| Abstract: | This paper synthesizes the observations in situ, the results of the laboratory test and the finite elements analysis, presenting the rule of the abutment distribution around the working face. The main factors affectig the abutment distribution are discussed. The estimating equation of determining the peak zone of abutment pressure using known parameters is given, thus, it provides the basis for determining the rational size of the sublevel chain pillar |
