摘要
为了提高回采率,缓解衔接压力,基于跨山回采的基本理论,对东欢坨矿2182上工作面进行了跨山开采,对相关巷道进行了回撤、替回、充填、加固等工作,对关键性问题进行了深入的研究,取得了显著的经济效益,积累了宝贵的开采经验,对跨山回采技术的发展提供了依据。
In order to improve the mining rate and reduce link pressure,based on the theory of the crossing mountain mining,2182上mining face of Donghuantuo Mine was crossing mountain. Retracement,return,filling,reinforcement for related roadway were done,key issues were studied,achieving remarkable economic benefit,accumulating valuable experience,providing basis for development of mountain crossing mining technology.
