It can adapt for 58years, and is divided into tw o levels. Average alignment in farmland in w ell lengthw ays 4500 ms, average slant lengthw ays 4300ms, average rake angle in coal seam 11176。 提升設備為主井采用箕斗提升，副井采用罐籠提升。 本設計礦井采用雙立井的開拓方式，集中大巷布置方式。服務年限為 61a。設計井田的可采儲量為 。屬于緩傾斜煤層。年工作日為 330 天， “ 四 、 六 ”式工作制，工作面長為 180m，每刀進度為，每 日割 9 刀。因此，本設計中難免會出現(xiàn)一些問題，請各位專家老師不吝指正。 The well farmland turns to is divided into totally 15 adopt the zone mines and 2 w orked faces. This worked fe ce is w est six w orked face, words 300 days every year. Adapt “theeeight” work situation, work face is 135 meters length of circle is , and times is 4 one day. Because the well farmland slant length is bigger, and incline the coal seam for the , a nd 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 Adoption slant I 目錄 摘 要 ....................................................................................................
