摘要
以311307工作面为研究对象,分析了巷道发生底鼓的机理,并采用FLAC3D模拟巷道底板采用卸压槽及注浆锚杆后底板应力、位移及塑性区情况。根据模拟结果可知,采用联合措施后底板最大底鼓量为105mm。此外,分别设计了卸压槽及注浆锚杆参数,通过监测底鼓量对治理效果进行检验。根据监测结果可知,联合治理措施取得了良好效果。
        Taking 311307 working face as the research object, the mechanism of the bottom drum in the roadway was analyzed. The FLAC3 D was used to simulate the stress, displacement and plastic zone of the backing plate and the backing plate of the grouting anchor. According to the simulation results, the joint was adopted. After the measure,the maximum bottom drum of the bottom plate was 105 mm. The parameters of pressure relief groove and grouting anchor were designed separately. The effect of the bottom drum was monitored by monitoring the bottom drum. According to the monitoring results, the joint treatment measures had achieved good results.
