在地下矿采矿中，矿石大块的产出是不可避免的。大块不仅影响矿山生产，而且二次破碎费用高。以水为介质，成功研制了新型水炮碎石器。应用表明，其大块破碎效果理想，安全性好，基本上无飞石、炮烟等有害作用，且具有较好的经济效益，是一种低成本、高效率的新型大块破碎设备，具有推广应用价值。

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 bazardous fumes.
