Open publisher page 0 citations

Abstract

Oversized boulders are unavoidable in underground mining operations, which not only affect normal mining production, but also lead to high secondary fragmentation cost. An innovative water blasting-based rock breaker has been successfully developed for this purpose in which water is used as a medium. Field application indicates that it is a low cost and highly efficient new breaking device for over-sized boulders, which achieves good fragmentation with excellent safety performance , causing no flying rocks or hazardous fumes.
