Abstract: This paper inspected the application effect of the deep-hole pre-splitting blasting technology in Zhaogu No.1 Coal
Mine, and verified that the technology reduced the initial pressure strength in the mining under the thin bedrock, avoided the
large area pressure of the working face, guaranteed the equipment of the working face from damage and personal safety, and
improved the working efficiency.

Key words: deep-hole pre-split blasting; initial pressure; overhang area
