Investigation on Pressure Relief and Roadway Protection Technology by Subsection Hydraulic Fracturing under Strong Mining Pressure in Fully Mechanized Mining
In this study, we analyzed the deformation and stress changes of an auxiliary transport gateway in Buertai coal mine 42106, which is a fully mechanized coal face. We used the directional long drilling hydraulic fracturing technology to weaken the mine hard roof clearance and investigated the overall...
