摘要 ABSTRACT In recent years due to the coal mine accidents occurs frequently, the ventilation system of coal mine has become an important content of the preliminary design of coal mine. According to the actual situation ,Liu Liang kiln coal mine is designed. Combining the production safety and ventilation safety technology and the Liu Liang kiln of the ventilation system of coal mine the preliminary design has been carried on. Besides the design for coal mine safety problems - fire, analyses the causes of the disasters, designed the specific measures for disaster prevention and security measures, in order to ensure the safety of coal production and reduce the probability of accidents. According to mine resources, the design adoptethe production capacity of 1.2 million t/a.In addict, from Liu Liang kiln coal mine exploiting way and the reality of geological structure, the design divides the mining area, choose the reasonable ventilation system. the mining coal face and heading ventilation, ventilation facilities and underground structures have been designed preliminary.what is more,it choose the safe escape routes, also analyzes the rationality and reliability of mine ventilation system. Strictly according to coal mine safety regulations, coal mining design manual and other requirements and specifications, the design puts forward the adapting to the practical conditions of Liu Liang kiln coal mining face and tunneling working face ventilation way, and calculate the coal mining working face and tunneling working face to air volume, and the whole mine air flow. On the whole mine air flow has been carried on the reasonable allocation.
