Experiments on multiple short-delay blasting of coal (in two parts)
Technical Report
·
OSTI ID:7320568
In 1949 a study was undertaken in Bureau of Mines Experimental coal mine near Pittsburgh, Pa., to investigate conditions under which simultaneous multiple and short-delay multiple blasting of coal may be used without danger of igniting gas or coal dust in coal mines and to study the vibrations of the mine roof during such blasting. Results of blasting and roof-vibration tests are given. Paper presented at Sixth International Conference of Directors of Safety in Mines Research at the laboratories of the Charbonnages de France, Verneuil (Oise) France, July 24-29, 1950.
