Abstract Considering the influence of stress distribution factor between layers，the combining research methods of the traditional rock pressure，elastic plane body theory and field measurement are adopted to analyze the issue of the coal face reasonable malposition setting under the condition of the combined mining face in close distance coal seam. The conclusions are obtained as follows：(1) The face malposition setting distance should satisfy the basic conditions calculated by the theory of the rock pressure. (2) Based on the influence scope of the lower coal seam abutment pressure got from the mechanical theory or the measurement analysis，the interlaminar stress influence scope is calculated by the theoretical method of semi-plane and get the correction value of the face malposition. (3) Comparing the face malposition correction value with the calculated result by the traditional rock pressure，the larger of the two face malposition value，and also satisfying the basic conditions calculated by the theory of rock pressure，is took as the reasonable malposition setting distance. Through the analysis of reasonable malposition setting in the context of actual production in Shigejie coal mine，the reasonable face malposition of 55 m is setted finally. In this condition，the safe and efficient production is guaranteed.

Key words： mining engineering close distance coal seams combined mining malposition half-plane body field measurement
