Study of Reasonable Roof Cutting Parameters of Dense-Drilling Roof Cutting and Pressure Relief Self-Forming Roadway in Non-Pillar Mining

Roof cutting by dense drilling is one of the main methods of gob-side entry retaining. Taking the 203 working face of the Ruineng Coal Mine as the engineering background, a mechanical model is established to clarify the roof breaking mechanism. Numerical simulation is conducted to analyze the roof c...
