深部通风三维仿真模拟研究

Research on Three-dimensional Simulation of Deep Ventilation

随着矿井开采深度的不断增加,井下深部高温热害问题严重,由于深部的恶劣条件导致相关现场研究十分困难,利用通风三维仿真模拟技术进行深部通风系统分析是合理可靠的科学选择。应用Ventsim通风仿真模拟软件对河西金矿通风系统进行三维仿真模拟和系统能量损失分布模拟、河西金矿深部通风系统总需风量的相关计算,在模拟结果与理论计算的基础上,对模拟风量结果与临界需风量结果进行对比分析。为相似条件的深部矿井通风系统的模拟分析研究和降本节能增效提供了案例借鉴和数据参考。

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.
