【摘要】：為探索巷道風(fēng)流性質(zhì)與圍巖調(diào)熱圈參數(shù)的匹配關(guān)系,依托廣西銅坑礦鋅多金屬礦體,利用ANSYS軟件開展深井巷道風(fēng)流性質(zhì)與圍巖調(diào)熱圈參數(shù)匹配關(guān)系單因素及多因素正交數(shù)值模擬研究。研究結(jié)果表明:風(fēng)流溫度每升高1℃,圍巖調(diào)熱圈半徑減少0.6 m,溫度升高約0.2℃;調(diào)熱圈溫度對風(fēng)速、相對濕度均不敏感,調(diào)熱圈半徑隨風(fēng)速、相對濕度都呈先增加后不變的趨勢,兩因素分界點分別為速度5.0 m/s,相對濕度70%;以調(diào)熱圈半徑為考察目標(biāo),最佳入風(fēng)流方案為入風(fēng)流溫度291.15 K、速度7 m/s,相對濕度70%或90%;以調(diào)熱圈溫度為考察目標(biāo),最佳入風(fēng)流方案為入風(fēng)流溫度291.15 K,速度7 m/s,相對濕度70%。研究成果可為高溫礦山通風(fēng)降溫方案的優(yōu)化選擇提供參考。
[Abstract]:In order to explore the matching relationship between the wind flow property of roadway and the parameters of surrounding rock heat regulating circle, relying on the zinc polymetallic ore body of Tongkeng Mine, Guangxi,By using ANSYS software, the orthogonal numerical simulation of the relationship between the air flow characteristics of deep roadway and the parameters of surrounding rock heat regulating circle is carried out.The results show that the radius of the surrounding rock heat regulating circle decreases 0.6 m and the temperature increases about 0.2 鈩，
