摘要: 针对新集二矿2101采区连续开采存在采掘接替紧张的问题,在210102工作面应用预掘腰巷沿空掘巷,即待210106工作面回采超过腰巷后再施工210102机巷里段|在210100工作面采用预掘机巷沿空留巷,待210102工作面回采后再进行巷道修护。预掘巷道开采技术的应用,有效解决了采掘压茬期对连续开采的限制,实现了2101采区工作面的连续开采,对类似条件下区段内连续开采具有较好的借鉴价值。

Abstract: Aiming at the problem that the continuous mining of first coal layer of the Xinji second mine is in a tense situation, the limitation for continuous mining in superseding time can be settled effectively by employing the reserved narrow coal pillar and roadway excavation technology in 2101 mining zone, and at the same time realize the continuous mining of woking faces and obtain good social and economic effects.
