Steel mine support refers to the artificial structure installed in the mine roadway to support the rock. Its function is to control the movement of surrounding rock and prevent the surrounding rock from falling, so as to maintain the safe use space of roadway. According to material cent has wood, metal, stone material, reinforced concrete bracket to wait.
Steel mine support is the support equipment of fully mechanized mining face, whose main function is to support the roof of the stope, maintain safe working space, and move the mining equipment of working face. According to the characteristics of the structure and the relationship with the surrounding rock, the mine supports are generally divided into three categories: support type, cover type and support cover type.
Steel mine support is a structure used to control the mine pressure in coal face. The form of pressure outside the mining surface ACTS on the hydraulic support. In the mechanical system of the interaction between the mining support and the surrounding rock, if the resultant force of the supports of the mining support is exactly the same line as the external load force of the roof acting on the mining support, the mining support is very suitable for the surrounding rock of the mining surface.
