摘要
以铜陵某铜矿区为例,通过分析矿区的地层岩性和地下开采情况,并结合现场工程物探和钻探成果,分析了矿区地下开采引起的采空空洞及地表塌陷的原因。该塌陷区第四系覆盖层薄且松散,岩体破碎及裂隙发育是造成塌陷的基本地质条件,地下矿区开采形成的采空空洞是主要因素,在地表水和地下水及周边矿区爆破等因素作用下加剧了地表塌陷的产生和发展。
In this paper,Tongling copper mine is taken as a case to analyze the mining hollow and the collapse caused by underground mining,by considering the lithology of rock mass and the influence of underground mining,as well as the results of geophysics and drilling. The thin and loose quaternary overburden,the fragmentation and fissure development of rock mass in this subsidence are the basic geological conditions causing collapse. The mining hollow caused by underground mining is the main factor of the generation and development of surface collapse,which is intensified under the action of surface water,groundwater,and blasting in surrounding mining areas.
