A New Approach to Represent Impact of Discontinuity Spacing and Rock Mass Description on the Median Fragment Size of Blasted Rocks Using Image Analysis of Rock Mass

Ali Azizi et al.

Summary: Various in-situ rock mass properties and blasthole parameters play a crucial role in rock fragmentation, with the blastability index being a key factor. The median discontinuity spacing and JPS rating exhibit complex variations in practice, requiring different analytical approaches for different blasting conditions.

Upscaling of fractured rock mass properties - An example comparing Discrete Fracture Network (DFN) modeling and empirical relations based on engineering rock mass classifications

D. Gottron et al.

Summary: This study compares Discrete Fracture Network (DFN) modeling with empirical relationships based on conventional engineering rock mass classifications to determine the elastic properties of fractured rock masses. The results show that incorporating intact rock properties in addition to classification scores in empirical equations yields more reliable estimates for predicting fractured rock mass properties.

A new approach to improve the assessment of rock mass discontinuity spacing using image analysis technique

Hassan Moomivand et al.

Summary: The study demonstrates that the mean discontinuity spacing varies with scanline direction, and a linear correlation exists between the grand mean measured discontinuity spacing and block size of artificial models. By applying image analysis to in-situ rock masses, a reliable solution to specify the mean value of discontinuity spacing is provided.

The Specific Length of an Underground Tunnel and the Effects of Rock Block Characteristics on the Inflow Rate

Alireza Shahbazi et al.

Summary: This study introduced the specific length of a tunnel and a new analytical model for calculating the block surface area of the rock mass. Analyzing the correlation between inflow rate to the tunnel and rock block characteristics, the research found that the tunnel length should at least be equal to the least common multiple of apparent spacings of joint sets, and developed a new model for calculating block surface area.
