Mining Contract: Development of Guidelines for Safely Managing Electrical Equipment and Systems in Underground Mines During Mine Emergencies and Other Abnormal Circumstances

This page is archived for historical purposes and is no longer being maintained or updated.
Contract # 200-2008-26556
Start Date 8/13/2008
End Date 9/30/2009
Research Concept

This contract developed guidelines to enable workers and emergency response personnel to safely manage electrical equipment and systems in an underground coal mine during a mine emergency or under other abnormal circumstances. Guidelines are needed to address a lack of mining industry consensus regarding interpretation and implementation of 30 CFR requirements and best practices for shutting off electrical power in a mine emergency to avoid possible ignition of a hazardous atmosphere. The guidelines address other key issues such as: maintaining operation of critical mine monitoring and communication/tracking systems, coordinating with necessary mine evacuation and rescue operations, and compliance with current regulatory requirements, including new MINER Act provisions.
