| Abstract: | In order to ensure the safety and stability of the underground tunnel under blasting vibration,the blasting vibration was monitored with Blastmate Ⅲ vibration measurer in the production site of Tongkeng mine.Based on the test results,the stability of the underground tunnel was evaluated with comprehensive coefficient method,a calculation formula of Maximum charge in one delay time for ensuring the stability of underground tunnel under different comprehensive coefficient K-value was presented,and appropriate blasting methods and supporting pattern were proposed.The evaluation method and conclusions are of reference value to some similar mines. |
