根据煤锚杆锚索联合支护技术的优越性,对河林矿V7 7-2工作面运输巷道锚杆锚索联合支护技术进行了探究。为了确保河林矿V7 7-2工作面运输巷道锚杆锚索联合支护设计的可靠性,通过运用FLAC3D程序对其进行了模拟分析,得出河林矿回风巷道煤围岩垂直位移最大为95.043 mm,所受应力垂直最大为2.1711 MPa,支护效果较好,结果表明河林矿V7 7-2工作面运输巷道锚杆锚索联合支护方法的可行性,可以进行下一步工程实践。
According to the superiority of coal anchor combined support technology to mine V7 7-2,River Forest haulage roadway bolt anchor combined support technology to explore.In order to ensure that the Forest River Mine V7 7-2 working face roadway bolt and anchor combined support to the reliability of the design,through the use of FLAC3D program to simulate the forest,come to the river mine ventilation roadway coal rock 95.043 mm maximum vertical displacement,vertical stress maximum 2.1711 MPa,supporting effect is good,the River Forest Mine V7 7-2 working face roadway bolt and anchor combined support method is feasible,can practice the next step.
