摘要
以营盘壕煤炭煤业21103工作面巷道为研究背景,采用理论分析、数值模拟和现场实测等手段,对弱胶结软岩巷道底鼓变形机理进行研究,得出影响巷道围岩变形的影响因素,提出连续抗滑桩支护的新方式,用以控制巷道底鼓,并对该支护方式进行实际论证。
Based on Yingpanhao coal mine 21103 working face roadways as the research background, the theoretical analysis, numerical simulation and field measurement, floor drum up of weakly consolidated soft rock roadways deformation mechanism is studied, it is concluded that the influence factors of influence of surrounding rock deformation of roadway, come up with new ways of continuous anti-slide pile supporting, floor drum up to control the roadway, and the supporting method is practical.
