Method and device for determining angle of blast hole, terminal equipment and medium

The invention is suitable for the technical field of mining, and provides a blast hole angle determining method and device, terminal equipment and a computer readable storage medium. The method comprises the steps that an initial angle set of blast holes of a target rock mass is obtained, the initial angle set comprises included angles between corresponding blast hole planes and the horizontal plane when the blast holes are located at different positions in the target rock mass; constructing a three-dimensional model corresponding to each included angle in the initial angle set by utilizing finite element analysis software; performing a blasting simulation test on the three-dimensional model corresponding to each included angle to obtain a rock mass damage map corresponding to each included angle; and determining a target angle of the blast hole according to the rock mass damage map. Compared with the prior art which only reduces the angle of the blast hole as much as possible, the method provided by the inve
