Prediction and analysis of mining subsidence in Longdong Coal Mine

摘要: 为了对隆东煤矿开采沉陷进行预测分析，应用概率积分法建立了主断面开采沉陷预测模型，并结合煤矿地表沉陷预测参数，预测了主断面地表沉陷变形分布规律；根据采空区任意点沉陷变形预测模型，采用VB程序计算采空区任一点的沉陷、倾斜、水平变形值，进而对开采沉陷土地破坏程度进行了分级。结果表明，采空区地表呈“盆”状沉陷变形，盆地中心为平底状，从盆地中心至盆地边缘沉陷值逐渐减小，中度破坏程度土地面积为13.1 hm2，占沉陷总面积的57.9%。Abstract: In order to predict and analyze mining subsidence in Longdong Coal Mine, prediction model of main cross section mining subsidence was established by use of probability integration method, and distribution law of surface subsidence deformation of main cross section was predicted in combination with prediction parameters of coal mine surface subsidence. According to the prediction model of subsidence deformation of any point in goaf, subsidence, inclination, horizontal deformation value at any point in goaf were calculated by use of VB program, then damage degree of mining subsidence land was classified. The results show that subsidence deformation shape of the goaf surface is "bowl", shape of basin center is flat, subsidence value decreases gradually from the basin center to basin edge, moderate damage land area is 13.1 hm2, accounting for 57.9% of total subsidence area.
