Description

一种双巷道联合快速掘进排矸系统及方法 技术领域
本发明涉及一种煤矿井下巷道掘进及排矸技术，具体是一种双巷道联合快速掘进排矸系统及方法，特别适用于井下倾斜巷道的掘进施工。
背景技术
目前，井下倾斜巷道的开采大都采用“液压钻车+挖掘装载机+转载机+胶带输送机+矿车”的作业线，而液压钻车和挖掘装载机操作复杂，对操作人员日常操作熟练程度和检修人员维护水平要求较高，且液压钻车开采效率很低，需要工人劳动强度大，机械化水平低，造成巷道掘进缓慢；开采下来的矸石需要使用装载机进行装载，经过转载机转载运输到主巷道内，再由主巷道排出，暗斜巷道与主巷道相通需要开设多条巷道，一次只能完成一条巷道的开挖，工序复杂，安全系数低，造成工作效率低，造成出矸率低。巷道的掘进速度直接影响了煤矿的开采速度，如何能有效节省劳动力，最大效率的开挖巷道具有重要意义。
