Industrial grade coal for coke, coal mine design recoverable reserves of 256.38 Mt, the service life of 101 years. The mine shaft design used mainly to the level of opening up more, divided into four levels, After the extension is divided into five four mining area. Four levels of operation for the Southern District Shihmen 3 # 2-mining area, using single-wing, mining, production of a face, When production of mining area for a number. 4 level spacing little seam, a joint arrangement. Designed to determine the level of roadway four coal transport belt use four auxiliary transport level using eight tons of explosion-proof motor vehicle traction battery 3 tons fixed tub transport, mining method used for longwall mining, coal mining technology for fully mechanized coal caving technology. Roof approach for the entire cross-loading method.
