摘要 铁矿石是我国冶金工业的基本原料，在我国国民经济中占有重要地位。建国以来，采矿事业取得了巨大成就，铁矿石产量持续增长，生产技术水平不断提高，安全生产条件逐步改善。矿业经济对我国的国民经济和社会的发展发挥了重要。但是在我国金属矿山中存在着一些不合理的现象，例如，资源浪费严重、采矿方法不科学、环境治理落后等。本次铁矿设计年产量万t/a，设计开采矿量万t。设计详细介绍了地质情况，包括总论、矿山地质、矿床开拓、中段运输、矿山基建、采矿方法、矿井提升、矿井通风。设计还引用类似矿山生产经验，力争使矿山企业达到经济效益最大化。 关键词：阶段矿房法，矿床开拓，通风系统，提升系统。Abstract The iron ore is the basic material of metallurgical industry in our country, occupying important position in our national economy. Since the foundation of our country,the mining indestry has made a enormous achievement, the output of iron ore and the level of producing increases continuously, and the safe working condition is also improving progressively . It is well known that the economy of mining industry plays an important part in our country. But there are some unreasonable phenomenas in the metal mine of our country, for example the resource wastes seriously , developing method is not properble , and environmental improvement is not very good.etc. The annual production of the design is 200,000t/a , the reserve is 4050,000t. It introduces the detail geological situation and includes introduction , mine geology , mineral deposit developing , midsection transport , mine construction , mine method , mine promoting and mine ventilation. It also quotes some similar mine experience, in order to make the producing reach the most great economic benefit. Keyword: Block stoping, Mine development, Ventilation system, Hoisting system. 目录 引言 1 1 综述 2 1.1矿区概貌 2 1.2 矿山企业主要产品，国民经济中的地位 3 1.3设计任务 4 1.4矿山主要生产过程概述 4 1.5开采设计的主要技术经济指标 5 2 矿山地质 6 2.1矿区自然地理概况 6 2.2矿床地质 6 2.3水文地质 8 2.4矿石储量、质量及计算 8 3 矿床开拓 10 3.1矿山建设现状 10 3.2矿山年产量验证 10 3.3开拓方法 12 4 中段运输 15 4.1矿床开采顺序 15 4.2中段运输水平线路设计 15 5 矿山基建工程 18 5.1主井 18 5.2风井 22 5.3 石门及运输平巷 22 5.4井底车场 30 5.5基建工程量 37 6 采矿方法 45 6.1开采技术条件 45 6.2采矿方法选择 46 6.3矿块采准切割工程 48 6.4凿岩爆破 48 6.5矿柱回采及采空区处理 51 6.6采准、切割及回采计算 51 6.7采矿方法主要技术经济指标 55 7 矿井提升 57 7.1主井提升方式及系统选择 57 7.2矿井提升设备的选择 57 8 矿井通风 64 8.1矿井通风系统及通风方式 64 8.2全矿总风量计算 64 8.3全矿总风压计算 66 8.4选择通风设备 67 9 技术经济 70 9.1基建井巷
