采矿毕业设计(论文+CAD图纸)

摘要

     本设计是铁法大兴三矿300万吨/年新井设计。结合大兴三矿的具体条件,对大兴三矿的地质条件、赋存条件和其他各方面因素分析,通过经济比较确定了本矿采用立井开拓方式。单水平布置,布置了两条岩石大巷,其中一条回风大巷,另一条是运输大巷。煤层大巷分别用于回风、带区运煤和进风行人。由于煤层平均倾角比较小,经过分析比较确定了倾斜长壁采煤法。此方法巷道布置简单,效率高,出煤快,比较合理。矿井通风确定了中央并列式通风方式,风井采用抽出式通风,满足了该矿井的通风要求。主井采用箕斗提升,可以满足煤炭的提升要求。最后确定了排水、供电以及其他的部分的设计内容。此设计符合相关的法律法规,达到国家要求安全生产的各项标准。

Abstract

The design of the iron ore deposits Daxing 3 million tons / year of new wells design. Daxing mine with three specific conditions, the Daxing Mine geological conditions, storage conditions and other factors, identified through economic comparison of the mine shaft using pioneering approach. Single-level layout, layout of the two rock roadway, which winds back to a main roadway, and the other one is transportation roadway. Seam roadway were used to the wind, to bring the district into coal and popular person. Because the average coal seam inclination is relatively small, determined through the analysis and comparison of the tilt longwall mining method. This method roadway layout simple, high efficiency, coal out fast, more reasonable. Mine ventilation identified alongside the central ventilation, ventilation shaft ventilation extract used to meet the requirements of the ventilation shaft. Skip the main shaft used to upgrade and meet the demands of coal upgrading. Finalization of the drainage, electricity and other parts of the design elements. This design comply with the relevant laws and regulations, and meet the national security requirements of the standard production
