【正文】 前 言礦業(yè)六礦井初步設(shè)計(jì)說(shuō)明書(shū)摘 要：本次設(shè)計(jì)的沃溪礦區(qū)沃溪坑口位于沅陵縣城北東 82km 處，地處沅陵、桃源二縣交界處，它是一個(gè)中型的多金屬國(guó)有企業(yè)，其礦石成品主要為金、銻、鎢礦石。本設(shè)計(jì)共分為 8 個(gè)部分，它們分別是：（1）總論；（2）礦床賦存地區(qū)的自然概況及原始資料（3）礦床地質(zhì)；（4）開(kāi)拓系統(tǒng)；（5）采礦方法；（6）礦井通風(fēng)；（7）礦山提升和運(yùn)輸；（8）專題：湘西金礦沃溪礦區(qū)沃溪坑口采礦方法述評(píng)。根據(jù)大沃溪坑口具體的礦床地質(zhì)條件、礦床開(kāi)采條件采礦方法采用水壓支柱護(hù)頂壁式崩落法。其沃溪坑口擬設(shè)計(jì)的生產(chǎn)能力為 18 萬(wàn)噸/年，選用該采礦方法的礦石回收率、損失率、貧化率分別為：95%、4%、5%。通風(fēng)方式采用中央進(jìn)風(fēng)兩翼抽出式回風(fēng)，16 中段以上開(kāi)拓系統(tǒng)采用沃溪坑口原來(lái)的開(kāi)拓系統(tǒng)，做為本設(shè)計(jì)深部（16 中段以下）采用雙盲斜井開(kāi)拓，運(yùn)輸采用礦車，提升采用串車提升。此次設(shè)計(jì)專題部分湘西金礦沃溪金礦采礦方法述評(píng)，首先是介紹 9 種采礦方法發(fā)展現(xiàn)狀及回采工藝，然后指出采礦方法存在的問(wèn)題，再根據(jù)存在的問(wèn)題進(jìn)行合理選用采礦方法和采礦方法改進(jìn)途徑進(jìn)行述評(píng)。關(guān)鍵詞：礦床地質(zhì)；雙盲斜井開(kāi)拓系統(tǒng)；水壓支柱護(hù)頂壁式崩落采礦法；礦井通風(fēng)；礦山提升與運(yùn)輸；采礦方法述評(píng)。Abstract The design of Woxi Woxi pit mining area in Yuanling County in Hunan Province 82 km northeast, is located in Yuanling, Taoyuan County at the junction of two, it is a mediumsized stateowned 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 windback, 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 doubleblind 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 existing problems, then under the existing problems of rational use of mining methods and mining method Commentary on ways to improve. Key words: Geological。 inclined pioneering doubleblind system。 pressure pillar for the top wall caving。 mine ventilation。 mine upgrade and transport。 Review of the mining methods.目 錄第 1 章 總 論 ..............................................................................................................1 設(shè)計(jì)指導(dǎo)思想 .................................................................................................................................1 設(shè)計(jì)的基本要求 .............................................................................................................................11. 3 設(shè)計(jì)依據(jù) ........................................................................................................................................1 沃溪礦區(qū)的整體概況 .....................................................................................................................2 資源條件 .................................................................................................................................2 外部運(yùn)輸、供水、供電條件 .................................................................................................2 設(shè)計(jì)規(guī)模 .................................................................................................................................3 服務(wù)年限 .................................................................................................................................3 開(kāi)采方法 ..................................................................................................................................3 產(chǎn)品方案 .................................................................................................................................3 企業(yè)組成、開(kāi)采工藝及“三廢”的處理、綜合利用 .................................................................3 企業(yè)組成 .................................................................................................................................3 “三廢”的處理和綜合利用 ..................................................................................................4 開(kāi)采工藝主要設(shè)計(jì)方案的比較和選擇 .................................................................................4 重要技術(shù)經(jīng)濟(jì)指標(biāo) .........................................................................................................................4 作業(yè)成本 .................................................................................................................................4 勞動(dòng)定員 ...............................................................................................................................51. 7 需要說(shuō)明的問(wèn)題及建議 ................................................................................................................5第 2 章礦床賦存地區(qū)的自然概況及原始資料 ............................................................7 .............................................................................................................7 位置與交通 ..............................................................................................................................7 自然經(jīng)濟(jì)概況 ..........................................................................................................................8 礦區(qū)附屬設(shè)施 .................................................................................................................................8 外部運(yùn)輸、供水、供電條件 .........................................................................................................9 開(kāi)采情況 .........................................................................................................................................9 礦山的工作制度、工資制度、勞動(dòng)組織形式 .............................................................................9 礦區(qū)開(kāi)采情況及種類、銷售情況、市場(chǎng)分析及對(duì)發(fā)展國(guó)民經(jīng)濟(jì)的意義 ...............................10 礦區(qū)開(kāi)采情況及產(chǎn)品種類 .................................................................
