The design of 1.8 million tons annually. Mine is relatively stable within the coal seam occurrence inclination 12-17 °, the average coal thickness 5.0m, relatively high gas emission, Water as well. Geological data in accordance with the actual situation of the mine to develop and prepare the preliminary design of the way, the mine decided to increase the dark shaft down the inclined shaft mining, the design of integrated mechanized mining recovery layered process, inclined longwall mining law, with all the inter-drop method goaf deal. Mine and transport, mine hoist, mine drainage and mine ventilation systems and other computing equipment selection, as well as mine safety technology and environmental protection measures required to complete the preliminary design of the entire mine. All mine mechanization, use of advanced technology and high production and high efficiency have been achieved from the modernization of the experience of mine, so as to achieve good economic and social benefits. |
