T/GRM 057.1-2023 Non-coal rock rockburst tendency evaluation specification Part 1: Indoor index determination and grade classification
Abstract
Scope: This document specifies the terms and definitions involved in the evaluation of the rock burst susceptibility of non-coal rocks, indoor indicators and grade classification, instrumentation and equipment, rock sample specifications, determination of the peak strain energy storage index, determination of the post-peak stress drop rate index, determination of the residual elastic strain energy index, and determination of the brittleness index. This document is applicable to the determination of indoor indicators and grade classification of rock burst susceptibility of rocks that can be processed into standard rock samples in non-coal underground mines and other non-coal underground projects. Main technical contents: 1. Indoor indicators and grade classification; 2. Instrumentation and equipment; 3. Rock sample specifications; 4. Determination of the peak strain energy storage index; 5. Determination of the post-peak stress drop rate index; 6. Determination of the residual elastic strain energy index; 7. Determination of the brittleness index
