Findings from Sichuan University Provide New Insights into Mining and Metallurgy (Failure Behavior and Energy Evolution Characteristics of Deep Roadway Sandstone Under Different Microwave Irradiation Modes)

摘要

2023 APR 12 (NewsRx) – By a News Reporter-Staff News Editor at Mining & Minerals Daily Daily – Research ffndings on Technology - Mining and Metallurgy are discussed in a new report. According to news reporting out of Chengdu, People’s Republic of China, by NewsRx editors, research stated, “Efffcient breaking of hard rock and prevention and control of rock burst disasters are two key concerns for construction in deep areas with high in-situ stresses and are two of the most important ways to ensure the safe and efffcient construction of deep engineering. Therefore, this study considers microwave weakening and fracturing of hard rock, taking the duration of a single microwave irradiation treatment as a variable, and synchronously combines mechanical testing and acoustic emission monitoring methods to demonstrate the possibility of rock burst disaster prevention and the control with this treatment method.”
