本文是基于设置在临涣和海孜两矿工业广场煤柱内新生界地层沉降变形孔的监测、地表水准测量、有关水文孔观测资料以及土工试验结果，对临涣矿区巨厚松散地层内部非采动沉降变形的特征与机理进行了较全面的分析。并简要分析该矿区地层非采动沉降对井筒稳定性的影响。以及与一般情况城市地表沉降的差异。 This article is based on the monitoring and surface leveling measurements of the Mesozoic sedimentation and deformation holes in the coal pillars of the industrial squares of Linqu and Haizi, as well as the hydrologic hole observations and geotechnical test results. The characteristics and mechanism of settlement settlement are analyzed comprehensively. And briefly analyze the influence of strata unconsolidation settlement on wellbore stability. As well as with the general situation of urban land subsidence differences.
