摘要以金山店铁矿东区为工程研究背景，采用地质调查、位移监测、数值模拟及理论分析方法，开展地质结构影响下的金属矿山地压显现机制研究。研究结果表明，随采矿进深，岩体结构面对采空区围岩地压显现的范围具有明显控制作用，在陡倾优势结构面作用下，采空区上盘围岩形成反倾岩壁，下盘围岩形成顺倾岩壁，上盘地压显现范围远大于下盘；地压显现特征差异明显，结构面主控区的巷道以断面整体偏转变形为来压特征，断层控制的巷道以顶板垂直垮落为主、来压更为剧烈；地压显现的空间错动效应是结构面产状和局部断层滑移综合作用的结果，表现为开采阶段巷道稳定、而已采及深部未采矿体的阶段运输巷道发生大面积连续垮塌冒落。

Abstract：Taking the east area of Jinshandian Iron Mine as the engineering research background，the occurrence mechanism of ground pressure in metal mines under the influence of geological discontinuities is studied using geological survey，displacement monitoring，numerical simulation and theoretical analysis methods. The research results show that with increasing the mining depth，the rock mass structure has a significant control effect on the range of the surrounding rock pressure around the goaf. Under the action of the dominant steeply inclined discontinuous plane，the surrounding rock on the upper wall forms an anti-dipping rock wall，and the surrounding rock of the footwall forms a dipping rock wall. The surface pressure of the hanging wall is much larger than that of the foot wall. The characteristics of ground pressure are obvious different in different regions. The roadway in the main control area of the structural plane is characterized by the overall deflection and deformation of the section，but the roadway controlled by the fault is mainly characterized by the vertical collapse of the roof，in which the incoming pressure is more serious. The spatial dislocation effect manifested by ground pressure is the result of the combined action of structural plane occurrence and local fault slip，which manifests that the roadway is stable in the mining stage，and the transportation roadway in the stage of mined and deep unmined body has a large area of continuous collapse and falling.
