在我国煤矿矿井的开采过程中,随着其开采年限的不断延长和开采强度的增加,出现了矿井资源消耗过剩,以及一些断层和陷落的地质因素引起的开采问题,使得煤矿在开采过程中遇到一些孤岛工作面的情况。需要注重在这些工作面中尾注浆锚索作为超前支护方案大幅度降低煤矿工作面巷道的收敛量,维持开采过程的稳定性,达到超前支护的目的,保证煤矿矿井的安全稳定开采,采用这种锚索支护可以在采煤工作面超前支护中发挥其优势性作用。“,”In the process of coal mining in China, with the continuous extension of the mining life and the increase of mining intensity, there has been excessive consumption of mine resources, as well as some faults and subsidence geological factors caused by mining problems, so that the coal mine in the process of mining encountered some island working face. Need to pay attention to in the working face end grouting anchor cable as the advance support scheme greatly reduces the convergence coal mining working face roadways, maintain the stability of the mining process, achieve the goal of advancing support, guarantee the stability of coal mine safety production, adopt the anchor cable can exert its advantages in coal mining working face advancing supporting role.
