Abstract
A sheltering apparatus for use in the long wall face of mine wherein a plurality of plates are arranged in overlapping manner between a self-advancing support and an adjacent plate, and hung from wires whose ends are fixed to the supports through springs, and an air curtain is fixed at the front open portion of the support, whereby floating dust and falling dusty materials can be repelled from entering the inner space of the supports.
Claims12
A sheltering apparatus for use in the long-wall face of mine wherein a plurality of plates are arranged in overlapped manner between a self-advancing support and its adjacent one, and hung from wires whose ends are fixed to the supports, said plurality of plates forming an inner space between said self-advancing supports whereby floating dust and falling dusty materials can be repelled from the inner space of the supports.
In a mining apparatus of the type having a self-advancing support and at least one additional support spaced therefrom, at least one support wire between said self-advancing support and the adjacent additional support, a plurality of horseshoe-shaped overlapping plates suspended between said supports on said at least one support wire and substantially bridging the space between said supports whereby the entry of dust and dusty material into the space within said plates is substantially prevented.
