Experimental study on hole collapse characterization of gas drainage holes in this coal seam based on fiber bragg grating
Drill hole gas extraction is an important method to solve the problem of gas overrun. However, the mine gas extraction drilling hole is prone to collapse and deformation due to the influence of ground stress and drilling disturbance, which seriously affects the effect of gas treatment. Aiming at the...
