摘要
底鼓是制约巷道正常使用的不利因素,不仅会减少巷道有效通风断面,而且会在一定程度上影响巷道围岩支护体系稳定性。基于此,根据15062巷围岩岩性、受力特征等,对导致15062巷底鼓量较大的原因进行分析,并从优化巷道支护参数以及底板注浆等方面提出底鼓防治措施。现场应用后,15062巷底鼓量被控制在256 mm以内,取得较为显著的底鼓防治效果。
The bottom drum is an unfavorable factor that restricts the normal use of the roadway,which not only reduces the effective ventilation section of the roadway but also affects the stability of the roadway rock support system to a certain extent.Based on this,we analyzed the causes of bottom drum of 15062 lane according to the lithology and force characteristics of 15062 lane,and proposed bottom drum prevention and control measures in terms of optimization of lane support parameters and bottom slurry.After the application,the bottom drum volume of 15062 lane was controlled within 256 mm,and the bottom drum prevention and control effect was more significant.
