METHOD FOR DEGASSING ROCK MASSIF

摘要

A method for degassing a rock massif includes penetration of degassing work, drilling degassing wells from it, tightening those and captation of methane. Degassing working is penetrated in worked-out unloaded from rock pressure massif in parallel to ventilation drift and at distance from it equal to distance to maximum of bearing pressure. The wells are drilled from degassing working in clusters with gaps equal to spacing of roof breaks to zones of the highest stratification of rocks of the rock massif.
