摘要
本设计为鸡西矿业(集团)。
此矿区内有三层可采煤层,,,,煤层平均倾角为20°。,可采年限为64a。本设计采用双立井开拓,划分18个采区,一水平可回采北一一、北一二、北一三,北二一、北二二、北二三、北三一、北三二、北三三采区,采用集中大巷布置,单一走向长壁采煤法,综合机械化回采工艺。本新井设计采用“四、六”式工作制,工作面长为190m,每刀进度为1m,每日割7刀。提升设备为主井采用箕斗提升,副井采用罐笼提升。通风方式为中央边界式通风。
关键词:开拓,水平,走向长臂
Abstract
This design is the new pit design of the Mt/ a to Jixi mineral industry group of Zhangxin mineral.
This mining area has totally three layers can adopt the coal seam , the average
thickness is metre, Strike length is km and inclined length is km average rake angle in coal seam 20°, designing the mine can adopt to keep the Mts of deal, the service time limit is 64 design adopts the pit two levels expand, dividing the line eight adopt the zone, a the level can return to adopt the north one one, north one two, south one three, north two one,north two two,north two three,north three one , north three one,north three two,north three three, the adoption concentrates the big lane arranges, one alignment lengthways the pit adopts the method of coal adopts the coal, synthesizing the mechanization return to adopt the craft . Adapt “four-six” work situation, work face is 190 meters, length of circle is 1 meters, and times are 7 one day. Main shaft adopts ship to hoist, auxiliary adopts cage to hoist. Ventilating the way is a central margin type to ventilate.
key words: expands , the level, alignment long wall
