镶齿滚刀的破岩机理及分形研究

Fragmentation Principle and Grading Research of Tungstem-carbide-tipped Cutter

反井钻机在水电行业的施工应用中,遇到了岩石坚硬,施工进度较慢的问题,通过对镶齿滚刀破碎花岗岩粒的分形研究,找出镶齿滚刀破碎花岗岩的规律,为滚刀的设计开发提供理论指导。

During applying raise boring machine in construction of hydropower industry, it met the problem of excessive solid rock which slows down the construction. In facing this problem, shows a grading research of fragmentation of gragnit by tungsten - carbide - tipped curer, and find out the rule of fragmentation of gragnit by tungsten - carbide - tipped cutter, and then provide the academic instruct for the design of cutters.
