Abstract
The invention provides an industrial culture system and method for methane-oxidizing bacteria used for a coal mine. The industrial culture system comprises a feeding system, a gas circulation system, a gas pressure conversion system, a monitoring system and a heat preservation system which are separately connected with a closed microorganism culture system. A culture site adopted in the invention is an coal-mining industrial plaza; the microorganism culture system can be linked with a ground grouting system of the coal mine to realize culture-application integration; a methane-oxidizing bacteria culture process is simple, a methane gas source is convenient to obtain, the utilization efficiency of bacteria liquid is high, and culture time is not limited; the industrial application situations of application to a mine upon culture in the mine and culture at any time for application at any time can be realized, the technical problem that large-area culture in a laboratory is limited by factors such as activity, economy and safety of the methane-oxidizing bacteria is solved, and abundant bacteria sources can be provided for research, development and production of derivative products; and the method has the advantages of degrading methane by the methane-oxidizing bacteria, realizing synergistic outburst elimination of a coal seam and preventing and treating gas overrun, and providing a basic guarantee for large-area production of methane-oxidizing bacterium derivative products.
Description
technical field [0001] The invention relates to the field of coal mine gas disaster prevention and control, in particular to an industrial cultivation system and cultivation method for methane oxidizing bacteria used in coal mines. Background technique [0002] Coal and gas outbursts and gas explosions are still one of the major disasters threatening the safety of gas mines. At present, the main mode of gas disaster prevention and control technology is pressure relief protection layer mining-drainage drilling or pressure relief protection layer mining-enhanced hydraulic fracturing, hydraulic slotting, coal seam water injection, loose blasting, gas fracturing, etc. Drainage Borehole Drainage. In the actual production process of coal mines, there are still frequent phenomena of gas exceeding the limit, and coal and gas outburst accidents also occur from time to time. Therefore, it is of great value and significance to study new prevention and control technology models to effe...
