Abstract：By using analogy theory and optics-elastic stimulated experiment, the stress field specialty of the surrounding rock in coal face and its influencing relation mutually are studied. It attains the law of the stress distribution, the extent of the stress concentration, the influencing range and its influencing extent. It is considered that the conclusions have theoretical and practical meaning to determining the reasonable mining sequence and the arrangement of mining roadway and its protective coal pillar in multi-coal seam mining. It also has provided some gist for the theoretical study on the ground pressure and productive practice.
