Experimental Study on Dissolution of Basaltic Rocks

2011-2-19  Dissolution rates of three basaltic rock samples from Japan (Fuji (sample1) and Hachijyojima (sample 2) fresh basaltic rocks, and Kitamatsuura (sample 3) altered basaltic rock) were experimentally determined in a pH range from 3 to 11 at 25°C. Initial dissolution rate constants are high (-9.9 ∼ -10.4 in logarithmic unit) .

Damage modeling of basaltic rock subjected to cyclic

Damage assessment of basaltic rock mass due to

2009-3-1  Blasting remains the most economic method of rock excavations, however, the losses associated with the blast induced damage is becoming cause of concern for safety and productivity among the mining and civil projects. Rock mass damage in underground openings occurs mainly due to blast induced forces, stress redistribution and weathering.

Textural identification of basaltic rock mass using

2009-9-9  A new approach to identify the texture based on image processing of thin sections of different basalt rock samples is proposed here. This methodology uses RGB or grayscale image of thin section of rock sample as an input and extracts 27 numerical parameters. A multilayer perceptron neural network takes as input these parameters and provides, as
