摘要
针对某矿42103工作面回风巷受上方22煤和42102工作面多次采动影响后巷道围岩变形破坏严重的问题,采用侧向支承压力实测和理论计算方法,分析采空区下动压巷道顶板结构特点和顶板岩层运动规律。
Aiming at the problem that the surrounding rock of 42103 return airway is seriously deformed by the multiple mining of 22 coal seam and 42102 working face,uses the method of lateral abutment pressure measurement and theoretical analysis to analyse the characteristics of roof structure and roof movement rule.
