微钻法进行岩石可钻性分级

Classification of the Drillability of Stone by Means of Micro-drilling

本文在分析现有典型岩石可钻性分级方法不足之处的基础上 ,提出了选择微钻法来研究金刚石钻进岩石可钻性的观点 ,阐述了微钻法需要解决的问题 ,同时确定选择综合参数W值来衡量岩石可钻性 ,通过室内微钻实验验证这种方法的可行性。

Based on the analyse on the shortages of typical classification methods of drillability of stone, this paper puts forward the micro-drilling method to research the drillability of stone by using diamond bit, and expounds the problems that need to be solved when we use micro-drilling method, at the same time we decide to choose the value of whole parameter W to scale drilling natures of stone, then by micro-drilling tests we confirm that the method is feasible.
