Abstract Of Coal Mining
Abstract.Coal mining under conditions of sufficiently high pore gas pressure can produce the hazard of dynamic failure of coal known as coal and gas outbursts.During an outburst, coal fragmentation occurs and the fragmented coal is projected into the mine opening, accompanied by a rapid release of gas.

15/10/2020 Abstract. This paper examines economic impacts of coal mining across local government areas (LGAs) in Australia. Three main distinguishing features of this research are a) the analysis through the mining boom and bust cycle, b) a focus on small regional areas within one state in Australia and c) the use of socio-economic indicators in addition to the standard income and employment indicators

Environmental impact of coal mining and coal seam gas
Abstract The extraction of coal and coal seam gas (CSG) will generate produced water that, if not adequately treated, will pollute surface and groundwater systems. In Australia, the discharge of produced water from coal mining and related activities is regulated by the state environment agency through a pollution licence. This licence sets the discharge limits for a range of analytes to

Constraints of coal mining safety management efficiency
Abstract Background: Investigation of the safety management efficiency in a coal mine aims to improve its safety management level thus ensuring coal mining safety. However, the safety management efficiency is affected by many factors especially for those coal mines operated underground. Furthermore, the constraint factors that are difficult to be identified and eliminated may impede safety

History of coal mining
The history of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today
