Hydraulic flushing in soft coal sublayer: Gas extraction enhancement mechanism and field application
Abstract In China, one or several ultrathin soft coal sublayers are widely developed in the coal seam. Therefore, a method of using hydraulic flushing in soft sublayer to enhance the gas extraction in these particular coal seams is developed in this work. We first established a new fully coupled gas...
