摘要
煤矿采空区的位置、特征及残余变形是在煤矿矿区及周边进行生态环境治理及建设工程选址时需研究清楚的重要工程技术问题。新邱区某煤矿开采资料匮乏,为对采空区的现状及稳定性做出评估便于后期进行治理和开发,通过物探和现场调查对采空区位置进行探测验证,并基于概率积分法沉陷理论运用软件对新邱区某煤矿采空区残余变形进行预测。后期观察结果印证了预测结果的可参考性。研究成果可为该区域煤矿采空区上方建筑的地基残余变形监测工作提供参考。
Location,characteristics and residual deformation of goaf are important engineering problems that need to be studied clearly when ecological environment control and construction project site selection are carried out in and around coal mine area. Mining data of a coal mine in Xinqiu district are scarce. In order to evaluate the status and stability of the goaf for later treatment and development,position of the goaf is detected and verified through geophysical exploration and field investigation,and the residual deformation of the goaf in the mine in Xinqiu district is predicted by software based on probability integral subsidence theory. Later observation results confirm correspondence for the predicted results. The research results can provide reference and guidance for the monitoring of the residual deformation of the foundation of the building above the goaf.
