| Abstract: | In order to solve the problem of over-limit of CO in the goaf of 22109 working face,through the analysis of the mechanism of nitrogen injection technology in the goaf,combined with the specific geological conditions of the working face of 22019,the scheme of reducing the CO content in the goaf of the working face by the nitrogen injection scheme Carry out specific design.The results show that after the implementation of the nitrogen injection scheme,the concentration of CO in the goaf is reduced to less than 20ppm,which solves the problem of CO overrun and provides a guarantee for the safe production of the mine. |
