摘　　要：山西斜沟煤矿属于特厚煤层矿区,其中23103工作面煤层厚度达到14.38 m。为研究斜沟煤矿特厚煤层开采地表移动变形规律,根据实测数据,对比分析了23103、18205和18111这3个工作面回采后地表移动变形。研究表明,山西煤田特厚煤层工作面在综放开采条件下具有充分采动角大、最大下沉值大、下沉系数大、地表活动剧烈等特点。研究为山西斜沟煤矿地表变形预测提供依据。Shanxi Xiegou Coal Mine belongs to an extra-thick seam mining area,which the thickness of the coal seam in the 23103 working face reaches 14.38 m.In order to study the law of surface movement and deformation in Xiegou coal mine's extra-thick seam mining,according to the measured data,the surface movement and deformation after the mining of the three working faces of 23103,18205 and 18111 were compared and analyzed.Research shows that the extra-thick coal seam face in Shanxi coalfield has the characteristics of large full mining angle,large maximum subsidence value,large subsidence coefficient,and violent surface activity under fully mechanized caving mining conditions.The research provides a basis for the prediction of surface deformation in Shanxi Xiegou Coal Mine.
