双鸭山矿业集团岭东煤矿0.9Mta新井设计（6#、14#、15#）（含全套CAD图）.doc

需全套CAD或三维图 联系QQ 695132052 摘要 本次设计新井为双鸭山矿业集团岭东煤矿0.9Mt/a的新井设计，共有3层设计可采煤层，平均总厚度为5.93m。设计岭东井田的可采储量为92.511Mt,服务年限为58.74a,划分两个水平开采。井田平均走向长2500m，平均倾斜长2000m，煤层平均倾角12°，属于缓倾斜煤层。 岭东煤矿采用双立井的开拓方式，分组集中大巷布置方式。共划分八个采区，其中首采区为1个，达产工作面1个。首采区为北一采区，大巷装车式下部车场，综合机械化采煤。年工作日为330天，采用“三·八”式工作制，工作面长为190m，每刀截深为0.8m，每日割七刀。主井采用箕斗提升，副井采用罐笼提升。由于岭东井田倾斜长度较长，且为缓倾斜煤层，以及煤层地质条件等因素影响，决定井田内全部采用走向长壁开采。 关键词 可采储量 采煤工艺 走向长壁 Abstract The mine designing that the new mine is Shuang Ya Shan City mining industry Corp. Ling Dong coal mine new of 0.9 Mt/a time designs capital, common 3 layer of the m designing that average general thickness is 5.93 tier may cut coal. Mt designing that Ling Dong mine-field workable reserves is 92.511, the length of service is 58.74 as, level dividing two exploit. The average trend of mine-field grows 2500 ms , average incline is long 2000 ms, average dip angle of coal seam 12, belongs to the slow incline coal seam. The developing way , grouping that the Ling Dong coal mine adopt to shaft pair concentrate big alleys arranging way. Divide eight mining area together, head mining area among them is 1 , amounts to 1 product face. Mining area is the north one mining area, the car park , synthetical mechanization cut coal on big alley entrucking style lower part. The annual workday is 330 day , adopt the three , eight dyadic character of service, face often is 190 ms , every knife intercepts depths being that 0.8 m, is everyday cut seven knives. The main shaft adopt skip lifting to fight against , the auxiliary shaft adopt a cage to be advanced. The length is longer since Ling Dong mine-field tilts, and for slow incline coal seam, inner affecting , deciding mine-field as mine as coal seam geology condition waits for a factor all adopt long trend wall coal mining law exploit.
