凤凰山铜矿充填采矿技术的应用与发展

Application and Development of Mining Technique with filling in Fenghuanshan Copper Mine

凤凰山铜矿自投产以来，采用了上向水平分层充填采矿法、大直径深孔嗣后充填采矿法和无间柱连续开采充填法。在多年的生产实践中，该矿的充填采矿技术得到了不断的发展和完善。作者针对矿山的实际，对现行采矿方案的改进提出了建议。

Overhand horizontal cut and fill stoping, large diameter long hole stoping with subsequent filling, and backfilling method with continuous stoping without stope pillar have been applied at Fenghuangshan Copper Mine since it went into operation. The mining technique with filling has been uninterruptedly developed and improved in production practice over many years at the mine. Author suggests improving current stoping scheme in view of the mine reality.
