摘要
根据煤矿采空区的地质采矿资料,分析了影响采空区地表稳定性的影响因素,建立煤矿采空区地表残余变形的计算参数,应用概率积分法计算出各层采空区活化产生的地表残余变形值,采用叠加的方式得出所有采空区活化引起地表总的残余变形值。综合考虑地表残余变形和地质构造等情况,对煤矿采空区地表的稳定性进行了分析和评估。研究成果对煤矿采空区土地利用和规划具有重要的应用价值。
In the paper,the author analyzes the factors affecting the surface stability,establishes the residual deformation calculation parameters of the surface according the geological and mining conditions in coal goaf.The author calculates the activation producing residual deformation values of the surface using the probability integration method in the layers,obtains the total residual deformation values using a superimposed manner,and analyzes and evaluates the surface stability in coal goaf with the comprehensive considerations of the surface's residual deformations and the geological structures.Research results are very valuable to utilizing and planning of the lands in coal goaf.
