| Abstract: | In order to optimize the blasting parameters in No.92 orebody of Tongkeng mine,the single hole blasting crater test,contrast tests on hole-net parameters and millisecond delay interval were carried out.Blasting parameters of 65 mm flabellate moderate-long holes were ultimately recommended by analyzing as follows: the explosive consumption is 1.168 kg/m3,the minimum resist line is 1.2 m,the interval of holes is 1.5 m and the millisecond delay interval is 50 ms. |

| Keywords: | flabellate moderate-long hole blasting crater millisecond delay interval hole-net parameter |
