摘要
根据王庄矿52采区实际情况,介绍了在过空巷时采用工字钢、背板、锚网、槽钢+锚杆、锚索的联合支护的方法,实践表明,风桥的变形量得到有效地控制,支护效果和经济效益明显,解决了反复修复的一大难题。
According to Wangzhuang mine 52 mining area actual situation,introduced in Gob with I-beam,backplane,anchor,anchor,anchor cable channel + combined supporting method.The practice proved that,air bridge deformation effectively control,supporting effect and economic benefit is obvious,solving a problem of repeated.
