摘要
分析了煤峪口矿14号层408盘区近距离薄煤层工作面顶板及上覆11号、12号合并层采空区冒落情况分析,计算了408区采用ZYB4400/8.5/18液压支架载荷及支护强度,实测了支架载荷及支护强度,分析验证了ZYB4400/8.5/18液压支架在14号层408盘区近距离薄煤层工作面采场的支撑能力。
The article analyzed the falling situation of close thin coal seam roofs and gobs of No.11 and No.12 overlying merger layers of Panel 408 of Seam 14 in Meiyukou Mine. The supporting load and intensity of ZYB4400/8.5/18 hydraulic support were calculated and were measured. The results verified the hydraulic support ability in the close thin coal seam working face.
