The large area overhanging of thick and hard roof is one of the critical reasons for inducing coal burst. Because of the shortcomings of deep borehole blasting and conventional hydraulic fracturing for the overhanging roof, the axial roof cutting tec

The stress environments of gob-side roadways (GSRs) are becoming increasingly complex during deep coal mining under thick and hard roofs. This leads to strong strata behaviors, including roadway floor heave, roof subsidence, and even coal bursts. Amo
