Abstract

Abstract

In order to study the throw characteristics of rock debris after explosion, with a view of solving complicated problems involved in the two-phase gas-solid flow in a penetration channel, we propose a simulation scheme combining the use of FLUENT and EDEM softwares. Based on this scheme, we analyzed the medium debris's blasting process for different depth-diameter ratios and studied the factors that bear on the debris's transporting characteristics. The results show that debris transporting capability is directly proportional to the peak value of the explosion load, and is inversely proportional to the ratio of the channel depth to the channel diameter and the debris particle size.
