I 摘 要 東榮三礦二井 是一個 年 生產(chǎn)能力 Mt 的新井。 東榮三礦二井 位于黑龍江省 雙鴨山 市境內。井田走向長平均 5 km,傾向長平均 3 km,井田面積為 km礦井工業(yè)儲量 Mt,可采儲量 Mt,服務年限為 67 a。 礦井設計采用多立井、雙水平、集中大巷、上山及上下山開拓,共劃分 9 個采區(qū)。 礦井絕對瓦斯涌出量 m3/min,為瓦斯礦井。 工作面長度 200 m,采用一次采全高采煤法。礦井采用 “三八 ”制作業(yè)。生產(chǎn)班每班 1 個循環(huán),日進 3 個循環(huán),循環(huán)進尺 m。 通風容易時期 一號風 井 總需風量 m3/s,礦井通風總阻力 ,風阻 Ns2/m8,等積孔 , 二號風井 總需風量 ,礦井通風總阻力 ,風阻 s2/m8,等積孔 , ,總等積孔 m2, 。礦井通風容易。 通風 困難 時期 一號風 井總需風量 m3/ s,礦井通風總阻力 ,風阻 Ns2/m8,等積孔 , 二號風 井總需風量 m3/ s,礦井通風總阻力 ,風阻 Ns2/m8, 等積孔 , 總等積孔 m2, 。 礦井通風 容易 。 設計礦井通風的噸煤成本 元。 關鍵詞: 礦井通風 ; 通風設計 ;通風阻力 II ABSTRACT This is a Dongrong three coal mine. The second well of Dongrong three coal mine coal mine lies in Shuangyashan, Heilongjiang province. It’s about 5 km on the strike and 3 km on the dip,with the km2 total horizontal area. The geological condition of the mine is relatively plicated. The minable reserves are Mt, with a mine life of 67 a. The design of the mine has been divided into 9 mining areas which are more vertical shaft, two levels, gathering main laneway, up hill mining and updown hill mining. The absolute gas emission rate of the mine is m3/min,and it is gaseous mine. The length of working face is 200 m, which uses fullymechanized coal mining technology, and fully caving method to deal with goaf. The working system is “threeeight”. Every mining team makes one working cycle, with three working cycle everyday. Advance of working cycle is m. The total air quantity is m3 per second of number one mine, the total mine ventilation resistance is Pa, the coefficient of resistance is Ns2/m8, equivalent orifice is m2, The total air quantity is m3 per second of number two mi ne, the total mine ventilation resistance is Pa, the coefficient of resistance is Ns2/m8, equivalent orifice is m2。 The total equivalent orifice is m2。 The mine ventilation is easy. At the difficult time of mine ventilation, The total air quantity is m3 per second of number one mine, the total mine ventilation resistance is Pa, the coefficient of resistance is Ns2/m8, equivalent orifice is , The total air quantity is m3 per second of number two mine, the total mine ventilation resistance is Pa, the coefficient of resistance is Ns2/m8, equivalent orifice is m2。 The total equivalent orifice is m2。 The mine ventilation is III easy. The cost of the mine ventilation is yuan per ton. Key words: mine ventilation; ventilates the design; ventilation resistance I 目 錄 摘 要 ..........................................................................................................................
