l 湘潭大学 毕业设计说明书 题 目： 小英田铁合金与工业用硅硅石矿初步设计 学 院： 专 业： 学 号： 姓 名： 指导教师： 完成日期： 2013.05.20 摘 要 茶陵县小英田矿区铁合金与工业硅用硅石矿位于茶陵县城北直距约27km，属茶陵县巴团乡管辖。矿区内没有发现断层，褶皱等影响开采的地质构造，地质构造简单。矿脉走向北东~西南，倾向290°，倾角60°，走向长约为450m,平均厚度6m。 根据《储量报告》圈定范围的资源和矿床赋存条件，产品需求等情况,拟定设计生产规模定为3万吨/年，矿山服务年限10年。矿山采用露天开采方式，公路开拓、汽车运输方案，由上至下水平台阶分层开采，中深孔爆破、挖掘机装载的采矿方式。 关键字：硅石矿 露天开采 台阶分层 中深孔爆破 ABSTRACT XIAO YING TIAN of Chaling County iron alloy and industrial silicon using silica mine located in the north of Chaling County straight from about 27km, under the jurisdiction of Chaling County township is ba group. Mining surface elevation changes greatly, the highest mining elevation is +630m, the minimum mining elevation +580m. Did not find fault within the mining area, geological structure mining fold effect, simple geological structure. Quartz vein, to the North East, southwest, inclination angle of 60 °, 290 °, to a length of about 450m, the average thickness of 6m. The main wall rock alteration zone include silicification, hornfels, albite, sericite and epidotization, wherein sericitization, silicification, epidotization development near fault belts. According to the report reserves delineation of resources and ore occurrence conditions, product demand, production scale is 30000 tons / year. The service life of mine for 10 years. Mine by open-pit mining, highway development, automobile transportation solutions, from top to bottom level bench mining, blasting, loading of the mining excavator. Keywords: deep-hole blasting in open-pit mining bench in silica. 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc353807506 第一章 矿区概况及地质特征 PAGEREF _Toc353807506 \h 8 HYPERLINK \l _Toc353807507 第一节 矿区概况 PAGEREF _Toc353807507 \h 8 HYPERLINK \l _Toc353807508 1.1.1 位置与交通 PAGEREF _Toc353807508 \h 8 HYPERLINK \l _Toc353807509 1.1.2 自然地理条件 PAGEREF _Toc353807509 \h 8 HYPERLINK \l _Toc353807510 1.1.3 经济概况 PAGEREF _To
