There are three coal block board main types of materials: special steel, polyethylene, polyurethane. Special steel plate coal block has sufficient strength, but relatively heavy, the installation of the use of heavy workload; polymer polyethylene block coal board to meet the intensity of blasting mining working environment, but the polymer polyethylene coal block to more flexible boards worse after deformation should not be restored, the need for re-processing; my company block the production of polyurethane not only coal plate light texture, easy to install, but also high strength, elasticity, and deformation can be rapid recovery.
