The Study On The Adaptability And Analyze The Structural Intensity Using FEA Method Of High Cutting Hydraulic Power Support

The technology of the high height and synthetical mining is the productive and efficient method mainly used for mining the height of 3.5m to 5.0m coal coating. Because of this character, this technology was extended applied in our chinese many diggings. Based on academic analyse , the movement rule of the the high height and synthetical mining coping and the broken circs of coping were synthetically researched ,also,the factors of coping sinkage were analysed . Whether this mining method could be put in practice favorably,anther important factor is the stability of the high height and synthetical mining.The conception"force balance area"was used for estimated the stability of bracket efficient. In addition, this method was simple and convenient. Based the tested parameters data of the mine, the adaptability of bracket of ZY10800/28/63 was analysed.From the analyzing,the conclusion that the working resistance was sensible was drawed.some loading experiments for compents of hydraulic pressure brackets were investigated. The characteristics of stress distributing were concluded,so that it could provide some consultations for brackets designing.
