摘要
针对特厚煤层采场空间较大、工作面支护困难的特点,以斜沟矿23107工作面实际地质条件为背景,利用理论分析的方法,对大采高综放采场覆岩结构进行分析研究,建立顶板结构模型,计算工作面正常回采期间和来压期间的支架工作阻力,并确定采用ZF15000/26/40型放顶煤液压支架,为工作面的正常生产奠定基础。
In terms of lager motion space and strong mining disturbance in working face of top coal caving with large mining height,according to the practical geological conditions of 23107 working face in Xiegou Coal Mine,this paper analyzed the support structure of fully-mechanized top coal caving face with large mining height,and set up the roof structure model,and calculated the working resistance of suppport during recovery period and normal support period,and determined the stent models of ZF15000/26/40.This work may lay a foundation for the normal production of working face.
