摘要
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 Jiangjiahe coal mine roadway support problem in single thick coal seam,improved the 1410 fully-mechanized coal mining face roadway supporting method. Through the stress and displacement monitoring for 1410 fully-mechanized coal mining face,a new support scheme is analyzed and researched in detail. The monitoring results show that under the new support scheme of the 1410fully-mechanized coal mining face,the roadway deformation speed flatten out,the deformation basicall brought under control,within the scope of the anchor rod, anchor rope under strain values.
