Coal mine air tempering: effectiveness, design, and roof support. Report of Investigations/1985
Technical Report
·
OSTI ID:6274769
Shale-roof deterioration in coal mines, caused by ventilation air-humidity fluctuations, is a common ground-control problem. Shale-roof deterioration often results in increased accidents, decreased production, inadequate ventilation, and increasing operating costs in maintaining haulage roads and airways. The results of Bureau of Mines research indicate that air-tempering entries are an effective method of controlling deterioration-prone shales. Some of the conclusions and recommendations drawn from Bureau research include (1) moisture-sensitive shales will react adversely to moisture gains and losses.
