倾斜煤层中大采高液压支架稳定性研究

Study on Stability of Hydraulic Support for Large Mining Height in Inclined Coal Seam

针对某矿2502大采高工作面的液压支架稳定性控制问题,充分利用文献检索、现场调研、理论分析等工具,分析了特殊地质生产条件下液压支架发生倾倒、下滑等失稳情况的影响因素,制定了针对性的综合控制方案,对保持支架稳定性及采场支架—围岩管理提出合理化建议,以保障2502大采高工作面的高产高效生产。

Aiming at the stability control problem of hydraulic su pport in 2502 mining face of a certain mine,the paper makes full use of literature retrieval,field investigation,theoretical analysis and other tools to analyze the collapse of hydraulic support under special geological production conditions.In order to ensure the high yield and high efficiency production of 2502 large mining face,a comprehensive control plan is established to keep the stability of support and the management of stope support and surrounding rock.
