Control of density and velocity of emulsion explosives detonation for ore breaking

Purpose.Development of a new procedure for calculating the density emulsion explosives (EE), that will allow determining detonation velocity along charging length, depending on inclination boreholes during ore breaking. Methodology.A calculation method redistribution EE and mass in at different angles has been developed by using well-known laws hydrostatics. Measurement Ukrainit-PP-2B was conducted polygon experimental tests. The numerical simulation changes proposed established regularities. Findings.Methods changing column length under action hydrostatic pressure both ascending descending have developed. Based data, regularities rate from charge diameter Ukrainit-PP-2B, varying according to exponential law established. rational initial ores breaking boreholes, which is equal 8001000 kg/m3, maintained. obtained results controlling Originality.The increases formed pressure: face, while brow. Practical value.Application makes it possible determine sections with its critical values more than 1410 sharp attenuation begins. Consideration this phenomenon prevent occurrence failures explosion charges
