Influence of mining-geological conditions and technogenic factors on blastholes stability during open mining of apatite-nepheline ores

The paper presents the results of borehole stability research and considers possible causes of emergencies. The features of the blast hole drilling process are analyzed taking into account the properties of the rock. Based on the distribution of speed of drill fines removal from the well, an algorit...
