Calculation and model construction of mine air demand based on Panxi coal mine

Abstract

There are many more accidents of gas explosion in heading face than in other working faces. For this reason, the safety measures of the underground heading face have become particularly important. With the trend of the coal mining face becoming longer and longer, the requirements for long-distance excavation ventilation have been increasing. How to conveniently and efficiently solve the energy-saving problem of long-distance ventilation has become a hot topic. In this paper, the ventilation design scheme of the 7323 upper heading face in Panxi Coal Mine is determined based on the 7323 upper heading face in Panxi Coal Mine. In addition, through VB software, the function of accurately calculating the required air volume is realized to ensure that the local fan can provide sufficient air volume, which provides the current conditions for the analysis of safety technology and long-distance ventilation.
