浅析大倾角综采工作面液压支架回撤技术

Analysis of Hydraulic Support Withdraw Technology Used in Fully Mechanized Face with Large Dip Angle

着重介绍了大倾角下行回撤通道顶板支护、回撤通道空间支护、下行回撤方案及支架设备撤除顺序。采用下行回撤技术解决了工作面液压支架回撤中的一系列难题,为不同条件下的综采支架回收方式探索了一条新途径。

This paper mainly introduced roof support and space support in downlink withdraw gateway, downlink withdraw program and the withdraw order of support equipment. Adopting downlink withdraw technology would solve a series of problems in the hydraulic support withdraw in the work face which explored a new way of fully mechanized mining support recycling in differ- ent conditions.
