Recent rock-dusting experiments for arresting coal-mine explosions
Technical Report
·
OSTI ID:7220488
An investigation was made in Experimental coal mine at Bruceton, Pa., to determine efficacy and safety of dispersing rock dust by explosives and to ascertain whether explosive gas-air mixtures or coal dust might be ignited during such rock dusting. Some recent experiments on bag-type devices are described in which each unit was provided with a burster for scattering rock dust in path of explosion.
