采礦工程畢業設計論文-雞西礦業集團小恒山煤礦18mta新井設計(已修改)

　

【正文】 I 摘 要 本設計為雞西礦業集團小恒山煤礦 ，共有 4層設計可采煤層，分別為 3上、 3下、 18和 34。 煤層傾角 11176。，地質構造簡單。井田平均走向長 4400m，平均傾斜長 4500m， 煤層總厚度為 。 設計井田的工業儲量為 ，可采儲量為 。服務年限為 54a。 本設計礦井采用雙立井的開拓，劃分兩個水平開采。兩個水平均為上、下山后退式開采，采用帶區式準備，采煤工藝為綜合機械化采煤。礦井共劃分 8個帶區，其中達產帶區為 2 個，達產工作面 2 個。本設計帶區為西一帶區 ，大巷裝車式下部車場，大巷運輸采用兩臺 10t 架線式電機車牽引 3t 底卸式礦車。采用“四六”式工作制，年工作日為 330d，工作面長為 210m，每刀進度為，每日割九刀。 提升設備為主井采用箕斗提升，副井采用罐籠提升。每日凈提升時間為16h。 由于井田傾斜長度較大，且為緩傾斜煤層，以及煤層地質條件等因素影響，決定本井田內全部采用傾斜長壁采煤法開采。 由于本人能力有限，缺乏一定的現場經驗。因此，本設計中難免會出現一些問題，請各位專家老師不吝指正。 關鍵詞 可采儲量 采煤工藝 礦井設計 全套圖紙，加 153893706 II Abstract This design for the Jixi mining industry group small coal mine , altogether has 4 designsto be possible to pick the coal bed, respectively is on under 18 and 34. The coal bed inclination angle 11176。, the geologicstructure is simple. The well field equally moves towards long 4400m, medium bank long 4500m, coal bed total thickness is , belongs to the coal bed. The design well field mercial production , the recover ableresources is . The service life is 54a. This design mine pit uses the double vertical shaft the developmentway, delimits divides two levels mining. Two water averages for on,descend a mountainmining. Uses the belt area type preparation,backlash type mining, the mining coal craft for synthesismechanization mining coal. The mine pit altogether divides 8 beltsareas, in which reaches produces the belt area is 2, reaches producesworking surface 2. This design belt area for the west area area, thebig lane installs lower part the car type the cart yard, the big laransportation uses two row 10t electric lootive to tow the 3t mine car. The year working day is 330d, the use four, sixthe type work system, the work face length is 210m, each knifeprogress is , shears 9 knives every day The lift technique primarily well uses the promotion,the vice well uses the cage promotion. Only promotes the time is 16hevery day. Because the well field inclines the length to be bigger, also for the coal bed, as well as factor influence and so on coal bedgeology condition, decided in this well field pletely uses inclinesthe long wall to pick mining. Because myself ability is limited, lacks the certain , in this design unavoidably can have some problems, asksfellow experts teacher to point out mistakes.
