Study On Ventilation Technology For Da Shuitou Hign Methane Mine

On the basis of newly achievements in researches in the field of mine ventilation, a study on the ventilation technology for Da Shuitou high methane mine is put forward. Using the result of resistance survey, fan capability and calculation of ventilation network, the stability of ventilation network is analyzed and optimized. Base on the gas delivery in gob caving longwall face, B ventilation pattern for the Da Shuitou is proposed, and ventilation technologies for long flexible coal bed to solve the high methane.Considering the practical needs of the coal mine, for the technique path, we use the ventilation theory, calculation software and the result of some simulation.This study combine the ventilation system to ventilation pattern in work face and digging laneway. It is helpful not only for the Da Shuitou to improve it's safety actuality but for the other mines with high methane.
