Abstract In order to obtain the shape of rational stop line，a model test was undertaken to study the disturbing characteristics below roadway with the axis perpendicular to the excavation orientation during the excavation of upper mining face. The test site，Jining #3 coal mine has a deep coal seam. The PAC acoustic emission，static resistance strain gauge and digital speckle are utilized. The events development，the strains at different locations and the overall deformation of surrounding rock below roadway were obtained. The acoustic emission characteristics of similar material were monitored during the uniaxial compression experiment and the results reflected the damage characteristic of similar material sample. It is concluded that the rational stop line should contain the excavation influenced zone l1 of disturbed roadway，the influenced zone l2 ahead of mining face，and the minimum safety distance l to avoid these two zones to influence each other. During the upper mining face excavation，the scope of l，l1，l2 were obtained by monitoring the strain and acoustic emission characteristic of surrounding rock and the total deformation was monitored in below roadway with the method of digital speckle.

Key words： mining engineering acoustic emission rational stop line excavation influenced zone strain gauge brick digital speckle
