摘 要:为确定不同倾角下加长工作面液压支架的适用性,采用理论计算、数值模拟的研究方法,对支架适用性分析,经数值模拟论证,多倾角工作面加长后,相应端面冒漏高度增加30%、33%、31%。液压支架立柱受力峰值普遍小于其支护强度;通过理论计算及数值模拟相互验证,ZZ8200/24/50型液压支架能够满足多倾角加长工作面安全回采。In order to determine the applicability of hydraulic support under different inclinations at different inclinations, the theoretical calculation and numerical simulation are used to analyze the applicability of the stent. The numerical simulation shows that the height of the corresponding end face increases by 30%, 33% and 31% after the multi-dip angle is extended. The ZZ8200 / 24/50 hydraulic support can meet the safe mining of multi-dip angle extended working face by theoretical calculation and numerical simulation. The ZZ8200 / 24/50 hydraulic support can meet the support strength of the hydraulic support column.
