A technical approach based on microbial technology is proposed to help resolve the problems caused by explosive gasesin coal mines. The proposed technique uses methanotrophic bacteria to oxidize methane. In laboratory experiments, theoxidation eect of hanging nets impregnated with liquid containing methanotrophic bacteria was investigated at dierentair flow-rates. The experimental results showed that the volume of gas degraded and the gradient of degradation bothincreased as the gas concentration increased at constant air flow-rates. At fixed gas concentrations, the volume ofdegraded gas increased with increasing flow-rates of air at low flow-rates. However, the volume of degraded gas slightlydecreased with increasing flow-rates of air at high flow-rates. These experimental results provide a theoretical basis forthe treatment of explosive gases during exploration for natural gas and to treat potentially dangerous concentrations ofgas in gobs, caves and upper corners of mineshafts. They will also be of great practical significance in coal mining.
