Statistical Investigation of the Mineralogical Effect on Blastability in Granitic Rocks

Deu Muhendislik Fakultesi Fen Ve Muhendislik
In this study, the effect of physico-mechanical and mineralogical properties of core samples taken from granite rocks obtained from different locations on blastability was statistically analyzed. The relationship between the mineral content of the rocks and rock mechanics parameters was evaluated. The best regression equations with strong relationships

A New Blastability Index for Hard Roof Management in Blasting Gallery Method

Geotechnical and Geological Engineering, 2012
The presence of hard and massive sandstone above the coal seam in underground coal mines often leads to delay in caving of overlying rock beds thereby causing excessive load on supports and posing danger to underground workings. The problem is more prominent in blasting gallery (BG) as well as longwall mining methods in Indian coal mines.

Prediction of the Blastability Designation of Rock Masses Using Fuzzy Sets

International Journal of Rock Mechanics and Minings Sciences, 2010
The main objective of rock blasting design is to achieve a balance among optimum powder factor, proper fragmentation, throws, ground vibration, etc. The in-situ rock mass properties are among the most important contributory factors in fragmentation.

Development of an Assessment System for the Blastability of Rock Masses

International Journal of Rock Mechanics and Minings Sciences, 1999
Intact rock properties and the discontinuity structure of a rock mass are among the most important variables influencing blasting results. This influence is considered to be a composite intrinsic property of a rock mass and is referred to as the blastability of a rock mass.

A neural network approach to comprehensive classification of rock stability, blastability and drillability

International Journal of Surface Mining, Reclamation and Environment, 1995
ABSTRACT Comprehensive classification of rock masses, an important activity during exploration, design and construction for underground openings, is restrained by our limitations in defining the complex geological environments and in modeling the relationships between geological features and rockmass behaviors. In this paper we present a novel approach
