摘要
针对开滦蔚州矿业公司南留庄井四采区的煤层地质条件,通过对支架工作阻力的计算,建立了顶板结构力学模型,在综合分析煤岩结构的基础上,选择了合理的支架架型和工作阻力。
In this paper, based on analyse of geological conditions of 4th coal pick area of the Nan - liuzhuang well of＂ Kailuan （Yuzhou） Miningcompany, Working resistance of bracket is calculated and mechanical medel of roof structure is established . At last reasonable bracket frame and working resistance was successfully selected.
