摘要
综采支架工作阻力的确定一直都是采矿界的难题之一。文章以砚北井田5号煤为背景,以采场围岩控制为核心,采用数值模拟分析方法,给出了综采支架的合理工作阻力值。旨在为现场实现安全生产和科学管理以及综放支架的合理选型和支护阻力的设计提供依据。
The determination of fully mechanized support working resistance has been one of the mining boundary problem. Taking No. 5 coal of Yanbei Coal Mine as background and surrounding rock control of mining as the core, the article offers reasonable working re-sistance of the fully - mechanized mining support in order to provide the basis for the design of the safety production and scientific man-agement and reasonable selection and support resistance of the fully - mechanized mining support.
