Aiming at the problems of stress concentration at the end of 23107 working face, the top coal was difficult to be broken and affected the top coal release, with theoretical analysis, numerical simulation, field working test and digital panoramic borehole peeper technology, the blasting parameters were determined and optimized, and the field working test showed that the effect of cutting the top and relieving pressure was remarkable, and an obvious conductive fissure zone was formed after blasting, which provided a good reference for future research on related problems, which was a good reference for future research on related issues.
