摘    要：本文在国内外各种单因素岩石分级方法的基础上,首次提出了一个多因素岩石分级的新方法。此法以现场测试为主,根据岩石多个物理力学性质指标的数据,在电子计算机上进行统计分析与计算,得出钻速预报方程和最后分级结果。其中,成功地运用了模糊数学和图形法对多因素指标进行综合评价。文章最后还讨论了一个勘探矿区分级实例的结果。

Abstract: A new method of multifactor classification for rock has been proposed in this paper for the first time on the basis of various methods of single factor classification for rock given at home and abroad. This method ad- vocates field testing. Then both the statistical analysis and calculation are carried out in computer according to the test figures of the indexes of several physicomechanic parameters. A predicting equation of drilling rate and the last results of classification would be obtained. Moreover, the concept of fuzzy sets and constellation graphical method are successfully applied to the multifactor comprehensive evaluation. Finally an example in an exploration mine field is discussed.
