Abstract:In order to solve such problems as small internal dumping space, long transport distance, and long exposure time of slope, the geological conditions of IV coal seam were analyzed, the mining technology which called cross mining and internal dumping with burying slope was proposed, the benching methods and working line layout were designed. Then the production intensity for cross mining and internal dumping in Zhahanaoer surface mine was synthetically determined in terms of equipment capacity, coal quality balance and internal dumping space. The exploitation amount of IV coal seam is 4.8Mt/a, and the advance rate of cross mining work line is about 350m/a.
