矿主井井筒施工组织设计 摘要 本设计是根据 矿的实际情况对其矿井进行的主井施工组织设计，设计生产能力为400万T/a。瓦斯涌出量相对较大，矿井涌水量一般。 设计采用主井表土段采用冻结法施工，基岩段采用钻爆法施工，主要对矿井开拓、、采煤方法，矿井排水，矿井通风以及安全技术措施进行了初步设计，对矿井运输、通风、排水等生产系统进行了设备选型计算，对矿井各个生产系统的生产过程进行了描述，并对矿井各个生产系统和各生产环节之间的相互联系和制约关系进行了有关说明。在设计过程中，尽量采用先进的技术和设备，矿井全部实现机械化，采用先进技术和借鉴已实现高产高效现代化矿井的经验，实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。 关键词：冻结法凿井, 基岩段爆破,瓦斯,文明施工 CONSTRUCTION ORGANIZATION DESIGN OF ZHUJI WEST MAIN SHAFT ABSTRACT This design is according to Anhui Wanbei Coal Group zhuji west of actual situation to the preliminary design of the mines. The designed annual production capacity of it is 4 million tons. Gas emission is relatively large, mine water is generally. The design uses a the topsoil segment of the main shaft construction of the freezing method, bedrock section with the construction of the drilling and blasting method and mine drainage, and mine ventilation and safety technical measures, the preliminary design of mine ventilation and drainage as transport, the production system, selection of equipment for each production calculation of mine production process system are described, and all of mine production system and the relationship between production and related instructions. Between In the design process, the use of advanced technology and equipment, mine, all realize mechanization by advanced technology and reference has realized high, realize the modernization of mine ore a side experience high yield and high efficiency and good economic benefit and social benefit.
