Description
Technical field
This utility model relates to a kind of coal mine gob filling system, particularly relates to a kind of pocket type filling system controlling gob floor gushing water.
Background technology
China's coal-mine " three times " (under building, under railway, under water body) pressure coal is commonplace.According to statistics, State owned coal mine pressure coal total amount about 13,800,000,000 t, wherein presses nearly 9,000,000,000 t of coal under building.Along with the continuous expansion of town size, actual pressure coal amount is far above this numeral.And, these part reserves are distributed mainly on that industrial foundation is preferable, exploit condition is advantageous, produce and the eastern region that demand contradictory is prominent, economy is more flourishing, such as provinces such as Shandong, Henan, Hebei, Anhui, Jiangsu.As a example by Shandong: Shandong coal has a production history of upper a century, the whole province village, building are dense in addition, have 1949, coal village of pressure, and coal under villages amount accounts for the 60% of recoverable reserves.According to Shandong Prov. Coal Industry Bureau's chief's Qiao Naichen introduction; if do not taked protective mining measure, residue coal recoverable reserves is difficult to maintain 20 years, therefore; how to liberate " three times " pressure coal, extend old coal mining enterprise and become the important topic affecting Chinese energy safety and social stability mine service-life.
Gangue is the garbage produced in coal production and washing process, and every annual emissions is equivalent to the 10%～15% of coal production.The whole nation total burden of gangue has reached 4,500,000,000 t at present, forms hillock more than 1700, takes up an area ha more than 30,000, and just with the speed increment of annual 100000000 t.Gangue is stored up for a long time, takies a large amount of soil, generates H after polluted source, and spontaneous combustion2S、SO2Etc. harmful gas, ecological environment is constituted significant damage.The disposal safe, reasonable how realizing gangue becomes the key issue that relation China builds a resource-conserving and environment-friendly society.To this, there is scholar to propose the concept of " waste filling ", both achieved the safe disposal of gangue, liberated again " three times " pressure coal.
Waste filling is that primary for down-hole spoil or earth's surface hillock spoil are transported to underground goaf, with filling goaf by gangue, reaches to control movement, slows down the purpose of surface subsidence.Existing waste filling system is broadly divided into three kinds: (1) " throwing cash ", it is, by rubber conveyer or drag conveyor, spoil is delivered to goaf, there is filling to owe to connect top amount greatly, pack completeness is low, Gangue voidage is big, decrement is big, controls movement, the shortcoming slowing down surface subsidence weak effect；(2) " cash+tamping is thrown ", it is the ramming mechanism utilizing comprehensive mining hydraulic bracket rear to dispose after spoil is delivered to goaf tamping further to spoil, it is compared with " throwing cash " mode, its pack completeness increases, Gangue voidage reduces, but still suffering from owing to connect top amount, and system need to install more ramming mechanism, system complex, automaticity are low；(3) " turning over a bag filling ", it is to be thrown packed spoil to goaf by bag overturning machine structure after spoil pack, there is spoil bag and piles up unordered, each other the bigger space of existence, and voidage is big, controls movement and slows down the shortcoming that surface subsidence effect is poor.
