Abstract

Abstract

In this work we performed experimental tests using the dynamic strain test and high speed photography system to study the mechanism of the air-deck slotted charging structure blasting, with four axial air-deck structures adopted. The results show that the highest strain ratio reached 2.1 as the axial decoupling coefficient 1.5, and the corresponding function time of pressure was 9 μs. The best result of directional fracture was achieved. The crack propagation process was recorded by high-speed photography, which show that the propagation speed of the crack was not a constant. The expansion speed of the crack fluctuated with time, and illustrated the phenomenon. Finally, the field tests were performed in the underground tunneling and open slope projects with 1.50 and 1.66 as the axial decoupling coefficient respectively, and with good results achieved.
