Abstract
In order to improve the economic benefit of coal mines and the safety status of roadway support,according to no.5 coal seam occurrence condition,on the basis of numerical simulation for the scheme of roadway support.Roadway support effect monitoring shows that anchor combined support effect is good,the surface displacement of roadway declined and improved obviously.Roadway maintenance achieved good technical and economic benefits.关键词
