Title: Study of Roadway Layout in Short Distance and Inclined Coal Seam
Abstract: The strata behaviors is acute when the roadway with the overlapping seams close arrangement in short distance and inclined coal seam based on the specific geological conditions.The loose circle distance is about 3 m,and the roof and side displacement is above 50 cm,so the supporting is difficult.The sphere of influence of the coal pillar is diffident between the horizontal and inclined coal seam from the method of numerical modeling,the wrong distance of conveying tunnel of the first face is 2 m,and the distance of air return tunnel of the second face is 8 m,so the tunnel will out of the sphere of influence of the coal pillar,the theoretical calculation coincides that.
