某硫铁矿地下开采地表变形预测及影响评价

Study on prediction and impact assessment of surface deformation caused by underground mining in a pyrite mine

某硫铁矿地表存在河流、农田、村庄、高压线及地质断层,因此地表不允许沉降变形。针对此特殊情况,采用数值模拟方法,对该硫铁矿地下开采可能引起的地表变形进行预测分析。预测结果显示,该硫铁矿的地下开采对地表河流、村宅基本不会造成影响,地表场地可以作为简单及以上级别的建筑场地使用。

Aiming at the special condition that the surface deformation due to the existence of river, farmland, village, highline and geological fault is not allowed, the possible surface deformation caused by underground mining of a pyrite ore mine is predicted by numerical simulation. According to the prediction results, there is no influence on the river and village houses from the underground mining of this pyrite ore mine, and the ground is satisfied to be used as construction site at a simple and above level.
