Description
Technical field
Face sky old working compound closure wall and its method of construction the present invention relates to one kind.
Background technology
At present, during mine development end often need disclose closed face sky old working, because after exposure driving face with adopt
Dead zone directly connects, and needs chosen position immediately to be reclosed to facing sky old working, at this stage, more using filling slag bag or structure
Brick wall is built to play support and leakproof wind action, but because slag is more loose, situation about leaking out is still present, and constructing brick wall needs
When it is more long, goaf exposes for a long time, easily causes that toxic and harmful 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 to shake and is quickly conducted to construction tunnel along facing sky old working.Therefore the region becomes mine disaster
Keypoint treatment region, affect mine safety production.
The content of the invention
The technical problem to be solved in the present invention is the drawbacks described above for how overcoming prior art, there is provided one kind is faced sky old working and answered
Close enclosing wall and its method of construction.
In order to solve the above technical problems, originally facing sky old working compound closure wall, it is characterised in that：It is wooden including wooden pillar

Effective support and protection.
Single, the common sky old working enclosing wall that faces meets with one to secondary big ore deposit shake, connects at top or both sides usually occur
Crack, it has to repaired.And use and originally face sky old working compound closure wall, shaken after more than ten ore deposits, it is still as excellent as before.
It is so designed that, quick construction, can in time separates goaf, and by goaf to construction lane, set gradually painting
Rubberized canvas, high molecular foam material layer, coal ash bag wall layers and reinforced concrete wall, mechanical strength are increasing, on the one hand can be with
Reliable support is provided and is sealed, prevent the toxic gas in goaf excessive, the excavation collapse that on the other hand can successively decrease layer by layer draws
The ore deposit shake of hair, it is ensured that construction tunnel safety.
Used as optimization, the Grouting Pipe is made up of 4 inch steel pipes, the standby Guan Youyi bars.It is so designed that, simple structure,
It is convenient.
As optimization, the high molecular foam material layer is by foaming is rapid, in course of reaction the less Sai Fute of heat production or
Roc is stopped and is made.It is so designed that, foaming is rapid, spraying is convenient, the characteristics of unsuitable dry and cracked after compression, serves quick closure mined out
Area, prevent spontaneous combustion of coal seam and the excessive effect of toxic and harmful.
Used as optimization, the coal ash bag wall layers also iron wire rhombus net including both sides, the coal ash bag is just piled up in both sides
Iron wire rhombus net between.Be so designed that, easy construction, it is ensured that coal ash bag wall layers do not collapse less than.
As optimization, three layers of iron wire rhombus net, every layer of iron wire rhombus net surrounding point are provided with inside the reinforced concrete wall
Anchor pole is not provided with, and above-mentioned anchor pole is squeezed into the top board, base plate and both sides rib or the palisades that face sky old working respectively, every layer of iron wire
Rhombus net is separately fixed on the anchor pole head of anchor pole or anchor pole substrate.It is so designed that, iron wire rhombus net is fixed on periphery by anchor pole
Tunnel, with concreting together with, forms firm, consolidation enclosing wall, safe and reliable.
The foregoing method of construction for facing sky old working compound closure wall, comprises the steps：
1. cooks up one section of 5 meters of region long on sky old working is faced, face sky old working lane top below fix Grouting Pipe,
