The principles of rock blasting dynamics and related engineering applications in the recent years are reviewed. The main issues are covered in blasting cave range, various determination methods for failure zones, theories of short-wave and weak-wave in near-field of cave blasting, the movement in plastic regions and mechanical parameters in far-field, and rock fracture under blasting for underground works. The laws of blasting effects in uniform media in indoor test are also introduced, which include heterogeneous and homogeneous characteristics of geostress, fissure, and shllow-buried cave in laboratory simulation or experimental test. The actual rock blasting tests are touched in failure effects of near-field, seismic effects in far-field, and irreversible deformation regions. The latest similarity research results in underground blasting, shallow-buried blasting (throwing and directional blastings) are also presented. In addition, engineering applications of rock blasting dynamics in various fields are briefly introduced. Filnally, some ideas and prospects are proposed for later research in rock blasting dynamics.
