摘要
充填接顶和采场脱水是应用充填采矿法的矿山急需解决的两个技术问题。结合某矿分段空场嗣后一次充填采矿法的多年实践,分析了充填接顶和采场脱水问题的产生原因,详细叙述了控制空场嗣后一次充填质量的改进技术。改进后,采场充填接顶率显著提高,充填采场基本无多余积水。改进技术对条件相似的矿山推广空场嗣后一次充填采矿法具有借鉴价值。
Roof-contacted filling and dehydration in stope are two critical problems in mines in which backfill mining method was used. Combining with several years experience on open stope backfill in one time, the causes of the problems were analyzed and some technique improvements were put forward. And then, the roof-contacted rate of filling was obviously enhanced; there was little seeper any more. It provides a good reference for similar mines.
