The announcement that further coal mining is required to meet demand comes after the country's Minister of Coal Pralhad Joshi said in March that India will have enough coal reserves to begin exporting by 2026, a move that will see the nation move from being a net importer to a net exporter of coal. In May, the ministry also announced …

The experiences and benefits gained by the Australian coal mining industry have been adopted in other coal basins of the world to make mining safer and more productive [23,24]. Figure 1.
This method can determine the mass of silica particulates in respirable coal mine dust. The airborne particulates are collected on filters, i.e. polyvinyl chloride (PVC) using calibrated sampling pumps. This method provides for a sample preparation using a low temperature ashing procedure.
A common practice of sampling thick coal beds (greater than 10 m thick), either by core or by channel, is to divide the bed into intervals no thicker than 1.5 m. In many cases, thick …
All coal mine discharge downstream samples had concentrations of sodium from 270 to 800 mg/L, while upstream samples had concentrations ranging from 29 to 44 mg/L indicating very low background levels and a substantial impact of the release of salts from the coal mine produced water. Elevated level of sodium, sulphur, barium, lithium …

As the depth and intensity of coal mining increase, accidents involving coal or rock dynamic disasters such as rock burst, coal and gas outburst, roof collapse, and water inrush become more serious (Li et al. 2016a, b; Wen et al. 2015, 2016).Although the ground motion caused by rock burst is smaller than that generated by earthquakes, rock …
coal is based on the analytical results. Coal is a very heterogeneous material containing various organic matter and inorganic (mineral) matter, and exhibits a wide range of physical properties. The analysis of coal is generally performed on the coal samples taken from
The federal government has been directly involved in coal mining safety for over 35 years, operating under three major pieces of legislation, enacted in 1941, 1952, and 1969. Opposing opinions regarding the effect of this legislation can be grouped into three categories: radical, reactionary, and reformer.
