Abstract
The invention discloses a methane treatment technique through microbe in coal mine, which main comprises, injecting methane-oxidizing bacteria, spray methane-oxidizing bacteria to roadway space, chamber, coal face, heading face, goaf and blocking room of mine, or preparing methane-oxidizing bacteria by device to oxidize and degrade firedamp on aforementioned place.
Description
Technical field
The present invention relates to safety of coal mines and field of environment protection, particularly a kind of in the technology of administering coal mine gas and reducing discharging methane in atmosphere.
Background technology
Coal is the main energy sources of China, accounts for about 70% of the disposable energy of China at present, and along with China's rapid economy development, coal seems more important day by day as the energy status of China.At present, the coal mine gas disaster is seriously restricting coal in China production, and the technology of administering coal mine gas at present mainly relies on physical means such as mine ventilation, gas drainage under suction.But, because continuous increase along with the China's coal-mine mining depth, seam gas content increases thereupon, and improving constantly along with the mechanization degree of coal mining, coal mining intensity continues to increase, so the gas relative amount of mine gas emission in colliery and the absolute outburst amount of gas also constantly increase, and be accompanied by the mash gas dynamic phenomenon, even coal takes place give prominence to gas.Therefore, be difficult to get rid of and dilute the gas that pours in the digging space, reach the gas density requirement of " safety regulations in coal mine " by mine ventilation; Drawing out methane in advance from the coal seam is the another important technical of control coal mine gas, but, China's condition of coal seam occurrence more complicated, the gas permeability in most coal seam is poor, cause the coal bed gas drainage difficulty, the extraction rate is lower, the gas major part in coal seam still can be along with mining work is discharged into the digging space, because the limitation of the gas of colliery control at present technology, cause the China's coal-mine gas accident frequently to take place, caused great casualties and economic loss, so, it is imperative to research and develop new improvement technology for coal mine gas, and microbiological degradation technology for coal mine gas is filled up the biotechnology of administering coal mine gas just.
In addition, the greenhouse effects that gas causes atmosphere are 20 times of carbon dioxide, are 7 times of carbon dioxide to the destruction of ozone layer, and China's coal-mine ranks first in the world to about 100 billion cubic meters of airborne release gas every year, accounts for 1/3rd of global drawing-off gas total amount.Utilize the microbial degradation coal mine gas can significantly reduce the gas amount of colliery, help improving greenhouse effects to airborne release.
Summary of the invention
In view of this, the present invention proposes and a kind ofly utilize microorganism in control coal mine gas disaster with reduce the technology of colliery to airborne release methane (main component of coal mine gas is a methane).Its principal character of the present invention is to utilize the characteristic of methane-oxidizing bacteria degraded methane, the gas in the oxidative degradation colliery.
According to above-mentioned purpose, the present invention proposes and a kind ofly utilize microorganism in control coal mine gas disaster with reduce the technology of colliery to airborne release methane (main component of coal mine gas is a methane), comprise following content:
1, in the coal seam under the coal mine, utilizes methane-oxidizing bacteria oxidative degradation gas in lane space, chamber, coal-face, driving face, goaf and the enclosure space.
2, in the coal seam, inject methane-oxidizing bacteria oxidative degradation coal-bed gas by the hole of drilling.
3, spraying methane-oxidizing bacteria or by the degrade gas in these places of the device of preparation methane-oxidizing bacteria oxidative degradation gas in the lane space under coal mine, chamber, coal-face, driving face, goaf and the enclosure space.
The specific embodiment
1, before the back production of coal seam, according to situations such as coal-bed gas geological condition, gas bearing state, gas bearing capacity, gas pressures, parameters such as the pattern of design injection methane-oxidizing bacteria boring, pitch of holes, hole depth, aperture, calculate the bacterium amount of injection methane-oxidizing bacteria and the composition and the quantity of nutrient solution, inject the bacterium liquid that contains methane-oxidizing bacteria by boring then, speed and efficient according to methane-oxidizing bacteria oxidation gas, after reaching the degraded index, can begin back production is carried out in the coal seam of degraded.
2, for the gas in the lane space under coal mine, chamber, coal-face, driving face, goaf and the enclosure space, space size, ventilation situation, gas emission and parameters such as lack of uniformity of gushing out and gas density according to these places, quantity and the occupation mode of methane-oxidizing bacteria used in design, by direct spraying methane-oxidizing bacteria or by the degrade gas in these places of the device of preparation methane-oxidizing bacteria oxidative degradation gas.
Claims (4)
1, a kind ofly utilize microorganism in control coal mine gas disaster with reduce the technology of colliery to airborne release methane (main component of coal mine gas is a methane).Its principal character is to utilize the characteristic of methane-oxidizing bacteria degraded methane, the gas in the oxidative degradation colliery.
2, technology according to claim 1 is characterized in that: utilize methane-oxidizing bacteria oxidative degradation gas in the coal seam under the coal mine, in lane space, chamber, coal-face, driving face, goaf and the enclosure space.
3, technology according to claim 2 is injected methane-oxidizing bacteria oxidative degradation coal-bed gas by the hole of drilling in the coal seam.
