动压下大断面巷道底鼓机理和治理对策

Floor Heave Mechanism and Countermeasures of Large Section Roadway under Dynamic Pressure

为解决采动影响下大断面巷道严重底鼓问题,采用理论分析方法,建立了采动影响下巷道底鼓力学模型,对大断面回采巷道底鼓特征、机理和控制技术进行分析。

To solve the serious floor heave of large section roadway because of mining influence, the theoretical analysis method is used to establish the mechanical model of roadway floor heave under the influence of mining. The roadway floor heave feature,mechanism and control technology of large section extraction are analyzed.
