Experimental and measured research on three-dimensional deformation law of gas drainage borehole in coal seam
Using self-researched gas drainage borehole stability dynamic monitoring device, three-dimensional deformation characteristics of borehole under steady vertical load were researched experimentally and systematically. This research indicated that under the action of steady loading, the mechanical def...
