In summary, a comprehensive LCA study on the environmental impacts of coal mining in China is still lacking. Therefore, this study aims to (1) analyse the environmental burden of a typical underground coal mine in China using the LCA
The analysis result shows that the carbon emissions of producing tons of coal are 164.403 kg of carbon dioxide equivalent per ton. The analysis further
Coal is not only the main fossil fuel in China but also a pollution source. To evaluate the impact of coal production on the environment, a life cycle assessment (LCA)
The proposed model enables the assessment of greenhouse gas emissions (GHGs) based on the IPCC method and the assessment of damage
In 2008, the coal production has reached 2.72 billion tons. Longtime and intensive mining has caused spatiotemporal cumulative effects on soil, water, air
underground mining (room pillar, long wall, drift, shaft, slope mining) are some types of coal mining. Proper Environment impact assessment of coal mining is very

This study is pursued to assess the impact of coal mining activities on local community and environment. : Environmental problems of underground coal mining in India : Suspended particulate matter
coal mining is considered to be the most hazardous occupation in the United States (Coal Commission, 1980 in Hayduk and R itzel, 1988). Table 1.1 Occupational accidents and diseases for selected

Coal is China’s main source of energy, and its production causes a certain degree of air, water, and land resource pollution. Therefore, it is necessary to compare environmental pollution caused by different mining methods. When mining underground coal resources, different mining methods have different levels of environmental impacts. To
Coal is not only the main fossil fuel in China but also a pollution source. To evaluate the impact of coal production on the environment, a life cycle assessment (LCA) was conducted on the mining process of a typical coal mine in China by using the SimaPro 9.0.0 software. The Ecoinvent v3 database w
Coal mining, the first step in the filthy lifecycle of coal causes deforestation and releases toxic amounts of minerals and heavy metals into the soil and water environment. Coal mining's environmental effects persist for years after coal is removed.Based on the latest technologies on coal mining practices are better than what
Underground coal mining consumes a large amount of electrical energy to run the equipment such as ventilation fan, pumping/dewatering, belt conveyors, rope haulages, face machinery, and illumination. Underground coal mining has less production and high output cost (cost per unit of coal production) due to the low effective utilization of equipment and
Coal mining has caused groundwater pollution and loss. Using a mined area as a water storage space for storing and purifying mine water is a lowcost environmentally friendly mining method. In this study, static and dynamic adsorption experiments on the ions in mine water were carried out using the roof rocks from the
In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable
As an effective groundreinforcing system, rockbolts have been widely used in underground excavations. Corrosion of rockbolts has been one of the most reasons for rockbolts system failure. In this paper, the chemical composition and pH values of the groundwater in Sanshandao Gold mine are first tested. Corrosion of the slotted rockbolts

A national environmental group has filed an appeal to the province of Nova Scotia, calling for Canada’s only underground coal mine's recent approval to be overturned. Sierra Club Canada’s Atlantic chapter argues the industrial approval granted to the Donkin coal mine in Cape Breton should be overturned because it violates the province's

With the increase in depth of coal mining, the hydrogeological complexity largely increases and water inrush accidents happen more frequently. For the safety of coal mining, horizontal directional drilling and grouting techniques have been implemented to detect and plug the fractures and conduits that deliver highpressure groundwater to coal
The Underground Coal Mines sector consists of all underground coal mines that liberate 36,500,000 actual cubic feet of methane (equivalent to approximately 17,579 metric tons CO 2 e) or more per year. Facilities in this sector include both underground coal mines under development and those categorized by the Mine Safety
Coal mining at Mchuchuma will originally involve surface miningwhich will be undertaken for 3 to 5 years with a capacity of 1.8 million tons/annum via opencast technology. Coal will be fed into thermal power plant during the transition to underground mining with a capacity of 3.0 million tons/annum.
Coal mining played a supportive role as provider of energy to the growing gold mining industry and indeed, many collieries were historically and are today owned by gold mining companies. To these coal mine owners it was more important to keep the costs of their own energy inputs low, than to profit from coal mining itself4. The coal
