中段以上開拓系統(tǒng)采用沃溪坑口原來的開拓系統(tǒng)，做為本設(shè)計(jì)深部（16 中段以下）采用雙盲斜井開拓，運(yùn)輸采用礦車，提升采用串車提升。根據(jù)大沃溪坑口具體的礦床地質(zhì)條件、礦床開采條件采礦方法采用水壓支柱護(hù)頂壁式崩落法。前 言礦業(yè)六礦井初步設(shè)計(jì)說明書摘 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)。其沃溪坑口擬設(shè)計(jì)的生產(chǎn)能力為 18 萬噸/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%。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題，再根據(jù)存在的問題進(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)。Abstract The
