The mine shaft opening up by the mine ventilation out of the central parallel-type, design capacity of 1.5 million t / a. Mine the main coal seam 2 layer, the average thickness of 2.18m and 2.35m.The mine field for the high gas, due to the fault effects of a partial enrichment of gas. in the context of spontaneous combustion is likely to seam.45-25 coal and the value of all coal ) division of spontaneous combustion of coal rank, gnition temperature by reducing the value of Well no danger of explosion of the dust, but large gas content Ida, soft coal to coal-based, so dust may be explosive. The spirit of "prevention first, safety first" principle, Hong Yang Mine in accordance with high gas, there is a tendency of spontaneous combustion and coal dust explosion in mine design. The design around the underground mining methods, min...
