Design to include: mining geological features, summary and partmentalized realm and reserves, mine work system and design production ability and service of schooling and exploiting and basic partmentalized arrange tunnels, mine ventilation system, mine disaster prevention and improve the gas drainage rate measures. According to the design requirements, this field design annual production capacity is 90 tons/year, service of schooling for 54 years, the mine shaft adopts two level elevation expand, a level correlation between 300m, two levels elevation 550. Decorate two face mining. Long wall mine adopt prehensive mechanized mining to law. Mine ventilation mode for partition drawertype ventilated, mining ventilation mode for backward type, the coal face for ushaped ventilated, uplink ventilated. This design is pleted with the wind site design, roadway air resistance calculation, and pleted the main fan selection. According to the design and the basic situation of mine ventilation system, this paper puts forward the gas, fire, roof, hot against the prevention measures such disasters. Keywords: developing design。本設計完成了用風地點風量設計、巷道阻力計算,并完成了主要通風機選型。礦井采用走向長壁綜合機械化采煤法。根據設計要求,本井田設計年生產能力為 90萬噸/年,服務年限為54年,礦井采用兩個水平立井開拓,一水平標高為300m,二水平標高為550。摘 要本設計進行的是杏花礦三井的礦井通風設計。設計包括:礦區(qū)概述及井田地質特征、井田境界及儲量、礦井工作制度和設計生產能力及服務年限、井田開拓及基本巷道布置、礦井通風系統(tǒng)、礦井災害防治和提高瓦斯抽放率的主要措施。采區(qū)布置兩個工作面。礦井通風方式為分區(qū)抽出式通風,采區(qū)通風方式為后退式,采煤工作面為 U 型通風,上行通風。根據設計礦井的基本情況和通風系統(tǒng),初步提出了瓦斯、火災、頂板、熱害等災害的防治措施。 ventilation design。行政區(qū)劃隸屬于雞西市雞東縣哈達鎮(zhèn)境內。20′,勘探區(qū)兩側是東海礦和城子河煤礦,北側是正陽煤礦,南側隔穆棱河和雞東鎮(zhèn)相望。 杏花礦交通位置圖 地形地勢礦山地形大部分屬丘陵地形,北部及中部皆為山崗地帶,崗溝起伏不平。 河流、湖泊、沼澤的分布杏花礦區(qū)內最大河流為穆棱河,由西南向東呈蛇形流經本區(qū)深部。穆棱河夏、秋季水量較大,最大流量為3120立方米/秒,在井田深部流過。哈達河流在井田東部境界附近流過影響也不大。 礦區(qū)氣象條件區(qū)內屬寒溫帶大陸性氣候
