Description
Technical field
It the utility model is related to one kind and face sky old working compound closure wall.
Background technology
At present, during mine development end often need disclose closed face sky old working, because after exposure driving face with adopting
Dead zone directly connects, and chosen position need to be reclosed immediately to facing sky old working, at this stage, more using filling clinker bag or structure
Brick wall is built to play support and leakproof wind action, but because clinker is more loose, situation about leaking out still has, and constructing brick wall needs
When it is longer, goaf exposes for a long time, easily causes that toxic and harmful gas is excessive and the spontaneous fire in goaf, and wall is pressurized easy
, there is erecting dense individual props or explosion time in deformation, and shock resistance effect is undesirable, if excavation collapse triggers ore deposit shake, existing enclosing wall is very
Crack just occurs soon, causes ore deposit shake quickly to be conducted to construction tunnel along facing sky old working.Therefore the region becomes mine disaster
Keypoint treatment region, affect mine safety production.
