Explosion hazards in gassy and non-gassy oil shale mines
As a part of its continuing research on the safety aspects of oil shale mining, the Bureau of Mines has adapted its tube-bundling sampling techniques, previously applied to coal-mine fires, to the monitoring of methane in a deep oil shale mine. The sampling techniques can be used to increase saftey during mining as well as to permit better prediction of gas to be found in future mining. Correlations are shown between the methane observed from the outgassing of core samples and the methane encountered in mining. Although background levels are low, considerable methane was observed following blasting. Tests in the Bureau's Experimental Mine demonstrated oil shale dust explosions in the absence of methane as well as the effect of small amounts of methane on the lower explosion limits of oil shale dust. Recent research on ignition or dust layers is reported. 20 refs.
