Influence of Deformation and Instability of Borehole on Gas Extraction in Deep Mining Soft Coal Seam
To study the effects of the three deformation instability modes of gas drainage borehole on gas drainage, the deformation instability mechanism of soft coal seams is analyzed, three deformation instability modes are proposed for soft coal seams, namely, complete holes, collapse holes, and plug holes...
