畢節(jié)學(xué)院論文(設(shè)計(jì)) 第 I 頁(yè) 摘 要 貴州省畢節(jié)市織金縣以那鎮(zhèn)寶山煤礦, 織金縣寶山煤礦位于織金縣以那鎮(zhèn)南東,其西部邊界緊靠以那鎮(zhèn), 至貴州省織金縣城 30km,屬織金縣以那鎮(zhèn)所轄。 礦區(qū)邊界為一不規(guī)則的多邊形 , 東界至多吉河,北界至 F1 斷層。 井田走向 平均 寬 約 , 傾向 平均長(zhǎng)約 ,面積 。 區(qū)內(nèi)煤炭資源豐富,煤質(zhì)較好,氣候條件適宜。 礦區(qū)內(nèi)交通以公路為主,織金至納雍、水城的公路 ( S307) 從礦區(qū)南部經(jīng)過(guò),以那鎮(zhèn) 至 織金 30km,至 織金火電廠(八步鎮(zhèn)) 25km,至 水城 123km, 至 貴陽(yáng) 215km, 從織金至貴昆線黃桶站的鐵路已經(jīng)開始運(yùn)營(yíng), 交通較為方便 。礦區(qū)內(nèi)礦產(chǎn)豐富,除煤外,還有粘土、石灰?guī)r、鋁土質(zhì)泥巖和鋁土巖、稀散元素及煤層氣等。粘土可燒制磚、瓦、鉆探用泥漿及其它民用;石灰?guī)r廣泛分布,當(dāng)?shù)剞r(nóng)民用之作燒石灰原料及建筑石料,當(dāng)?shù)厮鄰S亦用之作原材料。稀散元素:礦區(qū)內(nèi)各稀散元素含量較低,均達(dá)不到最低工業(yè)品位,不具開采價(jià)值。鋁土質(zhì)泥巖和鋁土巖:巖層主要位于含煤地層底部,全礦區(qū)發(fā)育,一般厚度約為 。巖質(zhì)不純,未進(jìn)行專門采樣。 礦井設(shè)計(jì)開采煤層為井田內(nèi)的 C8 煤層,煤的平均厚度分 別為 ;傾角為 9176?!?3176。,平均為 11176。礦井按照煤與瓦斯突出、煤層自燃和煤塵具有爆炸性設(shè)計(jì)。井田的走向長(zhǎng)平均為 ,傾斜長(zhǎng)平均為 ,井田面積約為 ;井田內(nèi)的工業(yè)儲(chǔ)量約為 3663 萬(wàn)噸,可采儲(chǔ)量為 3663 萬(wàn) t;礦井的設(shè)計(jì)年產(chǎn)量為 45萬(wàn) t/a,設(shè)計(jì)服務(wù)年限為 55a;工作面作業(yè)方式采用的是“兩班半采煤,半班準(zhǔn)備”的工作方式。設(shè)計(jì)井田內(nèi)無(wú)大的斷層和構(gòu)造,對(duì)礦井的正常生產(chǎn)無(wú)影響,礦井按高瓦斯礦井設(shè)計(jì)。井田內(nèi)采用反斜井單水平上、下山開拓方式,沿井田的傾斜方向,將井田劃分成二個(gè)階段,共 18 個(gè)區(qū)段進(jìn)行開采。根據(jù)井田內(nèi)無(wú)大的斷層和構(gòu)造特點(diǎn),準(zhǔn)備方式為上下山采區(qū)準(zhǔn)備,采區(qū)內(nèi)為單層準(zhǔn)備。 礦井的采煤方法采用的是單一走向長(zhǎng)壁后退式采煤法,回采工藝為綜合機(jī)械化采煤。井下煤炭主要采用皮帶運(yùn)輸機(jī)運(yùn)輸,材料和矸石等采用礦用電機(jī)車和礦車運(yùn)輸。 通風(fēng)方式采用中央邊界抽出式通風(fēng),選用礦用隔爆軸流式通風(fēng)機(jī),采區(qū)進(jìn)風(fēng)由副斜井進(jìn)風(fēng),主斜井輔助進(jìn)風(fēng)。由于本礦井是高瓦斯礦井,所以采用三條上下山,運(yùn)輸上山采用的是獨(dú)立通風(fēng)。運(yùn)輸上山采用的是膠帶運(yùn)輸,主斜井采用的是“機(jī)軌合一”運(yùn)輸方式;軌道上山布置雙軌道,車場(chǎng)均為甩車場(chǎng) 畢節(jié)學(xué)院論文(設(shè)計(jì)) 第 II 頁(yè) Abstract Pick a song to Zhijin county guizhou province bijie city in the township of baoshan mine, zhijin county, baoshan mine located in zhijin county in south east of the town, close to the town, the west boundary to guizhou zhijin county town 30 km, belong to zhijin county to the town. Mining area boundary is an irregular polygon, the east side to the edge, river, the north side to the F1 fault. Means to the average is about km wide, tend to be an average of about km long, covers an area of km178。. The rich coal resources, coal quality is good, suitable climatic conditions. Traffic is given priority