| Abstract: | In order to effectively control the roof of longwall working face with single prop,a mechanical model of single prop shoe is built based on Class I dead-soft floor working face to analyze the distribution of load on the prop shoes.In addition,the rational prop shoe sizes including the thickness of prop shoe and the size of prop shoe are calculated.Through analyzing the existing support method,the rational prop shoe type and its parameters are determined to warrant the stiffness of supporting system.The support system shows its excellent supporting performance in the mine. |
