Abstract
For effective production of drilling and blasting operations and improving the quality of crushing of the rock mass, it is necessary to take into account its structural properties. Determining blockiness in a flat setting can lead to significant errors in their sizes, which leads to the formation of a coarse fraction after the explosion (oversized pieces) or excessive waste of explosives. In this regard, the use of unmanned piloting technologies and the photogrammetry method seems promising, allowing for a more competent approach to the issue of assessing the size of blocks of rock by analyzing volumetric shapes. The approach in determining the blockiness size of the massif by analyzing all the exposed surfaces of one block has improved the quality of the crushing of the massif.
