According to the complexity of the environment in the blasting area of the block field around the fresh water well, the deep hole blasting technology was chosen with applying regular triangle hole arrangement and composite blasting network and optimizing blasting millisecond time and stemming length. The engineering practice showed that the blasting results were satisfactory and the blasting vibration and flyrock were controlled as expected.
