Description:
A systems evaluation was undertaken to demonstrate the ability of miners wearing life support systems to operate conventional mining equipment and to mine coal at a test section in an active ventilated mine. Their ability to operate mining equipment and to perform other in-mine tasks was successfully demonstrated. No major difficulties were encountered in performing these tasks and the miners reported they had never been that comfortable before when working in a mine. The life support system provided cool, clean air for the miner and did not hamper his ability to work. The system was adequate to demonstrate the miner's ability to mine coal while wearing a life support system. However, mechanical failures in the chiller and rebreather module were experienced. Additional work to develop a totally reliable life support system and further testing under ventilated conditions are required before testing in an oxygen-free atmosphere. This volume contains the Appendices only. The titles are the following: Training manual; Operating and maintenance manual - MSA; Operating and maintenance manual - Cambion dehumidifier air exchanger; Operating and maintenance manual - emergency rebreather; Specifications - miner's life support system.
