Extraction of valuable components by flotation and magnetic methods from tails of gold extracting factories

This article reviewed and analyzed the study of performance and efficiency of exchange-loading equipment. Despite a number of previous studies in this area, many issues require further in-depth study. In particular, the influence of operational factors on the nature of the total resistances overcome by the drive for the use of excavation and loading equipment has not been sufficiently studied, the dependence of the change in the power component of the diesel load mode during the technological cycle and its influence on the energy intensity of the process have not been determined.

“…Based on the analysis of the previously given methods for calculating the destruction zones, it can be noted that they all work under certain conditions. In addition, a number of techniques are applicable only to monolithic arrays [20][21][22][23][24][25][26][27][28][29].…”

Methods for calculating the parameters of drilling and blasting operations based on the primary determination of the zones of destruction of the rock mass

The article considers the dependences of determining the parameters of the destruction zones of the rock mass by explosive charges, proposed by V.N. Mosints, N.P. Gorbachev, M.F. Drukovanny, V.N. Tyupin, B.N. Kutuzov and A.P. Andrievsky and others. The above dependences allow determining the location of the boreholes in the face, taking into account the physical and mechanical characteristics of the massif being destroyed, the features of the explosive used, the variety of mining, geological and mining technical conditions for driving mine workings, as well as performing the calculation of rational parameters under conditions of increased rock pressure.

“…In these cases, the increased speed of the rock mass will contribute to the growth of the efficiency of blasting. It should be noted that the speed of movement of broken rock mass during short-delayed blasting of several layers is always lower than during simultaneous instantaneous blasting under similar conditions [30][31][32][33][34][35][36][37][38][39][40][41][42].…”

Investigation of the Process of Destruction of a Roain Massif by Borehole Charges with an Axial Air Cavity by the Method of Physical Simulation

the design of downhole explosive charges with an axial air cavity was developed, which ensures uniform crushing of the rock mass and reduces the specific consumption of explosives. A technique has been developed for modeling the process of destruction of a rock mass by borehole charges with an axial air cavity. It has been established that with an increase in the diameter of the axial cavity, the mass of the charge and the specific consumption of explosives for breaking decrease. However, this decrease occurs only up to a certain limit, after which the volume of the chipped mass decreases and the specific consumption of explosives increases. The most efficient way is to reduce the specific consumption of explosives for breaking when the ratio of cavity diameters and charge diameters is 1.3:5–2.2:5. For other values of the ratio, the specific consumption of explosives increases dramatically.
