摘 要:根据神东矿区上湾煤矿1-2煤层四盘区特厚煤层赋存条件,以及与煤层相关的围岩条件,进行支架的关键技术参数选型计算,并根据神东矿区地质探煤钻孔,煤层厚度、煤层起伏情况,并结合神东矿区近年来支架实际使用情况,研究确定8.8 m超大采高液压支架的支护强度。Based on the occurrence conditions of the extra-thick coal seams in section four,1^-2 coal seam,Shangwan coal mine of Shendong mining area and the surrounding rock conditions related to the coal seam,the key technical parameters of hydraulic support are selected and calculated.According to the geological prospecting for coal drilling,seam thickness,undulation of coal seam and the application of hydraulic supports in Shendong mining area in recent years,the support strength of the 8.8 m hydraulic support of large mining height was studied and confirmed.
