摘要:
巷道高温是制约深部开采的一个重要因素。为了更好地发挥辅助通风设施的作用,提高短距离高温矿井的通风降温效果,采用数值模拟方法研究辅助通风设施对巷道降温效果。通过建立数值模型,设置有无辅助通风设施、不同辅助通风设施长度、不同辅助通风设施与墙壁之间的距离以及不同进气道风速等条件,分析掘进巷道的冷却情况。结果表明:无辅助通风设施的巷道仅靠增加进气道风速无法获得显著的冷却效果;在增加辅助通风设施的情况下,随着辅助通风设施长度的增加,掘进巷道的冷却效果越来越好,当辅助通风设施长度增加到一定程度后通风降温效果开始下降;增加辅助通风设施与墙壁之间的距离可显著提高通风降温效果;在辅助通风设施长度和辅助通风设施与墙壁之间距离固定的前提下,增加进气道风速可改善冷却效果,但随着风速增加,冷却效果改善越来越不明显。
