| 为了解决庞庄煤矿-620上山煤柱综采工作面安全通过位置关系复杂的多位态空巷问题,研究和实施了超高水材料充填空巷技术.通过分析计算确定了超高水材料充填体的强度要求和材料配比,研究确定了充填空巷距离工作面顶底板间隔距离为5 m.工程实践表明,超高水材料充填多位态空巷技术成功解决了庞庄煤矿-620上山煤柱工作面过复杂空巷的难题,经济技术效益显著,对于综采工作面过空巷具有重要参考意义和推广应用价值. |
| 英文摘要: |
| In order to solve the diverse position abandoned laneway of safely fully-mechanized working face in Pangzhuang Coal Mine -620 coal pillar, this paper studies and implements the technology of filling diverse position abandoned laneway with super-high water materials. After analyzing and calculating, the intensity of super-high water materials filling body and the proportion of super-high water materials are confirmed. At the same time, the 5-meter space distance between the filling abandoned laneway and the top and bottom of fully-mechanized working face of coal pillar has been confirmed. The engineering practice show that the difficult problem of diverse position abandoned laneway in Pangzhuang Coal Mine -620 coal pillar has been overcome successfully by the technology of filling diverse position abandoned laneway with super-high water materials. Considering the remarkably economic and technological effects, the technology of filling diverse position abandoned laneway with super-high water materials is of important value to overcome similar engineering problems. |
