- W2356765658 abstract "In order to test adaptability and directed blasting parameters of slotted cartridge in rock driving,firstly,design of blasting parameters is optimized,and making the hole utilization rate reach more than 90%,the requirements of rapid driving and smooth blasting are reached.Secondly,after the success of blasting program,the both-sides comparison experiment of the surrounding holes and all surrounding holes comparison experiment are made,hole mark rate can reach 90%.At the same space,the best charge is 0.5 kg,and it can be less 16.7% and 37.5% than smooth blasting and ordinary blasting.At the same charge,blast-hole space can be extended from 450 mm to 550 mm,improvement rate is more than 22%.The experiment results show that control blasting using the simple slotted cartridge can be better for forming and taking more benefits for enterprise;it is suitable for spread in rock rapid driving." @default.
