【摘要】:基于廣西銅坑礦鋅多金屬礦區(qū)的通風(fēng)現(xiàn)狀,利用Ventsim軟件構(gòu)建礦區(qū)通風(fēng)井巷可視化仿真模型,計(jì)算分析風(fēng)流溫度在不同影響因子作用下的變化特性,歸納影響風(fēng)流溫度的主要因素,探尋首采區(qū)通風(fēng)降溫方案。研究結(jié)果表明:增加礦井總通風(fēng)量不能達(dá)到降溫目的,但局部風(fēng)量和通風(fēng)時(shí)間的增加可使巷道風(fēng)流溫度降低;在相同采礦背景條件下,采掘工作面越深,降溫要求越高;采掘工作面溫度與地表各月份氣溫變化規(guī)律一致,6,7,8月份采掘工作面溫度高于30℃時(shí)需采取降溫措施,建議采用井下集中降溫系統(tǒng)方案。
[Abstract]:Based on the ventilation status of the zinc polymetallic mining area in Tongkeng Mine of Guangxi, the visual simulation model of ventilation shaft roadway in mining area is constructed by using Ventsim software, and the variation characteristics of air flow temperature under the action of different influence factors are calculated and analyzed. The main factors affecting the air flow temperature are summarized, and the ventilation and cooling scheme in the first mining area is explored. The results show that the increase of mine total ventilation can not achieve the purpose of cooling, but the increase of local air volume and ventilation time can reduce the air flow temperature of roadway, under the same mining background, the deeper the mining face, the higher the cooling requirement. When the temperature of mining face is higher than 30 鈩,
