#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。
Abstract
The design of Woxi Woxi pit mining area in Yuanling County in Hunan Province 82 km north-east, is located in Yuanling, Taoyuan County at the junction of two, it is a medium-sized state-owned enterprises and more metal, ore products primarily for gold, antimony , Tungsten ores.
The design is divided into eight parts, namely: (1) General (2) deposit in the occurrence of natural profile and raw data (3) deposits, (4) Development System (5) mining methods; (6) mine ventilation; (7) mining and upgrading transport, (8) topics: Xiangxi Gold mine Woxi Review of the mining methods. According to the Hang Hau Woxi specific deposit, geological conditions, conditions of deposit exploitation of the mining methods used for hydraulic roof pillar wall caving. Wo Hang Hau River to its design production capacity of 180,000 tons / year, the choice of the method of mining ore recovery, the loss rate, poverty rate are as follows: 95%, 4%, 5%. Ventilation way into the central wind out of the two wings of the wind-back, more than 16 middle of a pioneering system Woxi Hang Hau open up the original system, as the design of deep (16 middle section below) using double-blind inclined development, transport used cars, upgrade a Series car upgrade.
The design feature of the Western Hunan Gold Mine Woxi Review of gold mining method, first introduced nine kinds of mining methods and the development of mining technology and mining methods that the existin
