Dust control in underground as well as open pit mines has been an area of intense research and study. Dust controlling by dust capturing or dust consolidation and using appropriate method for different causes of dust generation has been the concern of this paper. Dust is generated mainly in every activity of mine from drilling to transportation to using any modern mechanization for ore extraction. Dust generation can cause less visibility more accidents, breathing problem, affects agriculture and vegetation. Various methods deployed for its control and separation does not impact its originator rather reduces its percentage in mine air. Wet drilling, water spraying, ventilation, dust collector and air flow to control the generation of dust have proven profound impact to control dust. This paper embeds the detailed causes of dust, how dust can be reduced in mine air and what can be done to prevent it, if possible.

The practice of dust control on coal mines and technological roads both in Russia and abroad shows that reducing dust content, to the maximum permissible concentrations is a very difficult engineering task. To combat dust in open pit mines, various methods and techniques are used. The study of progressive dust control agents will allow normalizing sanitary and hygienic conditions at mining enterprises, and reducing the level of occupational diseases of miners. The article deals with the types of dust and the fact that a large amount of dust accompanies the processes of extraction and transportation of coal from the open-cast to the concentration plant. The experience of dust control at the enterprises of Joint Stock Company Siberian Anthracite is given.

Mining activities are usually associated with environmental impacts, particularly that of air pollution by fugitive dust. Malmberget mine is one of the most important iron mines in Sweden and the dust problem has been noticed by the inhabitants for a long time. Dust collectors had been installed to measure the dust fallout around the mining site. In this research the dust fallout recorded during the period August 2006 till July 2010 were analyzed. Generally speaking the amount of dust fallout was decreasing year by year due to some implemented dust control methods. Mining activities produced more dust during summer than winter. The peak value was 265g/100m2/30d appeared in May 2007, and the lowest dust fallout was 25g/100m2/30d happened in August 2009. Dust was determined to be originated from the open pit area and the industrial center area. Truck transportation on the haul roads, wind erosion of stockpiles and exposed areas were the main activities that caused dust generation.

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.
