摘要
为了提高煤矿的经济效益和巷道支护的安全状况,根据5号煤层赋存情况,在数值模拟的基础上进行了巷道支护方案的确定。巷道支护效果监测表明:锚杆联合支护效果良好,巷道表面位移明显下降,巷道维护状况明显改善,取得了良好的技术经济效益。
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.
