摘要
通过建立大采高液压支架的稳定性力学模型,对大采高液压支架的失稳问题进行了分析研究,并针对济宁矿区某煤矿厚煤层工作条件,完成大采高支架的稳定性设计。经工作面现场应用,所设计的液压支架可以有效解决大采高工作面支架的失稳问题,提高了大采高工作面的回采率。
By establishing the mechanical stability model of large mining height hydraulic support,make a stability analysis of the instability problem of large mining height hydraulic support, and complete the stability design of large mining height support for the thick seam working conditions of a coal mine in Jining mining area, The field application in the working face show that the support can effectively solve the instability problem of the large mining support,improve the rate of recovery of face with large mining height.
