Control technology of roadway floor heave based on a new grouting material
Engineering Research ExpressAbstract In the mining process of the working face, mining activities will inevitably damage the surrounding rock of the roadway near the working face and pose a threat to the safety of coal miners. The stability of the roadway was of great significance for the safe production of coal mines. In this paper, a new type of grouting material

The Integrated Control Countermeasures on Floor Heave of Broken Soft Rock with High Ground Stress
Advanced Materials Research, 2014The floor heave is one of the key issues of surrounding rock stability control during the deep well mining process. To solve the problem about floor heave occupying the most of roof and floor convergence deformation, the author analyzed the engineering geological conditions of broken surrounding rock and the floor heave features in PanEr Coal Mine East
