大倾角综采工作面液压支架稳定性及过断层技术

Stability of Hydraulic Support and Fault Crossing Technology in Fully Mechanized Mining Face with Large Dip Angle

大倾角煤层综采工作面液压支架的稳定性成为研究的重点和难点。分析了液压支架受力状态和围岩之间的关系以及影响支架稳定性的因素,进行了液压支架防滑和防倒研究,并对过断层技术进行了探讨。

The stability of hydraulic support in fully mechanized mining face of the coal seam with large dip angle has become the focus and difficulty of research.This paper analyzed the relationship between the stress state of the hydraulic support and the surrounding rock,as well as the factors affecting the stability of the support,studied the anti-slip and anti-fall of the hydraulic support,and probed into the fault crossing technology.
