【 摘 要 】

The article gives the theoretical and experimental substantiation for application of in-situ leaching combined with divided blasting of ore blocks. Blasting also involves injection of hot steams of chemical solutions with active oxidizers in rocks. The authors discuss the designs of explosive charges with inserted shells of chemical agents in them for the divided blasting and injection as well as the compositions of agents for in-situ leaching of gold, silver, molybdenum and copper leaching from ore pillars and deep-level rebellious ore.
