The Integrated Research About Pipe Flow And Field Flow In The System Of Mining Ventilation

Mining ventilation is the base of safe mining ,and ventilation network analysis and computation is the most important of ventilation system .It is the premise of safety management of ventilation to analyze and compute ventilation network accurately .It is defined pipe flow flowing that the gas flowing in the tunnel ,it is defined the field flow flowing that the gas flowing in the mine space and cave .This thesis is mainly about integration of pipe flow flowing and field flow flowing ,coupling computation the new wind pressure of flowing field ,then re-analyzing re-computing and re-analyzing the ventilation network .A new method of enhancing the accuracy of analysis and computation of ventilation network is proposed .With the specific example of the Xia Gou mine of Bin County of Shan Xi province ,the accuracy and feasibility of the integrating coupling computation is proved .
