【摘要】 根据顾桥煤矿1117(1)工作面的顶板岩性与矿压观测实际结果,应用矿山压力基础理论的"砌体梁结构力学"模型理论和实测统计法,来确定液压支架的沿米支护阻力和合理工作阻力,通过分析比较,确定了合理的支架工作阻力参数,并为厚硬顶板工作面合理确定液压支架工作阻力提供借鉴。更多还原

【Abstract】 According to the roof rock feature of the 1117(1) mining face in Guqiao Coal Mine and the observing result of mine ground pressure,the support resistance along meters and reasonable working resistance of the hydraulic supports are determined by actual observation,a regression formula and the mechanical model of the "bond beam structure" in basic theory of roof pressure.Through analyzing and comparing,the reasonable parameters of support working resistance are determined.The reference is provided for the reasonable determination of hydraulic support working resistance at the thick and hard roof in fully mechanized faces.更多还原
