摘要
为加强薄煤层巷道掘进期间的支护效果,探索科学合理的薄煤层巷道最优支护方式,将目前的纯被动支护变为主动支护,最大限度发挥围岩的自承载作用,强化支护效果,选定在31118薄煤层工作面下付巷180 m^300 m之间段巷道作为试验区域,分3段各采用3种不同的复合支护方式进行试验,并且在试验区域以外的巷道试用"大棚距矿工钢单棚加顶锚杆"复合支护作为日常掘进期间的主要支护方式。
During the excavation roadway support effect strengthening thin coal seam support, explore the scientific and reasonable thin coal seam optimum supporting way, change the pure passive for active supporting, maximize the self bearing capacity of surrounding rock, strengthening the supporting effect, selected in 31118 working face in thin coal layer pay Lane 180 meters to 300 meters between the tunnel as a test area, divided into 3 sections each with 3 different kinds of composite support of roadway test, and test ＂in the test area outside of the greenhouse from miners steel single shed plus roof＂ composite support as the main support daily during the driving support method.
