摘要

为解决观音山煤矿E0104工作面巷道围岩变化严重的问题,通过分析工作面在回采过程中的矿压显现特征,提出片帮冒顶控制技术及"高强恒阻支柱-锚杆-锚索-钢带"联合支护方式,并进行工程实践;结果表明:优化后的支护方案对巷道围岩控制鲜果更加明显,说明优化后支护方案的可靠性与合理性。
        In order to solve the serious problem of surrounding rock changes in the roadway of E0104 working face in Guanyinshan Coal Mine,By analyzing the characteristics of the mining pressure during the mining process. The paper proposes a roof-top control technology and a joint support method of "high-strength and constant-resistance pillar-anchor-anchor-steel strip" and carries out engineering practice. The results show that the optimized support scheme is more obvious for the surrounding rock control of the roadway. Explain the reliability and rationality of the optimized support scheme.
