A panel discussion of new MSHA diesel engine regulations is planned for the 1998 Fall ASME ICE Division conference to be held September 26-30 in Peek’n Peak Resort in Clymer, NY.

Proposed new federal (MSHA) and state level (PA, WV, VA, OH) mining regulations address diesel particulate matter (DPM) exposure. Because DPM and coal dust are mostly made up from the same material (Carbon), ambient PM measurements in coal mines are difficult at least. However, laboratory test results from an 8-mode cycle combined with the known ventilation air can be used to calculate ambient exposure levels for DPM.

To meet the proposed MSHA regulations, DPM must be reduced by 95% from existing engine-out levels. MSHA regulations also require that the entire engine system meet explosion-proof performance standards to operate in certain parts of the coal mine. This panel will explore the issues and challenges of the proposed DPM regulations and review the currently available solutions.

PANEL: Controlling Diesel Engine PM in Underground Mines

Moderator: Steve Fritz, SwRI

Part 1: The Issues

Michael Peelish - Cyprus Mineral Company

Labor:

CONCERN ABOUT WORKERS EXPOSURE TO DPM, Joe Main - United Mine Workers of America

Part 2: Solutions

Engines:
