摘要:
深井开采通风线路长,导致局部通风量不足、热空气无法及时排出和作业面附近热量聚集等问题出现。随着矿山开采深度的增加,高温热害成为深井开采面临的难题之一,在地温梯度和井下各类热源的作用下,深井环境更加恶劣。为了改善深井掘进巷道高温环境,提高深井局部通风散热效果,以国内某大型地下金属矿山深部掘进巷道为背景,对深井局部通风参数进行优化研究。利用FLUENT软件构建掘进巷道三维模型并对巷道温度场进行数值模拟,通过对比不同风量和风温条件下的巷道温度变化情况,优选出适用于深井掘进巷道的最佳局部通风参数,并通过现场试验对模拟结果进行了验证。研究结果表明:数值模拟与试验验证相结合的方法科学有效,改善了单纯依靠试验的传统方法存在的高成本和重复性低的缺点;数值模拟方法可以直观展示巷道风温分布特征,局部通风参数优化后能够有效改善深部掘进巷道高温环境,对深井开采局部通风降温具有一定的指导意义。
