title: [Prevention of methane emission by pre-tele-injection of water into the layer].
abstract: This paper describes trials of pre-tele-infusion carried out at Zolder mine, of the Kempense Steenkolenmijnen, as part of a research project on the control of methane emission. An increase in output of more than 25% (accompanied by a reduction in dust concentration) with no significant increase in total methane emission is reported. Furthermore, a reduction in total emission of between 13 and 22% was observed when an infused panel was worked above a coal seam which had also been infused.
