云南省东川铜矿区主要地质灾害与致损机制防控

云南省东川铜矿区因位于乌蒙山系侵蚀区和现代活动构造区，由于特殊的地形地貌、水文地质、新构造运动、植被、地层岩性和矿山开发等多因素耦合，东川铜矿区成为矿区地质灾害多发地区之一，这些诱发基本因素是矿山受损生态系统的致损机制。东川铜矿区开采历史较悠久且属于我国典型老矿山之一，由于长期的矿山开采和人类活动的影响，与本区特殊自然因素耦合等，一系列矿山地质灾害接踵而来，主要包括崩塌、滑坡、泥石流、地面塌陷、地裂缝、矿坑突水等，预防和治理矿山受损生态系统成为当前和今后首要难题之一。

Main geological disasters and accident prevention of Dongchuan copper orefield in Yunnan Province

Dongchuan copper orefield is located in Wumeng Mountain erosion areas and modern active structure zone, which becomes one of geological disaster-prone areas due to the special topography, hydrogeological condition, the new tectonic movement, vegetation, strata lithology, mine development in this region. Dongchuan copper orefield has a longer exploitation history and belongs to one of the typical old mines. Long-term mining, human activities and special natural factors cause series of geological disasters in mining as follows ： collapse, landslide, mud-rock flows, ground subsidence, ground cracking, and water penetration. Therefore, accident prevention becomes one of the most important problems to solve.
