Fixed-length roof cutting with vertical hydraulic fracture based on the stress shadow effect: A case study

Fixed-length roof cutting with vertical hydraulic fracture based on the stress shadow effect: A case study

Pre-driven longwall retracement roadway (PLRR) is commonly used in large mine shaft. The support crushing disasters occur frequently during the retracement, and roof management is necessary. Taking the 31107 panel as research background, the roof breaking structure of PLRR is analyzed. It is conclud...
