针对神东煤炭集团某煤矿综采工作面回风顺槽积水量大、浮煤多的复杂工况,研究开发了ZQL2×6400/19/35WD型清煤排水专用超前支架组。通过应用证明:支架组设置的刮煤板机构、水泵提升机构和采用的无线遥控控制,实现了支护、清煤、排水平行作业,节省了成本,改善了支护方式和工人作业环境。
In view of the complex conditions of large amount of water and large floating coal in the return air groove of a coal mine fully mechanized coal face in Shendong Coal Group, the ZQL2 × 6400/19 / 35WD type advanced coal mine drainage advanced support group has been researched and developed. The application proves that the scraping coal plate mechanism, the pump lifting mechanism and the wireless remote control which are set in the support group realize the parallel operation of supporting, purifying coal and drainage, saving the cost, improving the support mode and working environment of workers.
