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 mining support. In the mechanical system of the interaction between the steel mine 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.
Steel mine support is an important part of fully mechanized mining equipment. The mining support can support and control the roof of the working face reliably and effectively, isolate the goaf, prevent the gangue from entering the working face and push the conveyor. The support of mine and shearer are used together to realize the comprehensive mechanization of coal mining in shandong province, solve the contradiction that the roof management in mechanical coal mining lags behind that in coal mining, further improve and improve the efficiency of coal mining and transportation equipment, reduce the labor intensity of coal miners, and ensure the safety of coal miners to the maximum extent.Mining support is a structure used to control the mine pressure in coal face.
