大采高工作面控制设备滑动工艺的研究与应用

Research and Application of Control Equipment Sliding Technology at Large Mining Height Face

综采工作面坡度较大的情况下,液压支架及刮板输送机随着回采推进,向下坡方向下滑,刮板输送机占据了滑出侧端头支护的空间也堵塞了安全出口,同时还增大了滑入侧切顶密柱的支护宽度,给采空区维护增加难度。利用伪斜开采的原理,采用调正两巷进度差,增加设备下滑阻力,同时采用单方向顶溜的方式可以有效的预防、控制、调整支架和刮板输送机的上窜下滑,大大节省了发生上窜下滑后人工扩帮增加安全出口和两巷端头维护的工作量,是大采高工作面控制设备上窜下滑的有效手段。

In order to solve the problems of larger slope and god maintenance difficulties in fully mechanized working face, theauthor adjusted the progress of the two lanes, increased equipment downtime resistance, used one-way chute to effectivelyprevent, control, adjust the stent and serape conveyor up and down, which significantly saved the workload of artificial expansionto increase the safety of exports and maintenance of the two ends of the road after the occurrence of the channeling down andproved to be the effective means to control channeling down at large mining height face.
