3、Huarun Coal. within the scope of the Ida, the geological condition is simple, with large amount of water inflow and gas emission in prominent danger. The annual output of the mine is designed 0.90 million tons, length of service 67 years. It uses the process of opening up by inclined shafts and long
4、wall retreat mining method of the “Flayer style“ mining for the whole floor in the working face. It selects the central parallel ventilation in the coal mine ventilation design, calculates the required air volume of the mine the and ventilation resistance in two periods and selected the major fan. T
5、hen it calculates the ventilation electric costs of every ton, draws ventilation systems and ventilation network diagrams and brings out the measures to prevent the main mine disasters. Combined with the actual situation fully, this design actively adopts feasible and advanced technologies, which la
