白集矿深井回巷道相似模拟研究

本实验基于相似模拟试验方法,结合白集矿深井回采巷道的地质条件,运用和原型力学性质相似的材料,按照一定的比例模拟岩体和煤层。在满足相似的边界条件及初始条件下,在平面应变情况下通过对比三种支护形式的性能差异,定性分析围岩中主动支护和被动支护对巷道稳定性的影响。对锚梁网索联合支护结构的稳定性效果进行分析研究。

The Similar Simulation Study of Deep Well Roadway about Baiji Coal Mine

With the help of similar simulation experiment way,under the geologecoal conditions of deep well mining roadway in Baiji coal mine,this experiment uses material as like as mechanical properties of prototype, and simulated strata and coal according to certain ratio.Under the condition of satisfying simulation boundary condition and initial condition,and contrasting performance difference of three different support style on plane strain, this experiment will qualitative analysis influence about stability of roadway between active supportand passive protecting in surrounding rock.The experiment will study the function of anchor in supporting.futhermore analysis and sudy stability effect of bolt-mest and cables support structure.
