Research Summary

This project conducted research needed to make recommendations and guide policy or program decisions regarding the safety of batteries used in underground coal mines.
The research objectives for this project were addressed by way of the following project tasks:
to conduct experimental research of lithium battery ignition of flammable methane-air mixtures with the aim of demonstrating the potential ignition hazard of lithium batteries considered intrinsically safe, and then to identify potentially safer lithium chemistry alternatives based on comparative experimental evidence;
to gather information from large-format lead acid battery manufacturers, refurbishment service providers, and equipment users with the aim of developing recommendations for enhancing battery assembly construction, charging cable protection, and providing ignition safe disconnects; and
to develop guidelines to improve battery safety for underground coal mine communications and tracking system equipment, focusing on battery selection, integration, use, and maintenance.
