Description
Technical field
It the utility model is related to goaf harnessing technology, more particularly to a kind of goaf casing pipe protection system.
Background technology
Goaf be by artificially excavate or natural geological movement below earth's surface caused by " cavity ", the presence in goaf
So that the safety in production in mine faces very big safety problem, personnel and plant equipment may all be hindered because goaf caves in
Evil or damage.Because Goaf Area has, latent property is strong, regular poor, the goaf top plate caving collapse feelings of spatial distribution characteristic
Condition is difficult to the features such as prediction, therefore, how to the distribution of Goaf Area, spatial shape feature and the inbreak shape in goaf
Condition etc. carries out quantization judge, is always that puzzlement engineers and technicians carry out goaf potential hazard evaluation and rationally determined mined out
Punish the key technology difficulty of countermeasure in area.
At present, underground vacant areas has become an important problem for restricting mine development, as mine is to deep mining,
Ground pressure increase, underground vacant areas is depressed on powerful ground, cave-in accident easily occurs, especially turns opencut shadow to underground
Sound is very big；The substantial amounts of stope of underground mining residual, chamber, tunnel do not carry out timely processing, strip mining transformation are brought serious
Hidden danger, while carry out serious threat to mine staff and equipment belt.Lost after particularly most of Medium and smaller mines exploitations
A large amount of undressed goafs have been stayed, have caused mining worsening condition, the potential safety hazard thus brought is more and more prominent.
When being administered to the goaf formed after mining, the method that mainly uses at present include filling treatment method,
Avalanche facture, ore pillar and artificial post supporting methods and closing method.Filling treatment method establishes filling system, is reached by obturation
To the purpose of bashing, but this method needs complicated filling system, while needs to expend substantial amounts of human and material resources and wealth
Power, management are also more complicated；Avalanche processing rule limited by factors, as earth's surface whether allow avalanche, earth's surface whether
The construction of structures of protection in need or other facilities etc.；Ore pillar and artificial post support rule need to be constructed inside goaf
Operation, engineering time length, it is difficult that artificial post connects top；Closing rule must closed periphery slotting to see hard bottom firmly side with ore-rock again
Real walling is connect, slotting can only use sledgehammer, hammer drill, pickaxe or mechanical execution, and forbidding must be smooth using method of blowing out, metope, and
The shirt rim no less than 0.2m is wiped with, brick wall should wipe one's face, polishing compacting, and work stone wall answers jointing, and construction requirement is strict, process time length
It is and cumbersome.
Because above method has certain drawback, domestic Medium and smaller mines will not use substantially, common practice be exactly
In tunnel set up a warning sign come inform front it is dangerous, or directly abandon regardless of, hidden danger existing for goaf is not played
Any protective action.
Utility model content
The purpose of this utility model be to provide it is a kind of it is economical and practical, simple to operate, applied widely, can effectively reduce and adopt
Collapse the goaf casing pipe protection system of brought geological disaster for dead zone.
This goaf casing pipe protection system provided by the utility model, including it is arranged on each tunnel connected with goaf
Interior divider wall and pile up the barren rock cushion on gob floor, the barren rock cushion extend in each tunnel with every
Inner side from wall connects completely.
The divider wall includes bar-mat reinforcement, some anchor poles and concrete guard wall, concrete guard wall closure with goaf
Connection each tunnel in, bar-mat reinforcement is embedded in each end face of concrete guard wall, each anchor pole be closely coupled to concrete guard wall with
Between the wall in tunnel.
The draining square hole being communicated with the bottom of the divider wall inside and outside divider wall.
It is communicated with the bottom of the divider wall on the outside of divider wall and the water drain casing tube in goaf.
Trend of the anchor pole along tunnel is at least disposed with two rows, often arranges radial direction of the anchor pole along tunnel wall and is at least disposed with
Ten.
The divider wall is apart from least 10 meters of the outward flange in goaf.
The thickness that the barren rock cushion is located on gob floor is at least 1 meter.
The thickness of the divider wall is 2 meters.
The utility model when carrying out goaf harnessing after applying to mining excavation or exploitation, can directly using artificial or
Scraper piles up barren rock on gob floor, forms one of substantially flat barren rock cushion, can be filled barren rock
Point utilize, decrease or even eliminate goaf and collapse the harm brought；Divider wall is recycled to enter the tunnel for connecting goaf afterwards
Row closure, goaf can be reduced and collapsed the impact wave harm brought, effectively alleviate the power that country rock big inbreak in goaf triggers
Disaster is impacted, mining security can be effectively improved, play the purpose in comprehensive regulation goaf.The utility model has economy
The advantages of practical, simple to operate, applied widely, the improvement in goaf after be particularly suitable for use in mining excavation or exploitation.
