摘　　要：超深井急倾斜薄矿脉开采地表岩移主要是由浅部矿体开采引起的,其岩移主要表现为空区覆岩顶板两端受未冒落顶与底部废石的支撑形成"厂"型弯曲和移动拱,并逐步向上扩展延伸至地表。通过采用三维数值模拟方法对吉林某金矿开采过程的模拟计算,得出超深井急倾斜薄矿脉开采的地表最大下沉量和地表岩移范围的变化规律。The surface strata displacement of steeply inclined thin vein in ultra-deep well was mainly caused by the mining of shallow orebody.It primarily presented as bedding and movable arch in the form of'厂'shape at both ends of goaf roof,which was supported by no-caving roof and bottomed waste,and gradually extended upward to the surface.Finally,the maximum surface subsidence and the variation of surface strata displacement range were obtained based on the three-dimensional numerical simulation of the mining process for a gold mine in Jilin province.

关 键 词：超深井 急倾斜薄矿脉 地表岩移 地表最大下沉量
