ZM70型支架牵引机在神东公司试验及应用

ZM70 Stent Traction Test and Application in God East

介绍了ZM70型支架牵引机的各项性能指标,入井前试验:空载试验和负载试验,设备运输试验;井下支架回撤模拟试验,试验表明该机的所有技术性能达到了设计要求,顺利完成了哈拉沟煤矿22402工作面5.5 m支架的回撤试验任务。为神东公司快速支架回撤技术提供了依据,为相似条件工作面的支架回撤提供了实践,对实现现代化矿井快速搬家具有借鉴意义。

Based on company stand retracement Shendong pressure problem,the company introduced first time in China ZM70 stent traction.ZM70 stent introduced tractor performance indicators,into well before test： no-load test and load test,equipment,transport test;underground support retracement of simulation test,results show that all technical performance of aircraft meets design requirements,the successful completion of face of Sahara Coal Mine 22402 5.5 meters support in experiments.God Withdraw East companies to quickly provide a basis for support,support for retracement face similar conditions provides a practical,fast moving to achieve a modern mine reference.
