高深溜井井筒堵塞的爆破处理实践

溜井是采用平硐-溜井方式开拓矿山的运输咽喉,溜井正常与否对矿山生产影响极大。本文通过黑沟铁矿高深溜井井筒堵塞处理实例,对其堵塞爆破处理方法及经验做了系统分析。重点介绍的爆破冲击波破拱疏通高深溜井井筒高位堵塞的爆破方法,富有新意,可供国内外同类型矿山参考借鉴。

BLASTING TREATMENT PRACTICE OF DEEP DROP SHAFT WELLBORE PLUGGING

Drop shaft was used to exploit mines,which had a great impact on the mine production.Systematic analyses were made on its processing method and experiences combined with the case of deep drop shaft wellbore plugging process in the Heigou mine.The innovative blasting method which was introduced importantly to resolve wellbore plugging caused by the blasting shock wave was available for the type of mine as a reference at home and abroad.
