摘要
针对淮南新区13#煤层,应用FLAC软件模拟综放面沿空掘巷留设不同宽度煤柱时围岩位移量的大小,并结合“软”、“中硬偏软”两个具有代表性的煤巷进行的工业性试验,进一步总结出这类煤层综放面沿空掘巷时需留设的最佳煤柱宽度及特殊的支护手段,对这类巷道的锚杆支护技术有参考价值。
According to Huai Nan new district＇s 13^# coal, We apply the FLAC to simulate rock displacement of different width pillar of coal gates close to gob in fully mechanized longwall top caving face, At the same time, unite two representative industrial test on coal road whose coal is ＂soft＂ and ＂middle hard leaning to soft＂, Further ; we conclude the optimized width and special support method in coal gates close to gob of fully mechanized longwall top caving face in the kind of coal seam. This method of road bolt support have very referenced value .
