Purpose – This paper aims to define and theoretically analyse the performance of modern methods investigated to speed up the recultivation process of degraded areas, and apply it into the mining basin, open pit mines, tailings and all other areas, which need environmental quality improvement. Design/methodology/approach – This paper presents methods of conservation and substitution of natural resources for the purpose of faster land recultivation (reclamation) in degraded coal mine areas. Two types of methods have been developed: forest slope recultivation and agricultural recultivation of flat landfills. Indicators of positive changes include: changes in chemical properties of tailings, increase in biogenic properties and changes in biodiversity. Findings – The research results show that the application of these methods, along with the holistic approach and adequate investment, can significantly contribute to the length of recovery process and accelerate it. Research limitations/implications – Mining basin Kostolac is used as a model test. The results can be applied on all mining basin, open pits and any degraded area. Originality/value – All results and conclusions were drawn, based on the original measurements and experiments. Stake holders, wanting to manage environmental quality after exploitation in mining basin, applying those methods, can find the value of this paper.

Traceability System

PurposeAccording to United Nations reports, the worldwide population is expected to reach around 9.6 billion by 2050. This forecasting emphasizes the role of phosphate-based fertilizers for developing sustainable agriculture and ensures the demand all over the planet. From this perspective, phosphate companies are racing to improve their industrial performance and guarantee the quality, reliability and integrity of information efficiently. The purpose of this paper is to propose a traceability system framework that ensures product quality tracing and real-time operations monitoring for open-pit mines.Design/methodology/approachThe authors develop a hybrid approach that integrates Business Process Model and Notation techniques with System Modeling Language to formalize several use cases and scenarios to model quality traceability processes related to open-pit mines. This framework also embeds an optimization module based on mathematical modeling approaches to optimize stockpiles’ movement and respect the distinction between different qualities.FindingsThis paper explains a successful implementation of a quality traceability tool for an African mining company. The research team was able to understand and scale down the problem faced by the managers. Further, the study is focused on improving quality tracing over time and automatizing the current compliance processes related to the mine extraction activities. The proposed tool is proved highly effective in reducing the time of tracing quality claims by 46% compared with the manual procedure. Second, the implementation of this tool reduced fuel costs by 34% and CO2 emissions by 10%.Originality/valueThe originality of the contributions lies in four aspects: (1) adapting quality traceability concept for the mining industry; (2) assessing the current trends of traceability systems considering the mining industry context; (3) hybridizing business processes re-engineering, quality system and optimization modeling; and (4) using a real case study of a phosphate company to evaluate the framework.

Subject Mining companies rediscover innovation. Significance The prolonged slump in commodity markets has forced mining companies to focus on cost control. Firms responded first by cutting sustainable capital and refocusing production on high-grade areas. Now the industry is turning to lower-quality, shorter-life deposits, requiring innovation and the embrace of radical technological breakthroughs to extract additional profit margin. Impacts Fleets of autonomous mining trucks will change the design of ramps in open-pit mines, improving economic optimisation and safety. Certain bulk commodities are becoming amenable to more environmentally friendly and nimble forms of containerised transport. Durable fabric structures for storage, maintenance and employee accommodation will replace brick-and-mortar structures at remote sites. The advent of optical ore sorting and other forms of pre-concentration will reduce unnecessary processing of waste material.

Significance The new rules remove corporate tax, but hike mining royalties to 20% for open pit mines (up from 6%), and 8% for underground mines (also up from 6%). Some flexibility in the payments schedule may be permitted. Impacts The collapse of the opposition MMD's support base means business lobby funding and support is likely to shift to Hakainde Hichilema's party. Following his declared support for the PF, Rupiah Banda's moderating influence on party policy may be limited by his outsider status. The IMF will be wary of confirming a fiscal consolidation programme, given the president's short tenure and his populist platform. Lower fiscal revenues from mining may push the government to borrow further to meet its election campaign promises.

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.
