Calculation Results

In order to reduce Shigetai coal mine ventilation resistance of mine ventilation system, using balanced ventilation principle Shigetai coal mine ventilation resistance of mine ventilation system was analysed and balanced, and the balanced ventilation resistance measure mine ventilation resistance in 2014-2015 simulation calculation. Results suggest that balanced ventilation measures implemented in mine ventilation resistance, coal mine ventilation resistance in the next two years not only with increased ventilation line length increases, but lower. Visible, balanced ventilation of mine has better technical and economic results are obvious, merits promotion.

The Membership Function

According to modern system security theory and method，a series of indexes to evaluate the system safety and reliability of coal mine ventilation system are established. In order to apply it into practice, the membership function is also introduced into the evaluation process. The formula to calculate integrated score of mine ventilation system safety and reliability were brought into the model. The above model was applied to evaluate safety and reliability of mine ventilation system and had achieved good results.

Theory Calculation

Mine ventilation system is serious pollution to the surrounding environment. Due to the air flow rate, high speed, strong noise radiation. In addition to the scientific and reasonable design for muffler, ventilation resistance loss calculation is one of the key successful factors of project design, in order to eliminate the noise pollution of mine ventilation system.In recent years,people's awareness level of the harm of noise rises ceaselessly, the environmental protection departments also gradually enlarges the management and punishment to noise pollution.The noise control of coal mine ventilation system with strong radiation and harm has become a pressing matter of the moment. Because the theory calculation of noise control design is fuzzy, Some environmental protection company implement noise control by virtue of experience or imitation of other engineering, leading to a series of problems, such as noise control can not reach the design standard, large ventilation resistance, energy consumption increased, regeneration noise exceed the standard, system vibration. Based on the systematic study for engineering design, i summed up the theory calculation rule for the coal mine ventilation system noise control, as reference to technical personnel.
