摘要
鲍店煤矿传统撤架工艺存在顶板支撑不足、钢丝绳断裂风险、三角区支护不足、撤架效率低、撤架成本高问题,设计了一套包括停采支护、掩护支架自移、回撤支架、三角区支护优化的智能化快速撤架及配套技术.通过采用高强度聚酯纤维柔性网和钢丝绳支护系统,提高了顶板支护强度;掩护支架自移技术实现了自动化遥控操作,提高了撤架效率并降低劳动强度;快速撤架装置消除了钢丝绳断裂风险,缩短了撤架时间.该技术在 5316 回撤工作面应用结果表明,每班撤架数量从 6 架增至 7 架,8.5 d内完成安全撤架作业,安全经济效益显著.
Abstract
The traditional withdrawing frame technique in Baodian Coal Mine has problems such as insufficient roof support,risk of steel wire rope breakage,insufficient support in the triangular area,low withdrawing frame efficiency,and high withdrawing frame costs.A set of intelligent rapid withdrawing frame and supporting technology is designed,including stopping mining support,self movement of shield bracket,withdrawal bracket,and optimization of triangular area support.By using high strength polyester fiber flexible mesh and steel wire rope support system,the strength of roof support is improved;The self movement technology of the shield bracket achieves automated remote control operation,improving the efficiency of withdrawing frame and reducing labor intensity;The rapid withdrawing frame device eliminates the risk of steel wire rope breakage and shortens the withdrawing frame time.The application results of this technology in the 5316 withdrawal working face show that the number of withdrawing frame per shift increase from 6 frames to 7 frames,and the safety withdrawing frame operation is completed within 8.5 days,with significant safety and economic benefits.
