Abstract

Knowledge of drillability of rock masses in engineering projects is very important in determining drilling costs In drilling operations so many parameters such as the properties of rock and the drilling equipment affect the drilling performance In this study after discussing the rock mass drillability process and identifying all the effective parameters interaction matrixes based on the rock engineering systems that analyze the interrelationship between the parameters affecting rock engineering activities is introduced to study the rock mass drillability tribosystem Given that interaction matrix codes are not unique numbers and then possible interactive intensities are calculated for each matrix and a group decisionmaking method Fuzzy–Delphi–AHP technique has been used to obtain appropriate weights As a result rock mass drillability index RMDI is presented to classify the rock mass drillability The results indicate the ability of this method to analyze rock mass drillability procedure Drilling data along with laboratory rock properties from Sungun copper mine were collected and were ranked according to the new classification system Fifteen zones at the mine site were ranked based upon the new index RMDI and a reasonable correlation was obtained between measured drilling rate at the zones and RMDI data
