With the increasing depth of mining,the problem of high temperature damage in deep underground mine becomes serious,and the harsh conditions at the deep mine make relevant field studies very difficult.The use of three-dimensional ventilation simulation technology to analyze deep ventilation system is a reasonable and reliable scientific choice.In this paper,Ventsim ventilation simulation software is applied to simulate the ventilation system of Hexi Gold Mine in three dimensions and simulate the system energy loss distribution;the calculation of the total air demand of the deep ventilation system of Hexi Gold Mine is carried out,and based on the simulation results and theoretical calculations,the simulated air flow results and the critical air demand results are compared and analyzed.It provides a case study and data reference for the simulation and analysis of ventilation system and for cost reduction,energy saving and efficiency enhancement in deep mines under similar conditions.
