1、摘要 I 摘 要 本设计进行的是荣达煤矿 9#煤层的矿井设计。根据设计要求，井田的工 业资源储量为 349.35Mt，可采储量为 276.04Mt，矿井设计生产能力为 3Mt/a， 矿井服务年限为 66a。划分两水平，均采用上山开采，井田走向长 4.8km，倾 斜长 4.4km，煤层平均倾角 13 0，属于缓倾斜煤层。工作制度为：矿井年工作 日 330d，每天四班作业，三班生产，一班准备及检修，每班工作 6h，矿井每 昼夜净提升时间 18h。矿井采用立井两水平开拓，划分四个采区，水平标高为 -700m、-350m。矿井采用走向长壁综合机械化一次采全高放顶煤采煤法。矿 井通风方式为两翼对角式，通
2、风方法为抽出式，采区通风方式为单巷式，上 行通风。本设计对矿井初期的需风量进行了计算与分配。 关键词：关键词：荣达煤矿；开拓设计；通风设计；对角式通风；通风阻力 Abstract II Abstract The design of the coal mine Rongda 9# coal seam mine design. According to design requirements, Its reserves of 349.35million tons of industrial resources, recoverable reserves of 267.04million tons,
3、 mine design capacity of 3 million t / a, the service life of mine for 66 years. The coal mine is divided into two levels. The way to explort with adopt the mountain mining, the long of the coal mine is 4.8Km and inclined long is 4.4Km.Average Angle of coal seam is 13, so it belongs to the slowly in
4、clined coal seam. Work system is: mine years working 330d, operating four shifts a day, three classes of production, preparation and maintenance of a group, class work 6h, the net raise mine every day and night time 18h. Multi-level mine shaft two levels of development and divided into four mining a
5、rea. the level of elevation-700m,-350 m. Mine used to all the cross-mechanized longwall all high Caving mining method down in one times. Mine ventilation for the two wings of the roles, methods for the exhaust ventilation, mining area of ventilation for the A back into two -style, up ventilation. Th
6、e design of the mine air volume required for the initial calculation and distribution.
