摘要
基于冲击启动理论,采用理论分析与数值模拟相结合,建立巷道支护系统抗冲击能力的计算方法,由此对全锚杆支护、锚杆锚索联合支护、锚索加喷层支护等三种支护方案的抗冲击能力进行理论计算,以此确定适合古山煤矿大倾角特厚煤层巷道的抗冲击支护方案。
Based on shock initiation theory,with theoretical analysis and number simulation,and then calculation method of shock resistance of roadway supporting system was built,so the shock resistance of fully bolt supporting,combine supporting of bolt and cable,cable supporting and spray layer were calculated,so the shock resistance supporting scheme of roadway with large inclined angle and extra thick coal seam of Gushan coal mine was confirmed.
