摘　　要：综采放顶煤工作面巷道在松、散、软煤顶下沿底板掘进支护工艺研究及技术攻关是淮北矿业集团公司“323”短板最难攻克的难题。神源煤化工公司煤层赋存较稳定,但四采区中组煤由于岩浆岩侵入穿插,使煤层结构复杂化,煤层原生结构较复杂,煤层极松软、大倾角、稍碰即碎,巷道在煤顶下施工支护难度大,通过不断研究与实践,形成了一套极松软大倾角厚煤层沿底掘进工艺技术体系。It is the most difficult problem for Huaibei Mining Group Company"323"short board to study and solve the supporting technology of roadway driving along the floor under loose,loose and soft coal roof.Shenyuan Coal Chemical Company's coal seam is relatively stable,but the middle group of coal in the fourth mining area is complicated by the intrusion and penetration of magmatic rocks,which complicates the structure of the coal seam.It is difficult to construct and support under the coal roof.Through continuous research and practice,a set of extremely soft and large-inclined thick coal seams has been developed along the bottom.
