В статье приводятся результаты палинологических исследований археологических объектов бронзового века в районе Ишкининского медного рудника: разреза на поселении Ишкиновка и погребенных почв, сохранившихся под отвалами карьеров. Палинологические исследования образцов с поселения Ишкиновка позволили получить информацию о характере формирования культурного слоя поселения, образование которого связано с руинированием саманных построек с органическими перекрытиями. Особенности строительных материалов предопределили сложный многокомпонентный состав палинологических комплексов. Результаты палинологических исследований на Ишкининском руднике и поселении Ишкиновка хорошо согласуются с реконструируемой моделью их функционирования, в соответствии с которой выделяется не менее трех этапов разработки Ишкининского месторождения на протяжении ПБВ. Каждому из выделенных хронологических этапов соответствует самобытный палинологический спектр, отражающий динамику природно-климатической ситуации в районе исследований. Эти данные надежно верифицируются результатами радиоуглеродного датирования погребенных почв, законсервированных под отвалами карьеров. The paper describes the results of palynological studies of Bronze Age archaeological assemblages discovered within the Ishkinovka copper mining center, i. e. the section at the Ishkinovka settlement, and the buried soils preserved under the dumps from the open-pit mines. Palynological studies of the samples from Ishkinovka helped obtain information on how the occupation layer at the settlement was formed. Its formation is linked to ruination of mudbrick constructions with organic roofing. Distinctive features of the construction materials predetermined a complex multi-component composition of palynological assemblages. The results of the palynological studies at the Ishkinovka mining site and the Ishkinovka settlement correlate well with the reconstructed model of their operation. At least three stages of the Ishkinovka deposit development during the Late Bronze Age have been singled out. Each identified chronological stage corresponds to a distinctive palynological spectrum reflecting changes over time in the natural and climatic situation in the studied region. These data are reliably verified by the radiocarbon dating of the buried soils preserved under the dumps of the open-pit mines.

Chernogosky open pit mine integrates truck-and-shovel system of mining with overburden rehandling to internal dump with a set of walking excavators for rehandling of overburden to mined-out area of the pit. It is possible to improve efficiency of stripping in the conditions of Chernogorsky OPM by reducing percentage of stripping with more expensive handling system. The relevant research and solutions to this effect are presented in this article. Comparative characterization of mining conditions and parameters of mining systems applied is given for open pit mines Chernogorsky, Turnui, Nazarovsky, Vostochno-Beisky and Izykh. The comparative analysis points at the need to account for difficulty of mining and process sites in comparison of equipment productivity. High concentration of mining machines, which is conditioned by narrow mining front and simultaneous operation of five faces, as well as blasting operation implemented every 1-2 days, are recognized as the main constraints of excavator capacity in mining with direct dumping in Chernogorsky open pit mine. The management and engineering solutions implemented in the mine and resulted in higher efficiency of draglines are described.

This research article presents a software module for the environmental impact assessment (EIA) of open pit mines. The EIA software module has been developed based on the comprehensive examination of both country-specific (namely, Kazakhstan) and current international regulatory frameworks, legislation and EIA methodologies. EIA frameworks and methods have been critically evaluated, and mathematical models have been developed and implemented in the GIS software module ‘3D Quarry’. The proposed methodology and software module allows for optimised EIA calculations of open pit mines, aiming to minimise the negative impacts on the environment. The study presents an original methodology laid out as a basis for a software module for environmental impact assessment on atmosphere, water basins, soil and subsoil, tailored to the context of mining operations in Kazakhstan. The proposed software module offers an alternative to commercial off-the-shelf software packages currently used in the mining industry and is suitable for small mining operators in post-Soviet countries. It is anticipated that applications of the proposed software module will enable the transition to sustainable development in the Kazakh mining industry.
