Erdenet copper-molybdenum deposit is the biggest one in the world and has a significant impact on Mongolian society and economy. Today LIEBHERR-994B hydraulic shovels from Germany, electric shovels including EKG-10 and EKG-15 from Russia operate for the mining works, and dump truck BelAZ - 75130 used for transportation. The causes of shovel downtime are classified as technical, technological, and organizational. During the study period, 41% of the total downtime of the excavator’s park was technical, 45% was technological, and 11% was organizational downtime. For shovels, 7% of technological downtime is due to blasting, and for dump trucks 8.7%. In open-pit mining, blasting is performed on a weekly basis, so the duration of this technological downtime can be considered almost constant. If the time between blasts or period of blasting can be arranged optimally, it will be possible to reduce mining equipment’s downtime due to blasting.

The paper considers the expediency of complex processing of zeolite-smectite tuffs using the method of borehole hydro-mining. The basic information about deposits of zeolite-smectite tuffs in the Rivne-Volyn region of Ukraine and the main areas of their application in industry are presented. Also, the method of calculating the parameters of the process of hydraulic erosion of tuffs and underlying rocks by the method of borehole hydro-mining is given, and the dependence of the specific consumption of the working agent during erosion of tuffs and underlying rocks on the diameter of the nozzle at variable pressure is presented. The dependences for determining the rational forms of recess chambers with the specified erosion radius are given.

“…A significant task of subsoil geometrization consists in increasing efficiency of drilling and blasting as an important factor for mining enterprise performance [28][29][30][31][32]. This task, in turn, is associated with that of monitoring the state of the rock massif [33][34][35][36][37] and closely related to methods of mining processes control [38][39][40][41][42].…”

Mining and geometrical prediction of iron ore deposit quality indices to solve problems of long-term and current planning intended to provide the most efficient performance of mining enterprises in terms of ore blending quality and increase rationalization of deposit development is an important aspect of geometrization. Investigations carried out to develop a mining-geometrical method for predicting indices of iron ore deposit quality are topical nowadays. The present study aims to enhance the methodology for geometrization of iron ore deposit quality indices for developing a mining-geometrical method of their prediction to provide rational mining. The research methodology consists in mining and geometrical modeling of quality indices and properties of the deposit, thus enabling determination of a certain relationship between components of a mineral, and, thereby, identification of the nature of these components’ location in the mineral. The latter is essential in design, construction and operation of a mineral deposit. The obtained results allow predicting quality indices of the deposit, assessing mineral reserves and consequently planning and optimizing performance of mining enterprises. The developed methods enable increased efficiency of mining iron ore deposits of Kryvbas.
