某铜铁矿500kta地下开采方案设计

武汉科技大学本科毕业设计摘要在现有国家相关矿山法规的前提下，结合湖北省大治市某铜铁矿矿区地质资料，对该矿进行500ktWa地下开采方案设计。分析处理矿山矿石品位，验证开采可行性：由技术经济比较，选择各方案：采用图表说明，分析概括计算、验证过程：整理相关技术要求，设计矿山各系统：运用计算分析，验证相关计算结果。主要内容：设计开采范围为-65m~305m,设计开采矿石矿量14965kt,矿山服务年限总产期为30年（包含2年基建期）；采用下盘竖井开拓方式，含主井1个、副井1个、风井1个，主井为箕斗井用于提升矿石，副井为罐笼井用于提升废石、人员、材料及设备：矿山采用上向进路充填法进行开采：设计矿区采用中央并列式通风方式，新鲜风流由副井流入，经各阶段工作面洗刷各水平后，由上一阶段回风巷道流至风井排出地表：井下排水方式为井底集中排水，中央水泵房、水仓设置在开采最低水平-305m阶段，各阶段地下水经由泄水井排入水仓后，由水泵泵送至地表排出：井下运输采用有轨、无轨联合运输，阶段运输采用电机车牵引矿车的方式运输，采场装矿采用铲运机出矿：区内地表布置有采矿工程正常生产的全套设施及工业场地、职工生活区，区内布置有公路用以与外部路网连通：设计根据矿山环保、安全及工业卫生相关规定，提出相应治理措施：计算矿山技术经济及经济概算，预计项目总投资25572.84万元，正常生产年年均利润总额7083.69万元/，正常生产年投资利润率27.70%，投资利税率41.53%,财务内部收益率13.01%，静态投资回收期6.14年（含建设期2年），动态投资回收期8.53年（含建设期2年），盈亏平衡点为25.76%，对矿山生产及辅助系统进行初步设计。基于目前矿山条件，通过理论计算校核，验证某铜铁矿500kt/开采开拓、提升、运输、通风、排水等系统均满足安全、生产相关要求，矿山企业技术经济效果合理。关键词：铜铁矿：地下开采：采矿方案设计：充填采矿法武汉科技大学本科毕业设计AbstractOn the premise of the existing national mining laws and regulations,combined with thegeological data of Tonglushan copper mine in Daye city,Hubei province,the 500kt/aunderground mining scheme was designed for this mine.Analyzed and treated the ore grade of mine,verified the feasibility of mining.From thetechnical and economic comparison,the scheme was chosen.Used charts to illustrate,analyzedand summarized the calculation and verification process.Collated related technicalrequirements and designed mine systems.Verified the relevant calculation results bycalculation analysis.Main contents:the designed mining range is-65m~-305m,the designed mining volume is6193kt,and the total production period of mine service life is 30 years(including two years ofinfrastructure construction period).Footwall shaft development method is adopted,including 1main shaft,I auxiliary shaft and I air shaft.The main shaft is skip shaft for lifting ore,and theauxiliary shaft is cage shaft for lifting waste rock,personnel,materials and equipment.Themine adopts the filling-up method.The design mining area adopts the central parallel ventilationmode.The fresh air flow flows into the auxiliary shaft,after washing the working face at eachlevel,the return air roadway flows to the surface of the air shaft at the previous level.Thedownhole drainage method is centralized drainage at the bottom of the shaft.The central waterpump room and sump are set at the lowest mining level,which is-305m level.The groundwaterin each level is discharged into the sump through the drainage well and then pumped to thesurface for discharge.The underground transportation adopts rail and trackless combinedtransportation,the transportation at levels adopts the mode of electric locomotive tractionharvard-car transportation,and the stope loading adopts the scraper to take out the ore.Acomplete set of facilities,industrial sites and workers'living areas for normal production ofmining projects are arranged on the surface of the area.A highway is arranged in the area tocommunicate with the external road network.According to mine environmental protection,safety and industrial hygiene related r