to with road in mining area, zhijin to harmony, south shuicheng road (S307) from mining through, to the town to 30 km, zhijin to zhijin coalfired power plants (town) in eight steps 25 km, and the city 123 km, to guiyang 215 km, from zhijin to the railway line is yellow barrel station began operations, transportation is convenient. Mining in the mine is rich, in addition to coal, clay, limestone, bauxite and bauxitic mudstone, the scattered elements and coalbed methane, etc. Clay to fired brick, tile, drilling mud and other civilian。 Limestone widely distributed, local farmers use burned lime raw materials and building stone, a local cement plant also use raw materials. Scattered elements: the scattered elements content in the mine is low, all can not meet the minimum industrial grade, no mercial value. Bauxitic mudstone and bauxite, rock is mainly located at the base of the coalbearing strata, the whole mining area development, the general thickness is about m. Rock is not pure, not for sampling. C8 in coal of mining coal seam in coal mine design for the field, the average thickness of coal were m。 Inclination to 9 176。 ~ 13 176。, an average of 11 176。. According to the coal and gas outburst mine, the coal seam spontaneous bustion and coal dust explosive design. Tilt field towards an average of km long, on average, km long, field area of km2。 Within the field of industrial reserves of about million tons, the recoverable reserves of million t。 Mine design annual production capacity of 450000 t/a, the design length of service is a 55。 Working practices USES is two and a half class half coal mining, class preparation way of working. No big fault in the design field and structure, and can not 畢節(jié)學(xué)院論文(設(shè)計(jì)) 第 III 頁(yè) influence the normal production of mine, mine gas mine design. By reverse slope field within a single level, pioneering way down, along the tilt direction of mining field, mining field was divided into two stages, a total of 18 sections for mining. According to there is no big fault in the mining field and tectonic characteristics, the preparation way to climb the mountain for the first mining, mining for single layer. Mine coal mining methods is a single to longwall retreating mining method, stoping technology for the