【正文】 河南理工大學(xué)本科畢業(yè)設(shè)計(jì)(論文) 摘要 I 畢業(yè)設(shè)計(jì) 開灤崔家煤礦礦井的初步設(shè)計(jì) 摘要 本設(shè)計(jì)是根據(jù)河北省開灤集團(tuán)崔家寨礦的實(shí)際情況對(duì)其 礦井 進(jìn)行的初步設(shè)計(jì)。設(shè)計(jì)的井田面積為 34 平方公里,礦井年產(chǎn) 180 萬(wàn)噸,井田內(nèi)煤層賦層較深,傾角不大,平均厚 ,瓦斯涌出量相對(duì)較小,礦井涌水量一般。 設(shè)計(jì)采用立井開拓方式,采用傾斜長(zhǎng)壁采煤方法,綜合機(jī)械化 一次采全高的回采工藝,用全部跨落法處理采空區(qū),主要對(duì)礦井開拓 、采煤方法, 礦井排水,礦井通風(fēng)以及安全技術(shù)措施 進(jìn)行了初步設(shè)計(jì),對(duì)礦井運(yùn)輸、通風(fēng)、排水等生產(chǎn)系統(tǒng)進(jìn)行了設(shè)備選型計(jì)算,對(duì)礦井各個(gè)生產(chǎn)系統(tǒng)的生產(chǎn)過程進(jìn)行 了描述,并對(duì)礦井各個(gè)生產(chǎn)系統(tǒng)和各生產(chǎn)環(huán)節(jié)之間的相互聯(lián)系和制約關(guān)系進(jìn)行了有關(guān)說明。在設(shè)計(jì)過程中,盡量采用先進(jìn)的技術(shù)和設(shè)備,礦井全部實(shí)現(xiàn)機(jī)械化,采用先進(jìn)技術(shù)和借鑒已實(shí)現(xiàn)高產(chǎn)高效現(xiàn)代化礦井的經(jīng)驗(yàn),實(shí)現(xiàn)一礦一面高產(chǎn)高效礦井從而達(dá)到良好的經(jīng)濟(jì)效益和社會(huì)效益。 關(guān)鍵詞: 開拓方式 采煤方法 礦井排水 礦井通風(fēng) 河南理工大學(xué)本科畢業(yè)設(shè)計(jì)(論文) 目錄 II Abstract This design is according to heibei kailuan group cui home village of actual situation to the preliminary design of the mines. Design of area of 34 square kilometers in laohutai mine field of 180 tons of coal mine, coal, the field of deep layer within assigned, little inclination thick on average, a m, gas flowvolume was relatively small, mine yield. Design uses vertical way, adopt strip type development, using tilt to longwall mining method, prehensive mechanized in one of the high technology, with all the grouting method across the fall of coal mine, and mine drainage, and mine ventilation and safety technical measures, the preliminary design of mine ventilation and drainage as transport, the production system, selection of equipment for each production calculation of mine production process system are described, and all of mine production system and the relationship between production and related instructions. Between In the design process, the use of advanced technology and equipment, mine, all realize mechanization by advanced technology and reference has realized high, realize the modernization of mine ore a side experience high yield and high efficiency and good economic benefit and social benefit. Keywords: Pioneering way Mining method Mine drainage Mine ventilation 河南理工大學(xué)本科畢業(yè)設(shè)計(jì)(論文) 目錄 III 目錄 前 言 ..................................................................................................... 1 1 井 田 概 況 ....................................................................................... 2 交通位置 ............................................................................................................ 2 地形地貌及水系 ................................................................................................ 2 氣象與地震 ........................................................................................................ 2 水源 .................................................................................................................... 3 電源 .................................................................................................................... 3 2 地 質(zhì) 特 征 ....................................................................................... 4 地層及地質(zhì)構(gòu)造 ................................................................................................ 4 地層 ............................................................................................................. 4 地質(zhì)構(gòu)造 ...................................................................................................... 5 煤層及煤質(zhì) ........................................................................................................ 5 煤層 ............................................................................................................. 5 煤質(zhì) ............................................................................................................. 6 煤層頂?shù)装迩闆r ........................................................................................... 6 瓦斯 ............................................................................................................. 6 煤塵爆炸性 .................................................................................................. 6 煤的自燃傾向 ............................................................................................... 6 地溫 ............................................................................................................. 6 水文地質(zhì)條件 .................................................................................................... 7 井田內(nèi)主要含水層 ........................................................................................ 7 主要隔水層 .................................................................................................. 7 地下水的補(bǔ)給、徑流及排泄條件 ................................................................... 8 井田水文地質(zhì)類型 ........................................................................................ 8 礦井涌水量 .................................................................................................. 9 河南理工大學(xué)本科畢業(yè)設(shè)計(jì)(論文) 目錄 IV 地質(zhì)勘探程度及存在的問題 ............................................................................ 9 3 井區(qū)設(shè)計(jì)概況 .....................................................................................10 井田境界 .......................................................................................................... 10 井田儲(chǔ)量 .......................................................................................................... 10 礦井工業(yè)儲(chǔ)量 .................................................................................................. 10 礦井設(shè)計(jì)儲(chǔ)量 .................................................................................................. 11 礦井工作制度 .................................................................................................. 12 礦井服務(wù)年限 .................................................................................................. 12 4 井田開拓 ...........................................................................................14 開拓方式選擇 ................................................................................................
