【正文】 I 摘 要 本設計礦井為雞西礦業(yè)集團東山礦 。地質構造為單斜構造，共有可采煤層為 4 層，分別為 3上、 3下、 6A 和 6B 煤層總厚度為 。設計井田的工業(yè)儲量為 ,可采儲量為 Mt，礦井的設計服務年限為 57a。煤層傾角為 10176。屬緩傾斜煤層，本礦井設計采用雙立井開拓方式，劃分為三個水平， 3 個采區(qū)， 2 個工作面達產，采用采區(qū)式準備方式，達產時采區(qū)個數(shù)為兩個。大巷運輸采用 14t 架線式電機車牽引 3t 底卸式礦車運輸，區(qū)段運輸平巷采用帶式輸送機， 輔助運輸為 固 定式礦車，工作面采用刮板運輸機。采煤方法為走向長壁倒退式采煤法，采煤工藝為普通機械化采煤工藝。工作面的支護方式采用單體液壓支柱和鉸接頂梁聯(lián)合支護，頂板處理方法為全部跨落法。 提升設備為主井采用箕斗提升，副井采用罐籠提升。工作面年工作日為 330d，采用 “三、八 ”工作制，工作面長為 160m，循環(huán)進度為 ，每日進刀次數(shù)為 5 刀。通風方式是分區(qū)抽出式。 由于本 人水平有限 ，工作能力及現(xiàn)場經驗 不足 ，故本設計中出現(xiàn)一些問題在所難免，請各位專家老師不吝 賜教 。 關鍵詞 ：礦井設計 。 走向長壁采煤法 。 全部跨落 全套圖紙，加 153893706 II Abstract The design of the mine in Jixi Mining Group Dongshan Mine Mt / a new mine design. Geological structure of the monoclinic structure, the total coal seam to four layers, namely, 3up、 3down、 6 A and6 B the total thickness of the seam . Mine design of industrial reserves of Mt, recoverable reserves of Mt. Mine design service life for a 57a. Seam inclination of 10 176。 is a gently inclined coal, the mineshaft design using pioneering approach is divided into three levels. 3 Mining District, two face up to the middle, using readymining area, production of mining area when the number to two. Roadway transport the 14 tlinear motor vehicle traction 3 tbottom tub transport, Section transport roadways used belt conveyor, auxiliary transport of t fixed tub, face scraper used transport aircraft. Mining method for regression toward longwall mining, mining technology to ordinary mechanized mining technique. Face support method used hydraulic prop and Articulated joint support the roof all the way to handle crossloading method. Well mainly to upgrade equipment used winder, using cage belonging to upgrade. Face to 330 days, 3, 8 system, Face to 160 m long, the progress of cycle m, the number of daily feed of the five knives. Ventilation is the wayout area. Given the limited, and the ability to work and field experience, so the design inevitable that some problems may occur, asked the experts to teachers not hesitate to assume. III Keywords : mine design。 Longwall mining method。 Alltrans IV 目 錄 摘 要 .......................................................... I ABSTRACT ........................................................
