Greenhouse gas emissions from shallow uncovered coal seams
International Journal of Mining Science and Technology, 2014 Abstract This study discusses a method of quantifying emissions from surface coal mining that has been trialled in Australia. The method is based on direct measurement of surface emissions from uncovered coal seams in mine pits, concurrent measurement of residual gas content of blasted coal in mine pits, and measurement of pre-mining gas content of ...

Stress Observation and Strata Behavior in Fully-mechanized Coal Face of Shallow Coal Seam
IOP Conference Series: Earth and Environmental Science, 2019 Abstract In order to solve the problem of the strong ore pressure in the mining process of a shallow buried coal seam working face, the ore pressure law of a shallow buried coal seam working face was observed. According to the observation results of ore pressure, the law and characteristics of ore pressure on the working face of shallow ...
