The　charge　structure　is　the　critical　to　determine　the　bench　blasting　effect　of　rock　slope.　Through　theoretical　calculation,　model　testing,　and　numerical　simulation,　a　formula　for　calculating　the　stress　attenuation　of　the　axial　hole　wall　of　the　segmented　charging　structure　is　proposed.　Moreover,　the　influence　mechanism　of　the　explosive　ratio　and　interval　packing　length　on　the　internal　damage　distribution　of　the　concrete　of　concrete　specimens　under　a　segmented　charging　structure　of　the　cuttings　is　described.　Finally,　the　research　results　are　applied　to　the　mining　of　a　rock　slope　in　southwest　China.　The　research　results　reveal　the　following:　1)　The　pressure　at　the　charge　section　is　highest　when　the　rock　debris　interval　charge　is　used,　and　with　the　increase　in　the　charge　section　distance,　the　pressure　markedly　decreases-sharply　first　before　stabilizing.　In　the　upper　filling　interval　charge　section,　the　minimum　pressure　corresponded　to　approximately　the　midway　point　of　the　filling　section,　and　the　stress　distribution　on　the　axial　hole　wall　is　concave:　high　at　both　ends　and　low　in　the　middle.　2)　The　ratio　of　the　upper　and　lower　sections　of　the　explosive　column　determines　the　form　of　blasting　damage,　and　the　range　of　blasting　damage　increases　first　and　then　decreases　with　the　increase　in　the　length　of　the　rock　debris　in　the　interval　section.　3)　The　field　test　shows　that　compared　with　the　traditional　blasting　charge　structure,　the　optimized　segmented　charge　structure　can　reduce　the　blasting　block　rate　by　13.1%.　4)　Using　the　optimized　charge　structure,　the　explosive　unit　consumption　can　be　decreased　from　0.27　kg/m(3)　to　0.24　kg/　m(3),　which　improves　the　economic　benefits　of　mining　and　construction　of　related　mines.
