Numerical simulation analysis and parameter optimization of pulsed laser rock breaking

Physica Scripta
Abstract Pulsed laser rock-breaking, as a novel and efficient rock fragmentation technology, contributes to enhancing the development efficiency of ultra-hard and ultra-deep oil and gas resources. However, current research on parameter optimization analysis for laser rock-breaking remains limited. Therefore, the parameter optimization
