【正文】 1 摘 要 本設(shè)計(jì)礦井為 龍煤集團(tuán) 鶴 崗礦務(wù)局 益新煤礦四水平延伸設(shè)計(jì)，礦井設(shè)計(jì)產(chǎn)量 。 四水平 一共有 5 層可采煤層，分別為 3＃、 7＃、 8＃、 9＃、 11＃ 。 煤層總厚度為 米 ， 煤層工業(yè)牌號(hào)為焦煤，設(shè)計(jì)井田的可采儲(chǔ)量 ，服務(wù)年限為 101 年 。 本礦井設(shè)計(jì)采用以立井為主的多水平開(kāi)拓方式，劃分為四個(gè)水平，延伸后的四水平分為五個(gè)采區(qū)。 四水平投產(chǎn)采區(qū)為南二石門(mén) 3層采區(qū)，采用 單翼開(kāi)采，一個(gè)工作面達(dá)產(chǎn)，達(dá)產(chǎn)時(shí)采區(qū)個(gè)數(shù)為 一 個(gè)。 四水平煤層間距不大， 巷道 采用 聯(lián)合 布置。 設(shè)計(jì)確定四水平大巷煤炭運(yùn)輸選用皮帶 ， 四水平輔助運(yùn)輸采用 8噸防爆型蓄電池電機(jī)車(chē)牽引 3噸固定礦車(chē)運(yùn)輸 。 采用的采煤方法為走向長(zhǎng)壁采煤法，采煤工藝為綜采放頂煤工藝 ， 頂板處理方法為全部跨落法。 關(guān)鍵詞 ： 礦井設(shè)計(jì) 水平延伸 聯(lián)合開(kāi)拓 全套圖紙，加 153893706 2 Abstract The design of the mine in Hegang Mining Bureau Longmei new coal interests extended four level design, mine design output Mt / a, a total of four levels of a fivestorey coal seam, respectively 3, 7, 8, 9, 11, seam thickness of meters. Industrial grade coal for coke, coal mine design recoverable reserves of Mt, the service life of 101 years. The mine shaft design used mainly to the level of opening up more, divided into four levels, After the extension is divided into five four mining area. Four levels of operation for the Southern District Shihmen 3 2mining area, using singlewing, mining, production of a face, When production of mining area for a number. 4 level spacing little seam, a joint arrangement. Designed to determine the level of roadway four coal transport belt use four auxiliary transport level using eight tons of explosionproof motor vehicle traction battery 3 tons fixed tub transport, mining method used for longwall mining, coal mining technology for fully mechanized coal caving technology. Roof approach for the entire crossloading method. Key Phrase： Mine design standards in developing joint extension 3 目 錄 摘 要 ....................................................................................................................... 1 ABSTRACT ................................................................................................................ 2 緒 論 ......................................................................................................................... 7 第 1 章 井田概況及地質(zhì)特征 ............................................................................... 8 井田概況 .................................................................................................. 8 交通位置 ....................................................................................... 8 地形 地勢(shì) ................................................................................... 8 主要河流湖泊水庫(kù)溝塘的分布及地震史 ................................... 8 氣候 ............................................................................................... 8 附近工礦農(nóng)業(yè)概況及原料供應(yīng)情況 ........................................... 9 煤田開(kāi)發(fā)歷史及近況 ................................................................... 9 水電的供給情況 ........................................................................... 9 地質(zhì)特征 ................................................................................................ 10 礦區(qū)內(nèi)的地層情況 ..................................................................... 10 井田范圍內(nèi)和附近的主要地質(zhì)構(gòu)造 ......................................... 12 煤層賦存狀況及可采煤層特征 ................................................. 14 巖石性質(zhì) 厚度特征 ................................................................. 15 井田水文地質(zhì)情況 ..................................................................... 16 沼氣 煤塵及煤的自燃性 ......................................................... 18 煤質(zhì)牌號(hào)及用途 ......................................................................... 18 勘探程度及可靠性 ................................................................................ 19 第 2 章 井田境界 、 儲(chǔ)量 、服務(wù)年限 ................................................................. 20 4 井田境界 ............................................................................................... 20 井田周邊情況 ............................................................................. 20 . 井田境界確定的依據(jù) .................................................................. 20 井田未來(lái)發(fā)展 狀況 ..................................................................... 20 井田儲(chǔ)量 ............................................................................................... 20 井田儲(chǔ)量的計(jì)算 ......................................................................... 20 保安煤柱 ..................................................................................... 21 儲(chǔ)量計(jì)算的方法 ......................................................................... 21 儲(chǔ)量計(jì)算的評(píng)價(jià) ......................................................................... 22 礦井工作制度 生產(chǎn)能力 服務(wù)年限 ............................................... 22 礦井工作制度 ............................................................................. 22 礦井生產(chǎn)能力 ............................................................................. 22 礦井設(shè)計(jì)服務(wù)年限 ..................................................................... 22 第 3 章 井田開(kāi)拓 ................................................................................................. 23 概 述 .................................................................................................. 23 井田內(nèi)外及附近生產(chǎn)礦井開(kāi)拓方式概述 ................................. 23 影響本設(shè)計(jì)礦井開(kāi)拓方式的因素及具體情況 ......................... 23 確定井田開(kāi)拓方式的原則 ......................................................... 23 礦井開(kāi)拓方案的選擇 ........................................................................... 23 井硐形式和井口位置 ................................................................. 23 開(kāi)采水平數(shù)目和標(biāo)高 ................................................................. 24 開(kāi)拓巷道的布置 ......................................................................... 24 選定開(kāi)拓方案的系統(tǒng)描述 ................................................................... 26 井硐形式和數(shù)目 ......................................................................... 26 井
