Abstract: The sphere and conditions for application of the water-in-oil type of emulsion explosives in deposits of the Southern Urals and Kuzbass have been justified. Two sub-classes of these types of emulsion explosives are defined depending on the main components used at the final stage of their production (a blast hole or mixing and charging machine) with or without addition of dry ammonium nitrate. Diagrams of semi-stationary and mobile technological complexes have been justified for production of emulsion explosives. A rationale was provided for the selection of the competing methods to produce and deliver emulsion explosives using the case of UK Kuzbassrazrezugol JSC with account of technological and economic factors. Three competing options were considered: (1) a stationary or semi-stationary technological complex to produce emulsion explosives; (2) a stationary technological complex based on the existing plant of Nitro Siberia-Kuzbass JSC (Kemerovo) under an outsourcing agreement; (3) a mobile technological complex as a case of partial outsourcing to the Nitro Siberia-Kuzbass JSC plant. Comparison of the competing options helped to identify the third option as the priority. In this option the cost of emulsion explosives is affected by the cost of basic components at the chemical plant; depreciation of the self-propelled component delivery vehicles (10-15 vehicles); operating and maintenance costs of the delivery vehicles; rental of the mixing and charging machines (1-2 vehicles) to produce and charge the emulsion explosives. After covering the capital expenses (1-1,5 years) there will be a reduction in cost up to 20% as compared to the second option.
