It can adapt for 69 years, and is divided into one levels. Average alignment in farmland in w ell lengthw ays 4500 ms, average slant lengthways 2200 ms, average rake angle in coal seam 10176。, 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 17 adopt the zone mines and 1 w orked faces. This worked fece is east one w orked face, words 330 days every year. Adapt “foursix” w ork situation, w ork face is 160 meters length of circle is , and times is 9 one 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 redi fy 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 .........................................................................
