Abstract

Abstract: For the sake of solving the leakage problem relative to the ordinary bags used in extraction of methane from coal seams, increasing the volume fraction of methane in the mixture, and ensuring underground work safety, a new kind of split bag sealing device and a new sealing technology were developed, and a comparison of the effect was made between the split bags and the ordinary bags by carrying out an engineering test. The results show that for a given, coal seam, the volume fraction of the extraction methane in the mixture inside the boreholes sealed with the split bag grouting devices is 69.3% after 70 days, but that with the ordinary bags is only 31.4%, and sealing the hole with the split bag grouting device can effectively solve the serious problem of air leakage relative to the ordinary bag grouting devices.

Key words: methane extraction, grouting hole sealing, grilling leakage, bag hole sealing, split bag, extraction effects
