摘要
由于大采高所使用的液压支架体型较大,在工作面回采期间保持液压支架的稳定性非常重要,因此,通过建立液压支架稳定性的力学模型,重点分析了倾角对液压支架的影响,并根据建立的模型分析了大峪煤业工作面回采期间液压支架的稳定性问题,可以为大采高工作面的设计和安全开采提供一定的参考。
Because of the large size of hydraulic support used in large mining height,it is very important to maintain the stability of hydraulic support during mining face.According to the established model,the influence of inclination angle on hydraulic support is analyzed,which can provide some reference for the design and safe mining of Dayu high mining face.
