分矿房矿柱分层充填法在海底开采中的应用

Application of Room and Pillar Mining Method in Under-sea Deposit

三山岛新立矿区属于海底矿床开采,开采的关键是开采过程中海底不产生非均匀沉降、裂缝和塌陷。在安全开采的前提下实现强化开采,使生产能力达到8000t/d,必须选择合适的采矿方法。根据新立矿区开采技术条件,研究确定对厚大矿体采用分矿房矿柱分层充填法开采。

Xinli mining area of Sanshandao gold mine belongs to submarine deposit. The key point is without the inho- mogeneous sedimentation, crack and subsidence in exploitation of the seabed. Under safety mining and to strengthen the mining condition of making the productivity up to 8 000 t/d, the suitable mining method should be selected. According to mining condition in Xinli mining area, the room and pillar filling method for large and thick ore-body is determined after research.
