Description

technical field [0001] The invention belongs to the technical field of explosion simulation, and in particular relates to a large-equivalent underground multi-point delay explosion crater effect simulation device and method. Background technique [0002] With the successful application of various blasting technologies in transportation, construction of water conservancy and hydropower projects, exploration and development of energy and mineral resources, and disaster prevention and mitigation of geological disasters, the scale of engineering blasting has continued to expand. At present, many projects adopt multi-point blasting schemes. The preparation of such complex charge configuration schemes is mostly based on empirical formulas of geometric similarity. However, a large number of blasting practices have shown that when increasing the scale of underground explosions, gravity must be considered when throwing craters. The role in the process, the development of a simulation...
