Abstract: The heterogeneity in rock is a fact and is often ignored during blast design. It is crucial to know the part played by the microscopic as well as macroscopic geological elements of a rock mass in producing and controlling blast damage. The discontinuities create an imbalance in the dissemination of explosive energy causing poor fragmentation and blast damage. The rocks are aggregates of minerals and the textural arrangement of the minerals defines the strength of that particular rock. There is a significant scarcity of literature for the microscopic nature of rock and its behavior after interaction with explosives. The goal of this research work is to answer fundamental questions on the mechanisms of rock breakage by explosive loading at the microscopic level. The objective of the research work is to classify the microscopic structures influencing rock fracturing patterns; relating the explosive source geometry to damage and breakage, and determining the local physical parameters that correlate best with fracture and fragmentation using textural analysis and scanning electron microscope (SEM) analysis. The rock fracture mechanism is characterized using SEM analysis of the pre and post-blast rock samples. The paper deals with the texture properties and strength of rock material and their relation with respect to induced stress condition due to blasting. [ABSTRACT FROM AUTHOR]
