1、 摘 要 矿井生产,其主要特点是地下作业,工作环境艰苦,自然条件复杂,通风和安 全措施显得尤为重要。各煤田所处的地理位置不同,煤层地质条件多种多样,开采 方法也就多种多样。 本设计是在金家岭井田原始地质条件下作的矿井初步设计, 金家岭矿为高瓦斯 矿井设计内容包含:井田概况及地质特征、矿井开拓、通风设计、矿井安全技术措 施,以及专题浅谈对综采放顶煤采煤法的认识。 井田概况主要包括矿区的地理、地形和交通;矿井的地理位置、井田范围;矿 区的气象条件、地震烈度、电源和水源的概况;井田地质特征、煤层及煤质概况以 及水文地质条件概况等。 矿井开拓分别论述了主井、副井位置选择、带区的划分、水平的划分以及开采
2、 顺序、带区的布置及装备、各巷道的布置等。 通风设计主要包括矿井通风系统的选择、矿井所需风量的计算及分配、全矿井 前期、后期的通风阻力计算以及对通风设备的选择等。 安全技术措施包括井下瓦斯预防、顶板管理、水灾预防、火灾预防、煤矿爆炸 的预防及粉尘防治措施等。 关 键 词 : 立 井 ; 高 瓦 斯 ; 倾 斜 长 壁 ; 带 区 ; 斜 巷 ABSTRACT The coalfield to the geography and varied geological conditions of coal, mining methods have varied. Mine production, i
3、ts main feature is underground work, work hard and complicated natural conditions, the ventilation and safety measures appears to be particularly important. This design is the mineral well first step design make under the condition of original geology of the mine of Jinjialing Coal Mine, This design
4、 contents containment: The well farmland general situation and geology characteristic, the mineral wells expand, safe technique measure of well ventilated design, the mineral well, and the feature of understanding on the fully mechanized top coal caving mining method. The field general situation of
5、the well includes geography, topography and traffic of the mining area mainly; The geographical position of the mine, field range of well; The meteorological condition of the mining area, general situation of earthquake intensity, the power and source of water; Characteristic of field quality of the
6、 well, coal seam, nature of coal general situation and hydro geological condition general situation, etc. It expound the fact separately mines open-ups by main shafts, Auxiliary shaft, waste rock well, level divide and exploit the divisions of person who adopt, person who adopt assign order and, every tunnel assign etc. equipment ventilating shaft the choices of position things. The ventilation design includes the choice of the ventilating system of mine mainly, Calculation, distribution,
