畢業(yè)設(shè)計(jì)--采礦畢業(yè)設(shè)計(jì)畢業(yè)論文

摘要
     本設(shè)計(jì)是鐵法大興三礦300萬噸/年新井設(shè)計(jì)。結(jié)合大興三礦的具體條件，對大興三礦的地質(zhì)條件、賦存條件和其他各方面因素分析，通過經(jīng)濟(jì)比較確定了本礦采用立井開拓方式。單水平布置，布置了兩條巖石大巷，其中一條回風(fēng)大巷，另一條是運(yùn)輸大巷。煤層大巷分別用于回風(fēng)、帶區(qū)運(yùn)煤和進(jìn)風(fēng)行人。由于煤層平均傾角比較小，經(jīng)過分析比較確定了傾斜長壁采煤法。此方法巷道布置簡單，效率高，出煤快，比較合理。礦井通風(fēng)確定了中央并列式通風(fēng)方式，風(fēng)井采用抽出式通風(fēng)，滿足了該礦井的通風(fēng)要求。主井采用箕斗提升，可以滿足煤炭的提升要求。最后確定了排水、供電以及其他的部分的設(shè)計(jì)內(nèi)容。此設(shè)計(jì)符合相關(guān)的法律法規(guī)，達(dá)到國家要求安全生產(chǎn)的各項(xiàng)標(biāo)準(zhǔn)。

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
Key word: Vertical shaft； Single leve；incline long wall mining coal；central compound -like ventilation
