摘要
伊敏露天矿正处于二采区向三采区扇形转向过渡期间的关键时期,对转向过程中的关键技术进行了系统性、前瞻性的分析与研究,提出通过改变转向方式、改变半连续采煤系统推进角度、调整采矿分层关系等措施,充分增加半连续采煤工艺系统有效工作线长度,形成合理可行的采区转向工程实施方案,保证半连续采煤工艺系统扇形转向期间年度生产能力。
The mine is in sector transition period from the second to the third mining area,the article analyzes and researches the key technology,presents some measures by changing the steering mode,changing the propulsion angle of the semi continuous coal mining system and adjusting the mining layering relationship.The mine fully increases the effective working line length of semicontinuous coal mining system,and forms a reasonable feasible mining area transition project implementation plan,and ensures the annual production capacity during semi continuous mining system sector transition.
