采礦工程畢業設計論文-雞西哈達煤礦09mta新井設計[3](已修改)

　

【正文】 I 摘 要 本設計新井為雞西礦業集團哈達煤礦 ，共有 3 層設計可采煤層， 分別為 3 3 39煤層， 平均總厚度為 。設計井田的可采儲量為 。服務年限為 60a。劃分兩個水平開采。 井田 最大 走向長 5100m，平均傾斜長 3600m，煤層平均傾角 9176。，屬于緩傾斜煤層。 本設計礦井采用雙立井的開拓方式，集中大巷布置。共劃分 6 個帶區，其中首帶區為 1 個，達產工作面 1 個。本設計帶區為 中一 ，大巷裝車式下部車場，綜合機械化采煤。年工作日為 330 天，采用 ―四、六 ‖式工作制，工作面長為 200m，每刀進度為 ，每日割 9 刀。 提升設備為主井采用箕斗提升，副井采用罐籠提升。 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。 由于本人知識有限，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 傾斜開采 全套圖紙，加 153893706 II Abstract The task of this design is to construct a tons new shaft for jixi Ming mine has three minable Coal Seam,and its average thickness is field of minable capacity is million tons. It can adapt for 60years, and is divided into two levels. Average alignment in farmland in well lengthways , average slant lengthways , average rake angle in coal seam 9176。, belong to the the slant the coal seam. This mine shaft is applied to double indined shaft development method。 Layout of gathing gallergand mining district eross heading。 The well farmland turns to is divided into totally 6adopt the zone mines and 1worked faces. This worked fece is west six worked face, words 330 days every year. Adapt ―foursix‖ work situation, work face is 200meters length of circle is , and times is 9one day. Because 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. Because my limit working ability and time. There must be lots of faults in this design. I plead with dirextors point them out and redify it, and I will accept it sincerely and humblely. Key words Recoverable reserves The technology of coal mining III Adoption slant 目 錄 摘 要 .......................................................................................................................
