经对金山煤矿井田开拓方案的可行性分析,得出:井田采用斜井开拓,仅设一个主水平开采全井田(水平标高+980 m),共分5个采区(801、1201、1301、1302、1303采区);1302采区为单翼采区,其余均为双翼采区;首采801采区,在8号煤层布置一个综采工作面,以保证设计生产能力的结论。

Feasibility analysis on the coal field development in Jinshan Mine concludes that the inclined shaft development should be adopted. Only one main level mining for the whole mine (elevation:+980m) is set. It is divided into 5 mining areas: No.801, No.1201, No.1301, No.1302, and No.1303. Among them, No.1302 is one-wing mining area, the others are double-wing. No.801 is mined first. A fully-mechanized mining face is placed on No.8 coal seam, which could guarantee the designed productivity.
