Mine Waste as Resource: Indian Mining Scenario of Coal and Non Coal Mining Sector
The International Journal of Recent Technology and Engineering (IJRTE), 2021 Mother Nature has bestowed India with huge resources of coal, iron ore, bauxite, manganese and limestone. India has one of the lowest per capita availability of land due to population of more than 1.3 billion. The transformation from under developed to developed economy warrants enormous increase in mineral production.

Development and application of coal burst experiment system based on local mine stiffness theory
Meitan xuebao, 2023 The loading mine stiffness and the post-peak stiffness of a coal pillar are important factors affecting the occurrence of coal bursts. In order to systematically study the mechanism of coal bursts and pillar bursts based on local mine stiffness theory, a

Automatic Identification of Coal and Rock/Gangue Based on DenseNet and Gaussian Process [PDF]
arXiv, 2022 To improve the purity of coal and prevent damage to the coal mining machine, it is necessary to identify coal and rock in underground coal mines. At the same time, the mined coal needs to be purified to remove rock and gangue. These two procedures are manually operated by workers in most coal mines.

A high-resolution gridded inventory of coal mine methane emissions for India and Australia [PDF]
arXiv, 2021 Coal mines are globally an important source of methane and also one of the largest point sources of methane. We present a high-resolution 0.1deg x 0.1deg bottom-up gridded emission inventory for methane emissions from coal mines in India and Australia, which are among the top five coal-producing countries in 2018.

Enhanced Coalbed Methane Extraction by Geothermal Stimulation in Deep Coal Mines: An Appraisal [PDF]
arXiv, 2021 Coalbed methane embedded in coal seams, is an unconventional energy resource as well as a hazardous gas existing in mining industries, which attracts lots of global attention. As the largest coal producer, the mining industry in China had to deal with many hazards induced by methane for decades.

Methane Emissions from Super-emitting Coal Mines in Australia quantified using TROPOMI Satellite Observations [PDF]
arXiv, 2021 Two years of satellite observations were used to quantify methane emission from coal mines in Queensland, the largest coal-producing state in Australia. The six analyzed surface and underground coal mines are estimated to emit 570+/-98 Gg a-1 in 2018-2019.
