ASSESSMENT OF STRESSES ON GAS CONTENT OF THE MARGINAL PART OF A COAL SEAM
Journal Title: Вестник научного центра по безопасности работ в угольной промышленности - Year 2016, Vol 1, Issue
Abstract
Description of the developed method and the coal seam gas kinetic characteristics measurement results received by gas pressure and temperature controlling in asks with drilled coal samples are presented. High convergence of results for parallel samples and their correspondence to the known geological gas content reduction at the marginal part of the seam effected by stresses reduction are received.
