摘要
在贵州山区的矿山集中分布区,存在由一些"上硬下软"岩体构成的复杂山体,这些复杂山体的稳定性较差,在特定的开采工艺下,上部岩体容易产生变形松动,再加上降雨的促进作用,极易引发矿区地质灾害,因此对此种特殊地质环境条件下的矿山,如何调整现有工艺,降低由于开采造成的对上覆岩体的扰动,保持山体的稳定,具有一定的研究意义。
The concentrated distribution area in the mountainous area of Guizhou mine,there is some"hard soft"rock composed of complicated mountain,poor stability of these complex mountain,in particular under the mining process,the upper rock mass deformation loose,coupled with the rainfall role,easily lead to geological disasters in mining area,so on the special geological conditions of the mine,how to adjust the existing process,reduce the mining caused the overlying rock mass disturbance,keep the stability,has a certain significance.
