针对蒋家河煤矿单一厚煤层的巷道支护问题,对ZF1410工作面巷道支护方式进行改进。通过应力监测、位移监测对ZF1410工作面巷道新支护方案进行详细的分析研究。监测结果表明:ZF1410工作面在新支护方案下,巷道变形速度趋于平缓,巷道变形基本得到控制。应变值在锚杆、锚索承受范围内。
Aiming at the problem of roadway support in single thick seam in Jiangjiahe Mine, the improvement of roadway support in ZF1410 working face is improved. Through stress monitoring and displacement monitoring, a detailed analysis and study of the new support scheme of ZF1410 working face is carried out. The monitoring results show that under the new supporting scheme of ZF1410 working face, the deformation speed of the roadway tends to be gentle and the deformation of the roadway is basically controlled. Strain values in the anchor, anchor cable to withstand the range.
