在倾斜煤层综采工作面,普遍存在着输送机和液压支架下滑的问题,即使是工作面倾角只有3°～5°,输送机有锚固装置,输送机和支架也经常向下滑移。一般特点是,倾角大时下滑现象明显;下行顺序移输送机比上行顺序下滑现象明显。一、下滑原因分析 In the fully mechanized face of inclined coal seam, there is a common problem that the conveyor and the hydraulic support slide downwards. Even if the working face inclination is only 3 ° ~ 5 °, the conveyor has an anchoring device, and the conveyor and the support frame also often slide downward. The general characteristic is that when the dip angle is big, the phenomenon of gliding is obvious; the descending order of the order conveyor is obviously lower than the ascending order. First, the reasons for the decline
