body is developed and underground water inflow is large.Complex engineering geological and hydrogeological conditions is mining area drain sump desilting and level of new development has brought the biggest problem,the mine stope through many years of production practice and theoretical research,summarized a set of complete sets of water storehouse desilting and new level to develop methods,to ensure that secondary ore mining can smoothly through flood season every year and plentiful.
