摘要
以5-4071巷为研究对象,通过监测沿空掘巷围岩的侧向支承压力分布规律,制定沿空巷道围岩变形监测方案,对监测结果进行分析,提出了采用增大锚杆、锚索直径的措施提高支护强度,保证巷道的安全掘进。
Taking roadway 5-4071 as the research object,through monitoring the distribution law of lateral abutment pressure of roadway surrounding rock along goaf,the monitoring scheme of roadway surrounding rock deformation along goaf is formulated,the monitoring results are analyzed,and the measures of increasing the diameter of bolt and anchor cable are put forward to improve the supporting strength and ensure the safe driving of roadway.
