Mechanism of piper gas emissions from coal seams

  • Published:
Journal of Mining Science Aims and scope

Abstract

Effect of sudden squeezing of mined-out coal seam on piper gas emissions into a mine working is described. The boundary problem is formulated for gas filtration from squeezing zone into the worked-out space, and the results of numerical calculations are cited. The coal seam permeabilities that give rise to appearance of technogenic pipers are evaluated.
