| description | The utility model discloses a controlled blasting device for improving a stable angle of a stepped deep hole blasting slope of a surface mine. The device consists of a semi-cylindrical pipe body, two round rings and a sleeve, wherein the two ends of the semi-cylindrical pipe body are hooped by the round rings with equivalent diameters; the sleeve of which the diameter and length are equivalent to those of the semi-cylindrical pipe body is sleeved on the semi-cylindrical pipe body; water of which the volume is one third or half of that of the sleeve is filled in the sleeve; and the sleeve is sealed. The controlled blasting device for improving the stable angle of the stepped deep hole blasting slope of the surface mine has the advantages that by using the technical scheme, the damage of great detonation impact generated in the explosive blasting process to a reserved stepped surface can be effectively reduced; and a precisely-controlled stepped blasting fracture surface can be obtained, and explosion cracks ar |
