研究岩石可钻性有两个目的:一是根据岩性合理地选用钻头和最优钻进规程;二是拟定机台的生产指标.只要通过研究工作对岩石的机械性质进行定性分类,即可满足前者的需要;而解决后一个问题,还需有定量的指标,并达到一定的准确程度.岩石可钻性的研究不仅要反映现阶段的设备水平,而且必须考虑施工的技术条件. The study of rock drillability has two purposes: one is to use the drill bit rationally and the optimal drilling procedure based on lithology, and the other is to develop the production index of the machine bench. As long as the rock mechanical properties are qualitatively classified through research work, To meet the needs of the former; and to solve the latter problem, there must be quantitative indicators, and to achieve a certain degree of accuracy. The study of rock drillability not only reflects the current level of equipment, but also must consider the construction of technical conditions.
