Estimation of coal seams gas content for evaluating potential use of methane drainage system in Tabas coal mine

M. Mohtasham Seyfi; J. Khademi Hamidi; M. Monjezi; A. Hosseini

Volume 9, Issue 3 , July 2018, , Pages 667-677

http://dx.doi.org/10.22044/jme.2018.6783.1501

Abstract
  Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' ...  Read More
