Tests of rock-dust barriers in experimental mines

Rice, G.S. / Greenwald, H.P. / Howarth, H.C.

Qualities of successful barrier; proper position, construction, and loading of barriers; index to grade severity of explosions in barrier testing; installation factors affecting success; effect of character of loading material and dispersion; barriers are secondary safety devices and must not be used as substitute for rock dusting. (see also Colliery Guardian v 145 n 3740 Sept 2 1932 p 433-5; and Iron and Coal Trades Rev v 125 n 3362 Aug 5 1932 p 193-4)
