摘要
探讨了天安煤矿504首采区的布置及装备,得出结论:天安煤矿504首采区走向长400 m,宽460 m,单翼开采。设计开采储量3761kt,服务年限3.1a。回采工作面循环产量353.9 t,工作面生产能力89.3万t,采区生产能力98.2万t/a,能满足矿井产量要求。
The layout and equipments of the No.504 initial mining area in Tian＇an mine is discussed in the paper. The results show that the No.504 initial mining area is 400 meters in length and 460 meters in width and one-way mining should be used. The design reserves is 3 761 kilotons, service life 3.1 year, cycle production 353.9 tons, and production capacity of working face 893 000 tons and mining area 982 000 tons, which could meet the production requirement.
