Development of a Fluorescent Cap Lamp System.
NTIS: PB/249-906 Available for Reference At Bureau Libraries :62 pages
Prior to the date of this contract, ocean energy had developed and demonstrated a high-efficiency fluorescent cap lamp that operated from a standard 4-volt miner's cap lamp battery. This unit produced about five times the light output of the standard incandescent miner's cap lamp. A part of the effort under this contract involved the engineering, drafting, and technician support to modify the lamp in minor respects to satisfy the Mining Enforcement and Safety Administration and the Pennsylvania Bureau of Deep Mine Safety to enable the use of the lamp in underground coal mines where methane gas could be present. Additional effort was applied to interface with existing battery charging apparatus already present at most mine sites. An adapter cord was developed for electrical connecting using "pigtail" leads to the existing charger circuitry apparatus already at most mine sites. This adapter cable represented an economical method for using the cap lamp at large mines without substantial added investments in charging equipment by the mine operator.
