Safety Management of Roof Support of Fully-mechanized Caving Face in Coal Mine
In coal mining,the roof of fully-mechanized caving face is prone to many safety hazards such as subsidence,fracture and support slide.In order to ensure the safety and stability of coal mining,coal mining enterprises need to strengthen the safety management of the roof of the working face.Based on this,the 713lower05 working face of a coal mine was taken as the research object,and the technical parameter support for the roof management was provided by monitoring the ore pressure of the working face.According to the support strength required by the roof of the working face,the support type was selected scientifically,and the corresponding safety management countermeasures were put forward according to the roof conditions under different conditions.
