SCCL has established a separate Environment Department for continuous monitoring of compliance of environmental norms in coal mines and develop suitable mechanisms
The mining industry is an integral part of human life, as miners extract a variety of resources including coal, iron ore, diamonds, platinum, and gold. In the early stages of civilization, basic tools were formed using stones and metals found near the earth's surface.
Ventilation control of dust in coal mines is important in the different types of underground coal mining such as (1) room and pillar mining, (2) longwall mining and (3) shaft mining. Type (1) is done in an ore deposit where some of the ore is left behind to form columns in the mine that prevents it from collapsing and it is used for coal mining.
Coal, as one of the vital sources of energy in China, has raised widespread concerns regarding its safety issues amidst the country's economic growth driven by coal. To address this concern, this study employed the Kuznets curve, multiple linear regression, and data envelopment analysis models to investigate the impact of Chinese coal …
Improving the emergency response effectiveness of coal mines in response to water hazard accidents not only plays a vital part in minimizing the resultant losses, but also functions as an important index for evaluating the emergency response capability of coal mines. Therefore, it is of great necessity to test the emergency response capability …
This article reviews evidence for the public health impacts of coal across the extraction, processing, use, and waste disposal continuum. Surface coal mining and processing impose public health risks on residential communities through air and water pollution. Burning coal in power plants emits more nitrogen oxides, sulfur dioxide, particulate …
