Title: Design of the Caving Coal Bearer under Metal Mesh with Hard Roof and Hard Coal Seam
Abstract: It is briefly analyzed the design of the high strength and light caving coal bearer used to mine bottom slicing under hard roof and hard coal seam.The feasibility and effective resis'tance of the support are determined by the theoretical calculation and rock burst observation.The key research points are obtained according to the mining condition of working face and measured data of rock burst.In addition, the design idea and principle of the support and the technical parameters of the ZF4600/19/30-type support are determined.With the verified correctness in site and the suitable parameters,the support can be applied to the working face under the similar situation.
