In order to prevent spontaneous combustion in the goaf of 10105 working face, by analyzing the principle of grouting (glue) fire prevention technology, according to the specific conditions of the goaf and the characteristics of the grouting (glue) construction process, determine the grouting (glue) fire prevention plan the position of the final hole of the drilling hole, the spreading radius of the grout, the distance between the holes, the arrangement of the holes, the grouting (glue) material and the grouting (glue) sequence and other parameters, and monitoring operations during the grouting (glue) process. The results show that after the grouting (glue) project is implemented, the CO concentration in the goaf is greatly reduced, and the CO concentration is reduced to a reasonable range.
