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。
The performance indexes of the ZM70 stents tractor are introduced, and the pre-well test is carried out: no-load test, load test and equipment transport test; the simulation test of the downhole support withdrawing shows that all the technical performance of the machine has met the design requirements and has been successfully completed The Halagou coal mine 22402 5.5m support the retracement of the test mission. Provided a basis for Shentong’s rapid support withdrawing technology and provided a practical solution for the withdrawal of supports on similar conditions, which is of great significance to the realization of modern mine quick moving.
