Adequate air volume in working face after mechanical refrigeration

摘要：

By analyzing the coal mine working face ventilation and cooling cost after mechanical method is adopted for temperature decrease, the relationship between air volume and ventilation cooling cost was established. And through mathematical analysis and specific applications of the model, the reasonable air volume is determined. With respect to the actual conditions of a coal mine, the air volume is figured out. In order to verify the correctness of the air volume by the new method, the Ansys model of ventilation cooling for the working face is established, and the effect of cooling under the air volume is simulated. The simulation results can meet the mine cooling requirement after being applied in coal mine, the cooling effect and the economic benefit are satisfactory.
