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 bolt and anchor combined support technology, the joint support technology of bolt and anchor in the transportation tunnel of V7 7-2 working face of Hailin Mine was studied. In order to ensure the reliability of the joint support design of the bolt, cable and anchor in the V7 7-2 working face of Hulin Mine, the FLAC3D program was used to simulate it, and the vertical displacement of coal surrounding rock in the return airway of Hulin Mine was the largest Is 95.043 mm, the maximum vertical stress is 2.1711 MPa, and the supporting effect is good. The results show that the joint support method of bolt, anchor and cable in V7 7-2 working face of Hulin Mine can be carried out in the next step of engineering practice .
