PECULIARITY OF COAL SEAM GAS PERMEABILITY INCREASE
Journal Title: Вестник научного центра по безопасности работ в угольной промышленности - Year 2016, Vol 1, Issue
Abstract
The problems of methane extracting from high gas content coal seams are reviewed. Some scienti c and technical peculiarities of coal seam permeability increase in order to improve gas pre- drainage ef ciency are demonstrated.
