Occupational accidents in the Spanish mining industry have been substantially reduced over the last decades. However, the incidence rate shows higher values than other leading mining countries. In this regard, the research carried out reveals the factors influencing the high incidence rates of the Spanish mining sector, based on three scenarios: underground mining (UG), quarries and open pit mining (OP) and mineral processing plants (PP). The three most common types of accident for each scenario have been determined, considering the accidents in Spain between 2009 and 2018. The analysis also includes the main deviations, and physical activities that the injured worker was carrying out at the time of the accident. Besides, a model to predict the number of accidents based on the lost working days is also presented together with the incidence and severity risk index adjusted by the number of employees and their worked hours, respectively, in each scenario. These finding can be relevant to define the most effective measures and policies to reduce the number of accidents in the mining sector.

Open mining development is the cheapest method, because it uses powerful production equipment, which allows a large amount of minerals to be excavated during a shift. Working conditions in open development are less dangerous for the health of workers, and a smaller number of supervisory personnel than in underground mining is required. In the process of open development, stripping works are first carried out, i.e. the removal of the empty rocks covering the deposit. Constantly growing requirements for energy sources, metal ores and building materials cause the need for intensive development of the mining industry. There is a rejection of significant areas for the development of minerals in an open and closed way. The causes of degradation are both the mining of minerals, as well as construction, the placement of production and consumption wastes in the natural environment. Changes in the components of the environment are observed as a result of direct or indirect influence of mining enterprises activities. This requires an analysis of the entire complex of geo-environmental problems of open mining and the identification of the most urgent ways to solve them.

At present time,Mozambiqueis called the “Rising Star of South Africa” mainly due to the rapid development of its mining industry. Mineral resources sector ofMozambiqueis one of the most dynamically developing sectors of the country’s economy.China,BrazilandIndiahave recently become the main partners forMozambique. Recently, a number of projects is being implemented in the country, for example, Auroch Minerals Manica Gold in gold production. Increasing coal production is connected with commissioning of the Moatize open pit, which is being developed by Brazilian Vale Company, as well as Benga mining company owned by Indian ICVL consortium. The analysis of the extraction of certain mineral types inMozambiquepresented in the paper demonstrates general picture of mining industry development in the country. The analysis findings allow identifying the causes of negative phenomena in the industry, manifesting themselves in decreasing production of certain types of minerals. For instance, the main reasons for the decline in coal production were dropping labor productivity, deterioration of mining conditions, and depletion of the most accessible coal reserves, extractable by open pit mining. In this regard, development of underground mining methods providing for opening of deep deposits by vertical shaft sets is highly relevant. The experience of the neighboringRepublicofSouth Africashows that, in the mining and geological conditions of the south of the African continent, highspeed shaft sinking methods accelerating deposit development can be successfully applied.

Large-scale mining disturbs wide areas of land. The development program for the mining industry, with an expected considerable increase in production output, aggravates the problem with even vaster territories exposed to the adverse anthropogenic impact. Recovery of mining-induced ecosystems in the mineral-extracting regions becomes the top priority objective. There are many restoration mechanisms, and they should be used in integration and be highly technologically intensive as the environmental impact is many-sided. This involves pollution of water, generation of much waste and soil disturbance which is the most typical of open pit mining. Scale disturbance of land, withdrawal of farming land, land pollution and littering are critical problems to the solved in the first place. One of the way outs is highquality reclamation. This article reviews the effective rules and regulations on reclamation. The mechanism is proposed for the legal control of disturbed land reclamation on a regional and federal level. Highly technologically intensive recovery of mining-induced landscape will be backed up by the natural environment restoration strategy proposed in the Disturbed Land Reclamation Concept.

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.

The intensive process of economic growth and job creation in Brazil in the last years is often associated an important dimension where this process is far drop satisfactory: the high incidence rates of occupational accidents. Important instruments can be constructed from the quantitative study considering possible changes caused by economic dynamics over the years. We conducted exploratory spatial data analysis  (ESDA) and Local Indicators of Spatial Association (LISA) to analyze the spatial distribution of this rate in order to identify critical regions in Brazil. Data were extracted from the Brazilian Ministry of Labor and Employment (MTE) and from the Brazilian Ministry of Social Security websites for the years from 2002 to 2012. Results show that the incidence rate of occupational accidents in Brazil is distributed in a geographically non-random manner and municipalities with high rates tends to cluster.

Analysis of the grade composition of the mineral resource base of the distributed and undistributed subsoil Fund as of 01.01.2018 showed a decrease in reserves of coal intended for open pit mining. In the future, the production of a number of technological grades of coal (gas fat (GZh), fat (Zh), coking fat (KZh), coking (K), coking caking low-metamorphized (KCN), coking caking (KC), lean caking (OC), low caking (CC) is possible only by underground method. The expansion of the raw material base of the Kuzbass coal industry and the support of coal production volumes, primarily by the technological of grades coking fat (KZh), coking (K), coking caking (KC), lean caking (OC), low caking (CC) involves exploration, the use of unconventional production technologies and tax preferences for coal mining enterprise

Significance On the agenda is the issue of legislation on open-pit mining and the stopping of the export of unprocessed ores. This follows Cimatu’s confirmation in post by the Commission on Appointments on October 4. Previously acting secretary, Cimatu replaced the controversial Regina Lopez, who was not confirmed as environment secretary earlier this year. The Philippine mining industry was wary of Lopez’s pro-environment, anti-mining policies, and now wants to see what Cimatu’s plans are. Impacts Under Cimatu, mining firms could gain more opportunities to engage with policymakers. Environmental and anti-mining groups will see Cimatu’s appointment as a betrayal; protests are possible at mining projects. Peace in Mindanao would unlock an estimated 1 trillion dollars in untapped mineral resources.
