摘　　要：为保证矿井安全生产,对单侯矿6100N工作面采空区上覆岩层“三带”发育,顶板导水裂隙带发育高度进行分析。基于矿井地质条件,通过经验公式确定垮落带最大高度11.60 m,裂隙带最大高度45.78 m,确定导水裂隙带最大高度57.38 m;利用瞬变电磁法现场实测,确定顶板发育高度范围20~90.9 m,平均55.45 m,并最终确定6100N工作面顶板裂隙发育高度为57.38 m。In view of the development of"three zones"in the 6100N working face of Danhou Colliery,in order to ensure the safety production of the mine,this paper determines the development range of the water-conducting fractured zone on the roof of the 6100N working face.Based on the mine geological conditions,the maximum height of the caving zone is 11.60 m,the maximum height of the fractured zone is 45.78 m,and the maximum height of the water-conducting fractured zone is 57.38 m Based on the field measurement of transient electromagnetic method,the development height range of the roof is 20~90.9 m,55.45 m on average.
