Description
Technical field
The present invention relates to a kind of coal mine gob filling system and its placement method more particularly to a kind of control goaf bottoms
The pocket type filling system and its placement method of plate gushing water.
Background technology
China's coal-mine " under three "（Under building, under railway, under water body）Press coal commonplace.According to statistics, state-owned emphasis coal
Mine presses about 13,800,000,000 t of coal total amount, wherein building to push nearly 9,000,000,000 t of coal.It is practical to press coal amount with the continuous expansion of town size
Far above this number.Moreover, this part reserves is distributed mainly on, industrial foundation is preferable, exploit condition is advantageous, produces and needs
Ask eastern region particularly thorny, that economy is more flourishing, such as Shandong, Henan, Hebei, Anhui, Jiangsu province.By taking Shandong as an example：
Shandong coal has the production history of upper a century, and the whole province village, building are dense in addition, there is 1949, pressure coal village, coal under villages
Amount accounts for the 60% of recoverable reserves.According to Shandong Prov. Coal Industry Bureau's chief's Qiao Naichen introductions, if do not taken protective mining measure, remain
Remaining coal recoverable reserves is difficult to maintain 20 years, therefore, how to liberate pressure coal " under three ", extends old coal mining enterprise's mine service-life
As the important topic of influence Chinese energy safety and social stability.
Gangue is the waste generated in coal production and washing process, and coal production is equivalent to per annual emissions
10%~15%.Gangue total burden in the whole nation forms hillock more than 1700 up to 4,500,000,000 t at present, takes up an area ha more than 30,000, and
Just increased with the speed of annual 100000000 t.Gangue is stored up for a long time, occupies a large amount of soils, polluted source, and H is generated after spontaneous combustion2S、
SO2Equal pernicious gases constitute significant damage to ecological environment.How to realize that safe, the reasonable disposition of gangue becomes and is related to me
The critical issue that state builds a resource-conserving and environment-friendly society.In this regard, have the concept that scholar proposes " waste filling ",
Not only the safe disposal of gangue had been realized, but also has liberated " under three " and has pressed coal.
Waste filling is that the primary spoil in underground or earth's surface hillock spoil are transported to underground goaf, is adopted with waste filling
Dead zone reaches control movement, slows down the purpose of surface subsidence.Existing waste filling system is broadly divided into three kinds：
（1）" throwing cash ", is that spoil is delivered to goaf by rubber conveyer or drag conveyor, and there are fillings to owe to connect top amount
Greatly, pack completeness is low, and Gangue voidage is big, and decrement is big, controls movement, slows down lacking for surface subsidence effect difference
Point；（2）" throwing cash+tamping " is that the ramming mechanism pair of comprehensive mining hydraulic bracket rear placement is utilized after spoil is delivered to goaf
Spoil further consolidates, and compared with " throwing cash " mode, pack completeness increases, and Gangue voidage reduces, but there are still
It owes to connect top amount, and system need to install more ramming mechanism, system complex, the degree of automation are low；（3）" turning over bag filling " is
Packed spoil is thrown to goaf by bag overturning machine structure after spoil is packed, there are spoil bag accumulation it is unordered, each other exist compared with
Big gap, voidage is big, controls movement and slows down the poor disadvantage of surface subsidence effect.
Invention content
For the problem present on, the present invention propose it is a kind of control gob floor gushing water pocket type filling system and
Its placement method, the filling system and its placement method can realize the downhole crushed of primary spoil, spoil not gug, reduce and promoted
