摘要
潞安矿业集团公司五阳煤矿地质条件差 ,煤质松软 ,在煤巷掘进中一直采用工字钢棚支护。近年来 ,矿井储量日趋减少 ,采掘衔接紧张 ,不少巷道须在地质构造带或动压影响区内开掘 ,造成巷道支护变形严重 ,修复工程量大 ,直接影响生产安全和效益。因此 ,进行煤巷支护方式的改革已十分必要 ,2 0 0 0年五阳煤矿在 5 10 5工作面进行了锚网索支护试验。介绍锚网索支护的应用情况 。
Geological condition isn′t good and coal is soft in Wuyang coal mine of Lu′an coal group company,support adopt I-steel shed in coalroad driving,in recent years,reserves of coal mine is decreasing day by day,dovetailing of mining is tight,mant coalroad must mine in geological structure zone and influence of mining pressure region,make support is crushed out of shape,repair is very difficult safe of production and benefit is influenced.So reform of coalroad support is very important,cable anchor support is tested in 5105 workface of Wuyang coal mine in 2000.This paper introduces applicated situation of cable anchor support,existing problem and improving measure.
