Abstract As for the difficulties in the optimization of roadway layout optimization in Guangxing Mine, dislocation layer system is implemented in the roadway layout for optimization design, improving the recovery rate of coal resources. On the basis of the analysis of the traditional dislocation layer system, according to the height of roadway, thickness of coal seam and theory of dislocation the traditional dislocation layer system were optimized and this optimized dislocation layer system is applied not only to top coal caving but also to the method of full-seam mining. Depending on the actual geological condition of Guangxing Mine, different plans of roadway layout are proposed and compared to select the best one, effectively improving the recovery rate of Guangxing coal mining.
