Analytical Study on the Structural Characteristics of Hydraulic Support under the Load of Comprehensive Mining Face
Mastering the mechanical characteristics of the hydraulic support is of great significance to ensure the safe production of the mine,and the existing research on the structural strength of the hydraulic support mainly focuses on the load acting on a single support,rather than the hydraulic support support system of the fully mechanised coal mining face.Taking the hydraulic support system of coal mining face as the research object,the mechanical characteristics of the hydraulic support system of coal mining face and the stiffness characteristics of the key support members under different working conditions are analysed through theoretical analysis and numerical simulation.The weak points of the hydraulic support structure were identified.and proposed reinforcement methods.The results of the study can be used to realise the safe and stable operation of the hydraulic support system in the comprehensive mining face,so as to improve the safety and productivity of the mining operation.
