Bolt-mesh-anchor support design of fully mechanized caving face gateway
摘要
Abstract
Fully mechanized caving face gateway is coal roadway, and its deformation and destruction are serious under mining influence.In order to solve the support problem of such gateway,engineering analogy and theoretical calculation method were used in the paper based on the deformation failure character of gateway of first work face in Shanhe coal mine, then reasonable design was obtained, moreover, pre-stressed bolt's length, spacing between bolts,distance between rows and pretension force were put forward.Finally,the strata control observation dat shows that gateway deformation was under control by this plan, and the better economic benefit was obtained.关键词
