Abstract
A quick-reaction, mine-permissible rescue vehicle (merv) was developed for use by rescue teams. The merv, a six-wheeled, battery-powered unit with life support equipment and instrumentation, is designed for a two-person team with provisions for handling two victims or tools in a trailer. The merv, which is 100 inches long, 56 inches wide, and a maximum height of 34 inches, can be lowered down most mine shafts and has clearance to travel mine railways. The merv has power to all six wheels that can be transmitted separately to either or both sets of wheels. Low-pressure, high-traction tires give the vehicle the ability to handle soft, muddy mine floors, flooded areas and significant obstacles, and can negotiate a 45 degree grade. Power and life support are sufficient for a 4-hour mission. The life support system is a commercially available, approved unit currently used by MSHA rescue personnel. A payout wire system provided communication between the merv and home base over a distance of 10,000 feet. On-board monitoring of carbon monoxide, methane, and oxygen is provided, with master and individual alarms to warn of gas concentrations outside preset limits.
