摘要
本文针对晋煤集团凤凰山矿154313工作面盘区应力分布情况,通过围岩变形机理分析、现场实测数据分析、数值模拟及现场实施验证等方法,得出了工作面支架额定阻力与顶板来压的对应关系,为今后工作面掘进巷道的支护和回采支架的选型及步距控制提供了参考依据。
In view of the distribution panel of the 154313 face of Fenghuangshan Coal Mine, Jincheng Coal Group, this paper employed such methods as the surrounding rock deformation mechanism analysis, field measurement data analysis, numerical simulation and field implementation validation, and found out the corresponding relationship between roof weighting and the working face support resistance rating, providing referential basis for the selection and step controlling support and the roadway drivage working for the future and stoping stents.
