Occurrence, research and combating sudden outbursts of coal and gas in Canada: M38-8/28E-PDF

"In Canada sudden outbursts have occurred only in coal mines. Because outbursts of potash and gas do occur in other countries, and because we are currently opening several new potash mines, we have an interest in their mode of occurrence in saline rocks. However, all of our experiences and studies regarding outbursts have been concerned with those of coal and gas. […] our studies have shown the influence of stress, coal strength and deformation, gas content, and permeability on outburst occurrences. At present the only effective control measure that is applicable in Canadian conditions is shock blasting, and the application of mechanization in outburst-prone seams is restricted by our inability to predict or eliminate these curious and hazardous phenomena"--p. 1, 18.
