## 8 Conclusions  
(1) The roof breaking on the side of the gob-side roadway was analyzed and the mechanism of pressure relief by deep-hole blasting was shown. The analysis proved that after blasting, the layer around a blasting hole is greatly dislocated, the stress balance of the initial state of the roof is destroyed and the stress zone concentration is redirected deep to a rock mass, away from the fractured rock mass. Meantime, the roof along the gob-side roadway can collapse along the cutting roof line what reduces the range of the hanging roof, reduces the additional load and displacement of the roadway. (2) The UDEC results demonstrated that after blasting, the peak stress in the coal seam decreased by 3.54 MPa, dropping from 39.23 to 35 MPa and a peak stress is transferred 6 m to the depth of a coal body. At the same time, the deformation of the roadway along the gob-side roadway after blasting is reduced, which aids in preserving the stability of roadway. (3) The experiment results illustrate that the height of the final cavity zone on the side of the cut roof was 3.3 times that observed on the side of the uncut roof, while the height of the fractured zone was 0.65 times higher. The movement of the overburden strata showed obvious regional characteristics. (4) By severing the rock connection between the roof and the working face, the stress from the overburden rock layers in the goat is unable to be directly transmitted to the coal seam. As a result, the pressure on the side where the roof was cut is lower compared to the side where the roof remains intact. (5) The results of a field test show that after the implementation of blasting along the gob-side roadway, the amount of drilling powder weight, micro-seismic events number and daily energy are decreasing, reducing the potential of a rock burst. Furthermore, the monitoring results from coal stress and mine pressure also illustrate that the blasting can reduce the pressure of the overburden strata and the generation of cracks within the coal seam, achieving a better effect on pressure relief. **Author Contributions:** Conceptualization, X.Z. and Z.M. ; methodology, X.Z. ; software, C.J. and J.Z. ; validation, C.J., J.Z. and J.C.; formal analysis, H.W. ; investigation, Y.C. ; resources, C.M. ; data curation, J.C.; writing--original draft preparation, C.J. ; writing--review and editing, X.Z. ; visualization, Z.M. ; supervision, X.Z. ; project administration, X.Z. ; funding acquisition, X.Z.
