Effects of gas pressure on bursting liability of coal under uniaxial conditions
Journal of Natural Gas Science and Engineering, 2017 Abstract When exploiting deep high-gas coal seams with a bursting liability, complicated rockburst disaster conditions exist because of the combined influence of stress and gas pressure. An understanding of the influence of gas on the bursting liability of coal can enable an analysis of the mechanism of the rockburst induced by gas pressure and the ...

Experimental study on bursting liability index of coal considering creep pre-damage
Geotechnical and Geological Engineering, 2021In order to explore the influence of creep pre-damage on bursting liability of coal and rock, the creep pre-damage treatment of coal with different stress levels (0%, 30%, 45%, and 60%) was carried out, and the bursting liability index test was carried out. The variation rules of uniaxial compressive strength, impact energy index, elastic energy index,

Bursting liability indices of coal
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1981Abstract Natural coal's ability to store and release rapidly elastic strain energy seems to be a fundamental condition for the occurrence of rock-bursts in deep underground coal mines. In Upper Silesia where a number of existing mines work below a critical depth, several indices have been proposed and their numerical values found by experiment in ...

Evaluation of burst liability in kimberlite using support vector machine
Acta Geophysica, 2018Due to the complex mechanisms of rockburst, there is no current effective method to reliably predict these events. A statistical learning method, support vector machine (SVM), is employed in this paper for kimberlite burst prediction. Four indicators $$\sigma_{\theta } ,\sigma_{c}
