1、前言#矿业六矿井初步设计说明书摘要:本次设计的沃溪矿区沃溪坑口位于#沅陵县城北东82km处,地处沅陵、桃源二县交界处,它是一个中型的多金属国有企业,其矿石成品主要为金、锑、钨矿石。本设计共分为8个部分,它们分别是:(1)总论;(2)矿床赋存地区的自然概况及原始资料(3)矿床地质;(4)开拓系统;(5)采矿方法;(6)矿井通风;(7)矿山提升和运输;(8)专题:湘西金矿沃溪矿区沃溪坑口采矿方法述评。根据大沃溪坑口具体的矿床地质条件、矿床开采条件采矿方法采用水压支柱护顶壁式崩落法。其沃溪坑口拟设计的生产能力为18万吨/年,选用该采矿方法的矿石回收率、损失率、贫化率
2、分别为:95%、4%、5%。通风方式采用中央进风两翼抽出式回风,16中段以上开拓系统采用沃溪坑口原来的开拓系统,做为本设计深部(16中段以下)采用双盲斜井开拓,运输采用矿车,提升采用串车提升。此次设计专题部分湘西金矿沃溪金矿采矿方法述评,首先是介绍9种采矿方法发展现状及回采工艺,然后指出采矿方法存在的问题,再根据存在的问题进行合理选用采矿方法和采矿方法改进途径进行述评。关键词:矿床地质;双盲斜井开拓系统;水压支柱护顶壁式崩落采矿法;矿井通风;矿山提升与运输;采矿方法述评。AbstractThedesignofWoxiWoxipitminingareainYua
