Investigation of Flexible Materials for Personnel Shield.
NTIS: PB/221-278 Available for Reference At Bureau Libraries :30 pages
Since roof falls in the vicinity of the working face in underground coal mines are a major source of fatalities and injuries in the nation's coal mines, it is evident that the present systems of temporary support for use in this working area are ineffective. This seems to be chiefly due to the inconvenience of setting up heavy and awkward devices such as jacks and posts, which also interfere with the movement of men and machines in this critical working area. This program was concerned with defining and testing commercially available materials that could be used as support elements in a more convenient flexible personnel shield. Five specific materials were tested. It was recommended that a heavy denier nylon fabric coated with a polyester resin be considered for use as a flexible personnel protective shield in coal mines.
