[0002] In recent years, with the continuous development of national infrastructure, deep hole blasting and single hole single blasting are often used in the construction of highway roadbeds, deep foundation pits, deep vertical shafts and other projects. The construction site is close to buildings, railways, high-voltage lines and other buildings (structures). The shock waves and vibrations generated by the blasting can easily have an adverse effect on their safety. Therefore, when using deep hole blasting for construction, it is necessary to adopt refined blasting and have stricter design requirements for various blasting parameters to ensure the safety of the protected objects.

[0003] When deep-hole blasting is used for open-pit engineering, the effects of drilling depth, mud plugging length, blasting footage, and topography on the distance R from the deep hole to the blast center cannot be ignored as in tunnel blasting. At the same time, the blast hole cannot be simply simplified into the blast center point to measure the distance from the blast center to the measuring point. This will make the fitting result of the Sadovsky formula inaccurate, resulting in large errors in the design parameters of later construction on site, and endangering the safety of nearby protected objects.