prehensive mechanized coal mining. Underground coal mainly adopts belt conveyor transport, materials and waste rock, mining electric lootive and car transport. Use a central boundary drawertype ventilation ventilation way, choose mine explosionproof axial flow fan, mining the wind by the auxiliary slope into the wind, the main auxiliary inclined well into the wind. Because the mine is gas mine, so use to climb the mountain three, transportation USES independent ventilation up to the mountain. Transport up USES a tape transport, inclined well of the main use is the mode of transportation of the unity of machine rail。 Orbit up the mountain and decorate a dual track, yard to uncouple field. 畢節(jié)學(xué)院論文(設(shè)計(jì)) 第 IV 頁(yè) 前 言 本次設(shè)計(jì)主要是考察自己在校期間所掌握專業(yè)知識(shí)的程度 ,通過(guò)設(shè)計(jì)可以使自己加深對(duì)專業(yè)知識(shí)的理解 ,彌補(bǔ)過(guò)去在學(xué)習(xí)中的不足 ,同時(shí)也為自己即將走上工作崗位打下堅(jiān)實(shí)的基礎(chǔ)。 本設(shè)計(jì)是以寶山礦井所收集的地質(zhì)資料作為基礎(chǔ)資料 ,煤層底板等高線圖,煤層綜合柱狀圖等圖件,以及地質(zhì)資料。查閱參考資料有煤礦開采學(xué)、礦山電工學(xué)、采礦設(shè)計(jì)手冊(cè)、礦山壓力及控制等參考資料。 礦井設(shè)計(jì)包括井田開拓、采區(qū)準(zhǔn)備和采煤方法,以及巷道掘進(jìn)、礦井提升、運(yùn)輸、通風(fēng)、排水、動(dòng)力供應(yīng)等各個(gè)生產(chǎn)系統(tǒng),礦井開采設(shè)計(jì)主要應(yīng)解決井田開采煤技術(shù)方案和確定各 項(xiàng)開采參數(shù),如確定井田的開拓方式、新水平開拓、延深方案、采準(zhǔn)巷道布置及生產(chǎn)系統(tǒng),選擇采煤方法,確定階段垂高、采區(qū)走向長(zhǎng)度、采煤工作面長(zhǎng)度等等。所選擇的方案及參數(shù)必須在技術(shù)上優(yōu)越,經(jīng)濟(jì)上合理,安全上可靠。 為此,我們?cè)谠O(shè)計(jì)時(shí)應(yīng)遵守以下基本原則: 第一,礦井設(shè)計(jì)必須貫徹國(guó)民經(jīng)濟(jì)建設(shè)有關(guān)方針政策,特別是煤炭工業(yè)的各項(xiàng)具體政策,應(yīng)有全局觀點(diǎn)。 第二點(diǎn),礦井設(shè)計(jì)應(yīng)在立足國(guó)情的前提下,滿足技術(shù)上先進(jìn),經(jīng)濟(jì)上合理,安全可靠適用,并要為礦井發(fā)展留有余地。在目前,還應(yīng)特別注意提高經(jīng)濟(jì)效益、社會(huì)效益和環(huán)境效益,以取得較好的綜合 業(yè)績(jī)。 第三點(diǎn),在設(shè)計(jì)中,應(yīng)理論聯(lián)系實(shí)際,盡量運(yùn)用所學(xué)的科學(xué)技術(shù)知識(shí),應(yīng)拓寬思路,在不違反國(guó)家方針政策和技術(shù)規(guī)范的前提下,大膽采用國(guó)內(nèi)外先進(jìn)技術(shù)和設(shè)計(jì)方法。 最后,設(shè)計(jì)應(yīng)按有關(guān)部門指定的技術(shù)范圍、規(guī)程、標(biāo)準(zhǔn)系列等進(jìn)行。設(shè)備選型上要注意以標(biāo)準(zhǔn)化、通用化、系列化并在國(guó)內(nèi)成批量供應(yīng)的型號(hào)為依據(jù),新技術(shù)新工藝應(yīng)以國(guó)內(nèi)試驗(yàn)成功并經(jīng)過(guò)鑒定批準(zhǔn)的方能采用。 畢節(jié)學(xué)院論文(設(shè)計(jì)) 第 1 頁(yè) 第一章 礦井建設(shè)及基本條件 第一節(jié) 井田概況 一、井田位置及交通 (一 )、位置 織金縣寶山煤礦位于織金縣以那鎮(zhèn)南東,其西部邊界緊靠以那鎮(zhèn), 至貴州省織金縣城 30km,屬 織金縣以那鎮(zhèn)所轄。 礦區(qū)邊界為
