The Ventilation System Reasearch After The Capacity Of Third Mine Expansion In Jinchuan Group

This thesis on the basis of existing ventilation theory, combined with the field measured data and the advanced computer ventilation simulation technology, the application of mine (in JinChuan mine) the problems existing in the ventilation system is optimized, finally reached the "ventilation and reliable" and "wind DingChan" safety production target.The results showed that:(1) survey, test work of mine ventilation system is late ventilation simulation computer data base, the completeness and accuracy of the its data directly affects the simulation results to guide the production ability; (2) mine 1.5 million tons/year,1.86 million tons/year,3 million tons/year simulation error is within the scope of the permit; (3) from the field application effect, computer ventilation simulation technology for mine ventilation management, design and optimization provides a scientific and reliable, convenient and quick method.
