摘要
以李阳煤矿15102区段运输平巷为工程背景,采用数值模拟研究了3种不同的巷道支护方式在煤巷掘进时的围岩应力与位移的分布特征。数值模拟结果表明,采用全煤巷道的高强度锚杆锚索联合支护时巷道稳定性最好。
Based on the engineering background of 15102 headentry of Liyang coal mine,three different supporting systems were simulated to analyse the distribution of the stress and displacement of surrounding rock during coal roadway excavating. The results of numerical simulation showed that the roadway supporting system combined bolt and anchor cable had the best effect to the stability of surrounding rock.
