| Resumen |
Methane-oxidising bacteria (species unspecified) grown on a large scale for feed supplements were suspended in mine water containing approprite nutrients. The suspension was sprayed on piles of coal in workings. In the case of one seam, spraying a 25m-long pile once a day for 23 days reduced methane output from the collected coal from 8.75 to 6.61m3/t and reduced ambient methane concentrations from 0.9-1% to 0.66%, which enabled an increase in coal output from 768t/day to 922t/day. For the 9 test sites as a whole, methane output from the mined coal was reduced by 40-60%. |
