Based on Hongyuan Mine was high gas and coal and gas outburst mine, with low permeability coal seam, the difficult gas extraction, the low extraction efficiency, short of fuel concentration level, raising the quality of hole sealing to adopt new equipment, new technology, new methods, to improve hole sealing technology and the quality of the extraction from drilling hole sealing, single-hole pumping quantity and concentration of the gas extraction as a whole were adopted, which laid good foundation for ensuring safe and efficient production of the mine.
