The general part is a new design of Lin nan cang Mine in Kailuan Group. It has ten chapters: the outline of the mine and coalfield geology, boundary and reserves, the designed annual production capacity, service life and working area, underground transportation, lifting, ventilation and safety, the economy and technology index of the mine. The Lin nan cang coal field lies in the YuTian city of Hebei province. The boundary of the mine runs km from west to east and from north to south on average. The total area of the mine is about km2. there are two available seams:9,12. They buryed stably and belonging to lesser pitching coal seam, with the average angle 20 degree. The industry reserves of the mine are 176 million tons and the useable 133 million tons. The average flow of the mine water is from 1170 m3/h. It is a lower gas mine. The coal dust have explosion hazard, and the seam has selfbustion tendency. The production annual capacity of Lin nancang mine is million tons, and it’s service life is years. There are 3 levels in the mine. The first development level located at the 450m, the second is –750m and the third is –900m. The minning method is fully mechanized along the coal bed strike. There is only one working face in the mine. The length of the face is 180m. Coal is transported by the bottom–dump mine car which capacity is 3t and dragged by 10 ton accumulator electrical engineering cars. The form of ventilation is the limitrophe to the coalfield’s center. The main content of the special subject part is Deep pressure and open pit mining. This paper analyzes coal mining Wells of pressure control, this paper expounds several key problems of deep pressure characteristic, the research progress of countermeasures. Finally pointed out in this field at mechanical problems. In order to adapt to the mine roadway by deep mining is decorated, strengthening optimization technology reform, reasonable supporting anization construction, and further improve the level and guarantee mining in stead of benefit maximization, realized. 華北科技學(xué)院畢業(yè)設(shè)計(jì)(論文) 第 3頁(yè) 共 155頁(yè) 目錄 一般部分 1 礦區(qū)概述及井田地質(zhì)特征 .......................................... 10 礦區(qū)概述 ................................................... 10 井田地質(zhì)特征 ............................................... 11 井田地質(zhì)構(gòu)造 .......................................... 11 煤系地層劃分及其特征 ................................. 12 井田水文地質(zhì) ......................................... 17 煤層特征 ................................................... 18 可采煤層情況 ......................................... 18 煤的物理性質(zhì) ......................................... 18 煤的圍巖特性 ......................................... 19 煤的特征 ............................................. 19 瓦斯和煤塵 ........................................... 21 2 井田境界及 儲(chǔ)量 .................................................. 22 井田境界 ................................................... 22 井田劃分依據(jù) ......................................... 22 井田境界確定 ......................................... 22 井田工業(yè)儲(chǔ)量的計(jì)算 ......................................... 22 井田地質(zhì)儲(chǔ)量 ......................................... 22 工業(yè)儲(chǔ)量的確定 ....................................... 23 井田可采儲(chǔ)量 ............................................... 23 永久煤柱煤量 ......................................... 23 礦井可采儲(chǔ)量計(jì)算 ..................................... 26 礦井儲(chǔ)量匯總表 ....................................... 26 3 礦井工作制度和設(shè)計(jì)生產(chǎn)能力 ...................................... 27 礦井工作制度 ............................................... 27 礦井設(shè)計(jì)生產(chǎn)能力及服務(wù)年限 ................................. 27 4 井田開(kāi)拓 ........................................................ 30 華北科技學(xué)院畢業(yè)設(shè)計(jì)(論文) 第 4頁(yè) 共 155頁(yè) 井田開(kāi)拓的基本問(wèn)題 ......................................... 30 確定井筒 的形式、數(shù)目、配置 ........................... 30 確定工業(yè)廣場(chǎng)及井口位置 ............................... 31 確定開(kāi)采水平和階段高度 ............................... 32 開(kāi)采水 平布置及井底車場(chǎng)的選型 ......................... 33 采區(qū)劃分及其布置 ..................................... 34 井田開(kāi)拓設(shè)計(jì)方案比較 ....................................... 35 開(kāi)拓方案技術(shù)比 較 ..................................... 35 經(jīng)濟(jì)比較 ............................................. 38 綜合比較 ............................................. 40 礦井基本巷道 ............................................... 40 井筒 ................................................. 40 井底車場(chǎng) ............................................. 43 主要開(kāi)拓巷道 ......................................... 45 5 采區(qū)巷道布置 .................................................... 50 煤層地質(zhì)特征 ............................................... 50 可采煤層情況 ......................................... 50 煤種及煤質(zhì)變化 ....................................... 50 各煤層頂?shù)装鍘r性 ..................................... 51 煤塵和瓦斯 ............................................... 51 采區(qū)巷道布置及 生產(chǎn)系統(tǒng) ..................................... 51 確定采區(qū)走向長(zhǎng)度 ..................................... 51 確定區(qū)段斜長(zhǎng)和區(qū)段數(shù)目 ............................... 52 煤柱尺寸的確定 ....................................... 52 采區(qū)上下山的布置 ..................................... 52 區(qū)段平巷的布置 ....................................... 53 聯(lián)絡(luò)巷道的布置 ....................................... 53 采區(qū)運(yùn)輸、通風(fēng)運(yùn)料等系統(tǒng)的確定 ....................... 53 采區(qū)車場(chǎng)設(shè)計(jì) ............................................... 55 采區(qū)上部車場(chǎng)形式的選擇 ............................... 55 華北科技學(xué)院畢業(yè)設(shè)計(jì)(論文) 第 5頁(yè) 共 155頁(yè) 采取中部車場(chǎng)形式的選擇 ............................... 56 采區(qū)下部車場(chǎng)的選擇及設(shè)計(jì) ............................
