―四、六 ‖式工作制，工作面長為 200m，每刀進度為 ，每日割 9 刀。屬于緩傾斜煤層。設計井田的可采儲量為 。服務年限為 60a。 本設計礦井采用雙立井的開拓方式，集中大巷布置。 提升設備為主井采用箕斗提升，副井采用罐籠提升。 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。 V 井底車場及硐室 .............
