Abstract
The invention discloses microbiological control technique used to control and reduce coal mine gas content. It includes the following steps: inoculating the filtered high efficiency oxidized fungus mixed culture to a living filter; controlling air flow velocity and nutrient feeding to make the living filter reach the maximum of the methane removing efficiency. The invention can oxidize the methane aggregated in the coal mine channel into carbon dioxide and water which can reduce the methane density by 70%-95% compared with the original methane content.
Description
Technical field
The present invention relates to coal mine production safety, be specially a kind of microbial degradation technology of utilizing, reduce coal mine gas concentration, prevent the technology and the method for methane accumulation.
Background technology
Gas is the gaseous material in fossil energy (coal, the oil etc.) forming process, and its main component is methane (CH
4), in air, reach certain concentration, meet naked light fierce blast will take place.Gas explosion must possess 3 conditions simultaneously: the one, and burning things which may cause a fire disaster; The 2nd, oxygen (oxygen content is more than 12%); The 3rd, the concentration of gas itself is in 5%～15% scope.When gas density is lower than 5%, in no case gas explosion can take place; When gas density in the air surpassed 15%, gas is no longer blast also, and just burning (under the situation of oxygen abundance); In order to prevent gas explosion, the major measure that people take now will avoid 3 conditions of gas explosion to set up simultaneously.During mine is produced, conventional way, the one, prevent methane accumulation, not allowing the digging space gas density to occur transfinites, and promptly the gas density in digging space is well below the minimum of gas explosion; The 2nd, prevent that gas from being ignited, burning things which may cause a fire disaster can not appear in the digging space.The 3rd, prevent the expansion of gas explosion accident.Essential measure is two of fronts.This invention is to adopt biodegradable method to prevent gas gathering in the colliery.This technology is based under the condition of aerobic, and biting methane backeria is the principle of carbon dioxide with methane oxidation.
Methane-oxidizing bacteria is to be sole carbon source and energy aerobic bacteria with methane, can be used for controlling and reduces gas bearing capacity in the colliery, reaches the purpose of safety in production to a certain extent.
Summary of the invention
The object of the present invention is to provide the control of microorganisms technology of methane concentration in a kind of control and the minimizing tunnel, colliery.
Technical scheme of the present invention is:
A kind of control of microorganisms technology that reduces methane concentration in the coal mine atmosphere utilizes the method for methane-oxidizing bacteria degraded methane in the biofilter to remove methane.
The microorganism fungus kind of adopting is the mixed culture of the high-efficiency methane oxidation bacterium that screens from high concentration methane environment.Add the methane concentration that is used for reducing coal mine atmosphere in the biofilter to, can reduce gas bearing capacity 70～95%.
Advantage of the present invention and beneficial effect are:
1, utilization of the present invention is the oxidation removal methane of methane-oxidizing bacteria, and methane-oxidizing bacteria can adopt modern biotechnology to enlarge cultivation in a large number.
2, biofilter of the present invention is simple to operate, removes the efficient height.
3, to generate product be water and carbon dioxide in the present invention, need not handle again, both reduced the danger of gas explosion, reduced the discharging of methane as greenhouse gases again.
Description of drawings
Fig. 1 is apparatus of the present invention structural representation.
The specific embodiment
In methane concentration was lower than 10% Minepit environment, this device can reduce 70-95% with the methane concentration in the air inlet by induction air flow ratio control, by reciprocation cycle, reached and reduced methane concentration in the air, prevents the purpose that methane gathers.
Biofilter is that the glass of dosing bio-carrier is leant on formation, and methane-oxidizing bacteria is that prior cultured methane-oxidizing bacteria is dosed up, and the biomass maximum can reach 50 gram (weight in wet base)/L.
The air inlet methane concentration can by regulating flow velocity, guarantee the time of staying at 2 minutes-1 hour between 1%-10%, the methane of 70%-95% can be removed.

2, by the described method of claim 1, it is characterized in that: the gas under the aerobic conditions in the coal mine atmosphere fully contacts with methane-oxidizing bacteria when flowing through biofilter, and wherein most of methane are oxidized to fall to become water and carbon dioxide.
3, by claim 1 or 2 described methods, it is characterized in that: a large amount of methane-oxidizing bacterias of inoculation in biofilter.
4, by the described method of claim 2, it is characterized in that: be added with microbe carrier in the biofilter, they can be organic and inorganic matters, can be natural or artificial sinteticses.
