摘要
针对建庄矿4^(-2)205工作面胶带巷底鼓对巷道破坏较大,导致胶带运输巷运输系统运行被迫中断的情况,以建庄矿4^(-2)205工作面胶带巷底鼓问题为研究对象,应用数值模拟的方法,有效模拟出不同时间段巷道底板及围岩的应力分布情况,并根据模拟结果制定了底鼓的防治措施。
In view of the problem that the bottom drum of 4^(-2)205 working face adhesive belt roadway in Jianzhuang Mine is damaged greatly and the whole belt transport roadway can not operate normally, the bottom drum problem of 4^(-2)205 working face adhesive belt roadway in Jianzhuang Mine is taken as the research object. The stress distribution of roadway floor and surrounding rock in different time periods is effectively simulated by numerical simulation method.According to the simulation results, the prevention and control measures of bottom drum are formulated.
