Abstract
The invention provides a method for evaluating deep-buried tunnel blasting parameters, and belongs to the technical field of mine engineering. The method comprises: setting multiple diverse blasting schemes; selecting a plurality of test sections with the same geological characteristics, the number of the test sections corresponding to the number of the blasting schemes; blasting the test sections using the blasting schemes, and obtaining diversified monitoring data of each test section; and comparing the diversified monitoring data to select the optimal blasting schemes for the test sections. According to the method for evaluating the deep-buried tunnel blasting parameters, by implementing different blasting schemes in test sections with the same geological characteristics, diversified monitoring data of the test sections are obtained and compared to select the optimal blasting schemes for the test sections, so as to ensure the safety and quality of blasting excavation of deep-buried tunnels.
