1、 本科生毕业设计说明书（毕业论文） 题 目：煤炭公司 3 煤层地下开采初 步设计 I 摘摘 要要 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。 本设计是在永智煤矿原始地质条件下作的矿井初步设计，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，以及专题采煤工作面瓦斯综 合治理等方面。 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

2、开拓分别论述了主井、副井位置选择、采区的划分、水平的划分以及开采顺序、 采区的布置及装备、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：关键词：矿井；开拓开采；通风；安全。 II ABSTRACT The coal field to the geography and varied geological conditions of coal, mining methods have varied.

3、Mine production, its 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 Yong Zhi Coal M

4、ine, This design 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 coal face comprehensive management of gas, etc. The field general situation of the w

5、ell 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 well

6、, 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, the who
