【正文】 區(qū)巷道布置; 采煤方法; 井下運(yùn)輸; 礦井提升; 礦井通風(fēng)與安全; 設(shè)計(jì)礦井基本技術(shù)經(jīng)濟(jì)指標(biāo)。 井田開(kāi)拓方式為立井單水平上下山開(kāi)拓。 井田工業(yè)儲(chǔ)量為 12246 萬(wàn) t,可采儲(chǔ)量為 8911 萬(wàn) t。翟鎮(zhèn)煤礦位于山東省泰安市管轄的新泰市境內(nèi),交通便利。 一般部分為翟鎮(zhèn)煤礦 。井田地質(zhì)條件較為簡(jiǎn)單。礦井瓦斯相對(duì)涌出量為 m3/t,絕對(duì)涌出量為 ,為瓦斯礦井。礦井年工作日為 330d,工作制度為 “三八 ”制。 關(guān)鍵詞: 立井;單水平;帶區(qū);中央并列式通風(fēng) ABSTRACT This design includes three parts: the general part, the special subject part and the translation part. The general part is a new design for Zhaizhen mine. Zhaizhen mine is located in Xintai which es within the jurisdiction of Tai’an in Shandong province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is ,the width is about , and the total area is fourth and the sixth are the main coal seams, and its dip angle is 5~15 degree. The thickness of the mine is about in all. The geologic structure of this coalfield is simple. The recoverable reserves of the coalfield are million tons,and the minable reserves are million tons. The designed productive capacity is million tons percent year, and the service life of the mine is years. The normal flow of the mine is 200m3 per hour and the max flow of the mine is 300 m3 per hour. The relative mine gas gush is m3/t and the absolute gush is m3/min, so it is a low gas mine. The mine is a single level in two shafts to develop. Te central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the ventilation mode of this mine is center juxtapose form. The “threeeight” working system is used in the Zhaizhen mine. It produces for 330 days a year. This design includes ten chapters: outline of the mine field geology。 layout of panels。 9. The ventilation and the safety operation of the mine。 Panel; Center juxtapose ventilation 中 國(guó)礦業(yè)大學(xué) 20xx 屆本科生畢業(yè)設(shè)計(jì) 第 3 頁(yè) 目 錄 一般部分 1 礦井概況與地質(zhì)特征 ................................................. 8 礦井概況 .............................................................................................................................. 8 地理位置與交通 ............................................................................................................ 8 地形地貌及水文情況 .................................................................................................... 8 氣候條件 ........................................................................................................................ 9 其它條件 ........................................................................................................................ 9 井田地質(zhì)特征 ...................................................................................................................... 9 地層 ................................................................................................................................ 9 地質(zhì)構(gòu)造 ...................................................................................................................... 10 水文地質(zhì) ...................................................................................................................... 10 煤層特征 .............................................................................................................................11 煤層 ...............................................................................................................................11 煤質(zhì)及用途 .................................................................................................................. 12 煤層開(kāi)采技術(shù)條件 ...................................................................................................... 14 2 井田境界和儲(chǔ)量 .................................................... 16 井田境界 ............................................................................................................................ 16 本井田邊界的演變過(guò)程 .............................................................................................. 16 井田境界 ...................................................................................................................... 16 井田工業(yè)儲(chǔ)量 .................................................................................................................... 17 儲(chǔ)量計(jì)算基礎(chǔ) .............................................................................................................. 17 井田勘探程度 .............................................................................................................. 17 礦井工業(yè)儲(chǔ)量計(jì)算 ...................................................................................................... 17 礦井設(shè)計(jì)儲(chǔ)量 .................................................................................................................... 19 永久煤柱損失量 .......................................................................................................... 19 礦井設(shè)計(jì)儲(chǔ)量 .............................................................................................................. 20 礦井可采儲(chǔ)量 .................................................................................................................... 20 工業(yè)廣場(chǎng)保護(hù)煤柱煤量 .............................................................................................. 20 主要井巷保護(hù)煤柱煤量 .............................................................................................. 21 礦井可采儲(chǔ)量 .............................................................................................................. 21 3 礦井工作制度、設(shè)計(jì)生產(chǎn)能力及服務(wù)年限 ................................ 23 礦井工作制度 .................................................................................................................... 23 礦井設(shè)計(jì)生產(chǎn)能力及服務(wù)年限 ........................................................................................ 23 確定依據(jù) ...................................................................................................................... 23 礦井設(shè)計(jì)生產(chǎn)能力 .................................................................................
