Abstract

The invention discloses a combined aerobic and anaerobic microorganism treatment system and method for gas in a mine goaf. The system comprises two parts: an aerobic methane-oxidizing bacteria agent spraying system and an anaerobic methane-oxidizing bacteria agent spraying system; the components comprise a methane-oxidizing bacteria agent storage tank, a pressure pump, a spraying pipe network, a nozzle and the like; the methane-oxidizing bacteria agent storage tank is connected with the input end of the pressure pump, and the output end of the pressure pump is connected with the spraying pipenetwork; the spraying pipe network is connected with the nozzle to form the spraying system. The method comprises the following steps: (1) culturing aerobic and anaerobic methane-oxidizing bacteria agents; (2) arranging the aerobic methane-oxidizing bacteria agent spraying pipe network system; (3) arranging the anaerobic methane-oxidizing bacteria agent spraying pipe network system; (4) regularlyspraying a methane-oxidizing bacteria agent and a culture solution; (5) testing effects. The danger of gas in the goaf can be reduced by regularly spraying the methane-oxidizing bacteria agent and theculture solution thereof into the goaf and removing methane by utilizing microbial metabolism.

Description

technical field [0001] The invention relates to a combined aerobic and anaerobic microbial treatment system and method for gas in a mine goaf, belonging to the technical field of coal mine gas treatment. Background technique [0002] With the rapid and sustainable development of my country's economy, the demand for coal is increasing. At present, shallow coal resources are nearly exhausted, and many coal mines have begun to enter deep mining. With the increase of mining depth, gas disasters are becoming more and more serious, and the difficulty of coal mine gas control is increasing. The goaf is formed by the caving of the roof strata after the mining of the working face. This area has a large scope and increases continuously with the mining of the working face. At the same time, the residual coal in the goaf is continuously oxidized due to the influence of air leakage and gas extraction, and there is a heat storage environment. After meeting the temperature conditions, sp...
