Abstract
An electrically powered methane sampling system for application on mining machines was designed, fabricated, and laboratory tested. The system will sequentially draw sample air at a controlled rate from up to three machine positions across the mine face and deliver the air to either an approved methane monitor, methanometer, or flame safety lamp. The prime considerations in the design were to provide an intrinsically safe water- and dust-resistant control box and an explosion-proof power box capable of being operated from the various mining power sources. The power box contains an internal battery that provides operating power prior to mining machine startup and after machine shutdown. The internal battery is recharged automatically when mining machine power is available.
