Abstract: |
During the mining of deep mines, rock bursts occur from time to time due to high ground stress and complex geological conditions. Using a variety of rockburst criteria, combined with AHP-FUZZY comprehensive evaluation of the rockburst tendency of deep rock masses, and combined with the actual situation of the mine, rock burst prevention measures were proposed, and two types of feasible support plan were designed based on the rock burst support design principles. , the stress concentration position, size and other parameters and failure characteristics were analyzed, the original plan of the mine was used to compare, and the support was optimized. It provides practical reference value for the prevention and control of rock burst in mining. |
