前言 为了多快好省地开发赋存在复杂水文地质、工程地质条件下的矿产资源,矿床疏干技术得到了日益广泛的采用。生产实践证明,矿床疏干对于防止突水淹井,流沙溃入井巷和提高露天矿的边坡稳定性等方面,确实是一种比较有效的技术措施。然而,世界上一切事物都是一分为二的,矿床排水疏干引起的地表沉陷这一新的工程 Preface In order to develop the mineral resources under the conditions of complex hydrogeology and engineering geology, the deposit dewatering technology has been adopted more and more extensively for how fast and economically. Production practice has proved that it is indeed a more effective technical measure to prevent water inrush from flooding well, runoff eruption into the shaft and slope stability of open-pit mines. However, everything in the world is divided into two parts: the new project of surface subsidence caused by drainage dredging in the deposit
