摘要
针对杜儿坪矿8#煤层使用掩护式液压支架过程中出现的问题,通过研究8#煤层顶板岩性,对比3种不同液压支架的支护形式及适应性,得出该煤层应使用大采高、大初撑力的支撑掩护式液压支架。
Aiming at the problem of No. 8 coal seam in Du＇ erping coal mine in the process of using shield hy- draulic support, supporting forms and adaptability of three roof lithology of No. 8 coal seam. It concludes that shield setting load should be used in the coal seam different hydraulic hydraulic support are contrasted by researching the support of which has large mining height and large
