Grouting and plugging technology of in-seam borehole methane drainage
Based on the analysis of the gas leakage mechanism and the principle of plugging in the surrounding rock of the in-seam borehole, a new grouting and plugging technology by separating the space and staggering time to cut off the air leakage channel was proposed. The separating space was embodied in...
