ABSTRACT:
A roof support for coal-mining apparatus or other tunnel-excavating equipment has a shield plate with several rearwardly diverging and deepening longitudinal grooves in its upper surface. The grooves are designed to carry off detritus as the support advances and are spaced closely enough to form ribs therebetween adapted to crush larger chunks of overburden landing thereon.
