摘要

FIELD: mining.;SUBSTANCE: invention may be used to perform explosive works with application of mixing-charging machines (MCM) for mechanised preparation of an emulsion explosive (EE) in process of charging of wells on opencast mining. The method includes EE preparation by injection of compressed air into an emulsion matrix, and then it is injected together with the emulsion matrix into a dynamic mixer-aerator. The mixer-aerator comprises at least two serially arranged mixing chambers, in which the EE is produced by aeration of the emulsion matrix with pressure increase in the mixer-aerator of at least 0.2 MPa. Aeration of the emulsion matrix is carried out to the value of distributed air gaps with size of 30-150 mcm at atmospheric pressure. The MCM is equipped with a compressor for air compression, and a mixer of components is made in the form of a coaxial, at least, double-stepped mixer-aerator of dynamic type, each stage of which comprises a rotor with axial blades and a stator with axial guide slots. On the manifold of finished EE supply downstream the mixer-aerator there is an accessory mounted to increase EE pressure in the mixer-aerator.;EFFECT: independence of sensitising process on emulsion temperature, cheapening of EE.
