摘要
利用ADINA对具有巷道典型破坏的邯郸亨健煤矿2201回风巷进行巷道破坏数值模拟,得出了巷道达到稳定状态时,所需要的两帮的约束力。然后利用理论分析公式,根据实地测量数据,计算出巷道达到稳定时所需要的两帮约束力的解析解,并将二者进行了比较分析,得出数值模拟的约束力和位移与理论分析的两帮应力、实地测量的两帮位移的误差在10%以内,为巷道设计与加固提供了新的方法。
Utilizing large-scale finite element software which is called ADINA to simulate the destroying of the 2201 re -wind tunnel in Handan hengjian colliery due to it express the destroy of model tunnel. It can obtain the wanted sanction of laneway flank while the laneway reaching the steady state. And then utilizing theoretical analysis formulary to comulate the wanted analytic solution while the laneway stabilizes. Comparing the two results, the errors between numerical simulation sanction and theoretical analysis sanction, numerical simulation displacement and field measurement displacement are less than 10%, providing a new method for laneway design and reinforcement.
