Abstract:
An atmospheric detection system for use in a mine, comprising: a continuous miner having a rotary cutter head attached to a frame and a motor for driving said rotary cutter head; a sensor adapted to sense an atmospheric condition mounted to said continuous miner and movable therewith; a first power line for supplying power to said motor; a controller coupled to said motor and said first power line for controlling rotation of said rotary cutter head at a remote location; a second power line for supplying power to said sensor; a display coupled to said sensor for displaying the sensed atmospheric condition at a location remote of said sensor; an exhaust fan provided on said continuous miner; an air flow sensor attached to said continuous miner for sensing an exhaust velocity of; an oxygen sensor attached to said miner; and a carbon monoxide sensor attached to said continuous miner, wherein said air flow sensor, said oxygen sensor and said carbon monoxide sensor are coupled to said display for displaying the atmospheric condition sensed at each of said sensor locations.
