Abstract:

Ore bunker is the throat project of underground metal mine.During the process of transportation，the ore is lashing and abrasion each other，which is easy to cause collapse accident of ore bunker.The good running state of ore bunker has an important influence on sustained and stable development of mine enterprise.Taking the repair of ore bunker of a gold mine as an example，the failure mechanism of ore bunker and selection of treatment scheme are introduced in detail.By comparing the advantages and disadvantages of three treatment schemes，including pipe grouting method，layered casting method and newly-built ore bunker，the results show that pipe grouting method has the best treatment effect and shortest duration，finally pipe grouting method is adoped to treatment ore bunker，it has a certain reference for engineering treatment of similar mines.

Key words:  ore bunker treatment, pipe grouting method, repair project, collapse of ore bunker, metal mine
