Study on the influence of grouting pressure on seepage characteristics of drill hole sealing section
Gas drilling and extraction is one of the important means of gas control. In order to effectively improve the sealing effect of drilled holes, the influence of drilling grouting pressure on the sealing effect was studied. The permeability test and the scanning electron microscope (SEM) were carried...
