Abstract (sommario):
Occupational exposure limits for respirable coal dust are based on exposure during working hours, but coal miners may experience additional community-based exposures during nonworking hours. We analyzed Australia National Pollutant Inventory (NPI) data for the years 2008–2018 to estimate air pollutants (metals, nitrogen oxides, particulate matter ≤ 10 micrometers (PM10) and ≤2.5 micrometers (PM2.5)) originating from coal mines. PM10 levels from community-based air monitors in Queensland and New South Wales were also compared between mining and nonmining communities. Results indicated that tons

Abstract (sommario):
Coal mining in China is facing the transition from output to quality. Based on the total mining capacity and average production, the current situation of coal mining at mine, city, and province levels is analysed, and data in support for the layout of sustainable mining development and the optimization of output provided. The results show that 87% of China's coal is mined by underground methods, with an average production capacity of 0.93 Mt/a per mine. Open pit mining accounts for 13%, with an average mine production capacity of 5.73 Mt/a. The average mining capacity of coal mines in China is

Abstract (sommario):
Abstract Numerous underground coal mines were in operation in the Borsod coal basin in northeastern part of Hungary until the beginning of this century. The main area of utilization of the mined out coal beside power and heat generation was supplying households with fuel mostly for heating. In the beginning of the 1990ies the power plants in question were shut down for economic, environmental and technical reasons. Consequently all the mines were closed no later than 2004 and thousands of miners lost their jobs. A new perspective of coal mining can be enabled by other ways of utilization of co

Abstract (sommario):
Future development of mining operations along with creation of new mines, will be supported by modernization and reconstruction of existing enterprises. Creation of mechanized coal face systems that ensure complete extraction of coal reserves with the supply of occupational safety is prospective. One of the most effective technologies for the development of high coals is their mining from wall to wall with drawing coal from the roof layer into the under-cutting layer. Research of a new design of mechanized support was carried out using the developed simulation model based on the discrete eleme

Abstract (sommario):
Coal is mined by both surface and underground methods and its extraction is normally characterized by numerous hazards that can lead to catastrophic accidents, which result in devastating effects such as injuries or fatalities, damage to mining assets, and destruction of mineral resources. These hazards exist due to the ability of coal to support combustion and its association with toxic, flammable, and explosive gases. Underground coal mining entails higher safety risks than opencast coal mining, chiefly because of issues relating to mine ventilation and mine collapse. Furthermore, coal mine

The Kemerovo Region is the leading coal cluster of Russia and Europe, where about 60% of all domestic coal is mined, 42 mines and 51 open-pit mines are operating, as well as 54 coal processing plants and installations. At the beginning of 2019, more than 90 thousand people worked in the coal industry of Kuzbass. The task of increasing the labor productivity of coal enterprises is largely determined by personnel potential, which is the main productive force in the post-industrial era.

The unsafe behavior of miners seriously affects the safety of deep mining. A comprehensive evaluation of miners’ unsafe behavior in deep coal mines can prevent coal mine accidents. This study combines HFACS-CM, SEM, and SD models to evaluate miners’ unsafe behaviors in deep coal mining. First, the HFACS-CM model identifies the risk factors affecting miners’ unsafe behavior in deep coal mines. Second, SEM was used to analyze the interaction between risk factors and miners’ unsafe behavior. Finally, the SD model was used to simulate the sensitivity of each risk factor to miners’ unsafe behavior

Abstract (sommario):
ABSTRACT Induced seismicity is common in underground mining, particularly in mines that cave by design, such as longwall coal mining. Seismic monitoring is one of the few remote sensing technologies that provide an understanding of a mine's response to extraction. However, its effectiveness usually depends on understanding event locations in relation to the mine workings. A significant source of uncertainty in event locations is the velocity model: a description of the speed at which seismic energy propagates. A nondestructive, repeatable compressed load column seismic source (CLCSS) was devel

Abstract (sommario):
In underground coal mines, miners face the hazard of being struck or pinned by a piece of mobile mining machinery. Proximity detection systems have been developed and are used by the industry to protect miners around these machines by detecting the presence of the miners and automatically issuing warnings or disabling machine motion when a miner is in potentially dangerous proximity. These systems were originally developed for continuous mining machines, slow-moving machines that move on bulldozer-style tracks, and are now mandated by the Mine Safety and Health Administration (MSHA) to be used

Abstract The implementation of low-permeability barriers was originally proposed to reduce gas influx into areas of pre-drainage prior to or after mining operations (Johnson Jr, 2014). Currently, barriers are being proposed to provide a real opportunity to dramatically reduce methane emissions from open-cut, metallurgical coal (MC) mines, essential to meet steel production targets for international urbanisation and energy transformation. Finally, barrier implementations can accelerate peak gas production and recovery in areas of undersaturated coals or coal wells subject to aquifer influx. The

Abstract (sommario):
Hypothesis and Objectives: We hypothesized that coal combustion products (CCPs), including those created during scrubbing of sulfur dioxide from flue gases, can be used alone or mixed with composted animal manures as effective growth media for plants. Our specific objectives were, therefore, to (1) measure the chemical, physical and hydraulic properties of source materials and prepared mixes, (2) determine the optimum design mix of CCPs and composted animal manures for growth of plants, (3) evaluate the leachate water quality and plant uptake of selected elements from prepared mixes, (4) quant
