Particle size composition of blasted rocks in tunnel driving and its automated determination Bayan Rakishev, Zaure Rakisheva, Asfandiyar Orynbay, Azamat Alibayev Tunnelling and Underground Space Technology, 2024 The article describes an analytical method for determining the particle size composition of the rock mass exploded by blasthole breaking of rocks in horizontal underground workings (tunnels). It is based on taking into account the size of the zones of intensive crushing of rocks around the blasthole charge and the presence of natural jointings in the rock mass. The radii of the zones of intensive crushing are calculated using the preset physico-mechanical properties of the blasted rocks and the physico-chemical characteristics of the applied explosive materials (EMs). The particle size composition of natural jointings is calculated using the average size of the jointing in the rock mass. Based on the combined consideration of these components, an analytical method has been developed for the first time in mining that allows to determine each rock class by size in terms of the blasted rock in the course of driving of horizontal underground workings (tunnels). A software program has been developed for the automated determination of the particle size composition of the blasted rock mass, which interconnects the influence of the physico-technical properties of the blasted rocks, the physico-chemical characteristics of the EM used, and the parameters of layout of charges in the rock mass. With this program, calculations were carried out in relation to the anticipated particle size composition of rocks under various parameters of drilling and blasting operations at the Zhezkazgan mines of Kazakhmys Corporation LLP. The comparison of the theoretical and experimental data types has demonstrated a high degree of their identity. These findings confirm that the proposed theoretical approach to determining the particle size composition of the blasted rocks takes into consideration the actual mechanism of destruction of the real rock mass by explosion in the course of driving of horizontal underground workings (tunnels). • Key result of blast in solid medium is blast cavity relative ultimate radius. • Cavity ultimate radius interconnects parameters and results of blasting works. • Main volume of intensely crushed rocks are formed at first stage of explosion. • Volumes of other rock cuts are formed at first and second stages of explosion. • Virtual grading of blasted rocks are formed at explosion second and third stages.
Control of blast parameters for high-quality breaking of thin slope ore bodies Yerdulla Serdaliyev, Yerkin Iskakov, Azamat Alibayev Mining of Mineral Deposits, 2024 Purpose. The research is aimed at substantiation of the effective method for mining thin slope ore bodies occurring in soft unstable host rocks by optimizing the breaking process, while determining the patterns of blast energy impact on the disturbed mass by explosive charges with controllable density, taking into account the geomechanical rock mass state. Methods. The research uses a comprehensive approach, including analysis of literature sources, practical experience of mining the slope ore bodies in difficult mining-geological conditions, modeling of the energy characteristics of blasts and wave action on the mass using software, as well as conducting experimental-industrial tests in the Akbakai mine. Findings. An innovative method for effective and safe ore mining from thin slope ore deposits in masses with weakened host rocks has been substantiated and developed. It implies the use of a new construction and location in the blast-holes of a charge consisting of mixed low-density explosives with widely controllable characteristics and with which the blast-holes are charged in two layers with different densities of explosives and detonated at different delay intervals. The optimum delay intervals have been determined, which improve the conditions for controlling the blast energy by changing the direction of the blast action vector towards the newly outcropped surfaces formed in the rock mass after the blasting the first stage charges. The main factors influencing the ore delivery range when mining thin slope ore bodies with blast delivery system have been revealed and methods for increasing this process efficiency are proposed. Originality. New parameters of drilling and blasting operations have been determined for the conditions of mining thin slope ore bodies of the Akbakai deposit: a rational charge construction with controllable blast characteristics has been deve-loped; the optimum range of blast-hole charging density with mixed low-density explosives and delay intervals have been substantiated; a new exponential dependence of the ore delivery range on the specific blasting agent consumption and the angle of the ore body occurrence has been revealed. Practical implications. Practical significance is in increasing the efficiency of blast breaking of minerals, improving the quality of blast delivery of broken ore to loading sites while maintaining the host rock mass continuity and reducing the ore mass dilution, eliminating the formation of large-sized pieces that complicate the blast delivery of the broken ore.
