采礦工程畢業(yè)設計論文-雞西礦業(yè)集團小恒山煤礦18mta新井設計[2](已修改)

　

【正文】 1 摘 要 本設計礦井為雞西礦業(yè)集團小恒山煤礦 ，本井田內共有可采煤層 4 層 ,分別為 3上、 3下、 6A 和 23。煤層總厚度為 ，平均厚度 左右。均為 1/3 焦煤，主要用于煉焦和工業(yè)用煤。井田平均走向長 4400m，平均傾斜長 5000m，煤層賦存深度 +150m— 700m，主要地質構造為單斜和斷層，煤層平均傾角 11176。，屬緩傾斜煤層。 本設計礦井工業(yè)儲量 ，可采儲量 ，服務年限 64a。由于井田傾斜長度較大，且為緩傾斜煤層，確定采用傾斜長壁后退式 開采，分為 2個開采水平，水平標高分別為 60m 和 450m，均采用上下山開采，工作面全部采用綜合機械化采煤。 關鍵詞 : 緩傾斜煤層；傾斜長壁采煤法；綜合機械化采煤 全套圖紙，加 153893706 2 Abstract This design mine pit for the Jixi mining industry group Xiaohengshan coal mine ， in this well field altogether has may pick coal bed 4， respectively is on under 3A and 23.Coal bed total thickness is ， about average 。 Is 1/3 coking coal，mainly uses in the coking and the industrial used well field equally moves towards long 4400m， medium bank long 5000m， the coal bed tax saves depth +150m— 700m， the main geologic structure for the monocline and the fault, the coal bed average inclination angle 11176。 , is Slowly inclines the coal bed. This design mine pit mercial production ， recoverable resources ， service life 64 years。 Because the well field inclinesthe length to be bigger, also for Slowly inclines the coal bed， determineduses inclines long wall backlash type mining, divides into 2 mininglevels, the horizontal elevation respectively is 60m and 450m, useson descends a mountain mining, the working surface pletely uses synthesis mechanization mining the well farmland slant length is bigger, and incline the coal seam for the , and coal seam geology condition etc. factor effects, deciding this well farmland inside the plete adoption slant. Key word:Slowly inclines coal bed； Inclines the long wall to pick；Synthesis mechanization mining coal 3 目 錄 摘 要 .............................................................................................................................1 Abstract ........................................................................................................................2 目 錄 ...........................................................................................................................3 緒 論 .............................................................................................................................7 第 1 章 井田概況及礦井地質特征 ................................................................................8 井田概 況 .......................................................................................................8 礦區(qū)位置 ..............................................................................................8 地形地勢： ..........................................................................................8 氣象及地震情況 ...................................................................................8 水文地質情況 .......................................................................................9 煤田開發(fā)史 ..........................................................................................9 工農(nóng)業(yè)及原料供應狀況 ........................................................................9 水源及電源 ..........................................................................................9 地質特征 ....................................................................................................... 10 礦區(qū)內的地層情況 ............................................................................. 10 井田范圍內和附近的主要地質構造 .................................................... 11 煤層賦存情況及可采煤層特征 ........................................................... 12 巖石性質 厚度 特征 .......................................................................... 13 水文地質情況 ..................................................................................... 14 沼氣、煤塵及煤的自燃性 .................................................................. 14 煤質、牌號及用途 ............................................................................. 14 勘探程度及可靠性 ...................................................................................... 15 4 第 2 章 井田境界 儲量 服務年限 ........................................................................... 17 井田境界 ..................................................................................................... 17 井田周邊狀況 ..................................................................................... 17 井田境界確定的依據(jù) .......................................................................... 17 井田的未來發(fā)展情況 .......................................................................... 17 井田儲量 ..................................................................................................... 17 井田儲量的計算 ................................................................................. 17 保安煤柱 ............................................................................................ 18 儲量計算方法 ..................................................................................... 18 儲量計算的評價 ................................................................................. 19 礦井工作制度 生產(chǎn)能力 服務年限 ........................................................... 19 礦井工作制度 ........................................................................................ 19 礦井生產(chǎn)能力的確定 .......................................................................... 19 礦井服務年限 ..................................................................................... 20 第 3 章 井田開拓 ..................................................................................................... 21 概述 ............................................................................................................ 21 井田內外及附近生產(chǎn)礦井開拓方式概述 ............................................ 21 影響本設計礦井開拓方式的原因及其具體情況 ................................. 21 礦井開拓方案的選擇 .................................................................................. 21
