摘要
针对河北金牛能源公司邢东煤矿深部轨道大巷失修严重的现实问题,对原锚网支护方式做了理论分析,提出锚网索支架联合支护维修的技术方案,并在力学机理分析基础上,对邢东矿深井锚网索支架联合支护技术进行了系统分析和应用研究。现场效果表明,锚网支架联合支护巷修技术是适用于邢东矿高应力条件的经济可靠的支护方式。
In view of the difficult roadway support problem of deep portion soft coal seam in Jinneng group Xingdong Coal Mine, the combining support plan was proposed based on the analysis of support mode, and mechanics mechanism analysis was carried on comprehensive and systematical analysis and the combining support technology was researched in deep high stress soft crag roadway in Xingdong Coal Mine. The remit shows that the roadway support in Xingdong Coal Mine has obtained good technology effect and economic effect.
