Industrias Peñoles tookCoal mining World Coal Association,Longwall mining involves the full extraction of coal from a section of the seam, or ‘face’ using mechanical shearers. The coal ‘face’ can vary in length from 100350m. Selfadvancing, hydraulicallypowered supports Environmental impact of miningassociated carbon ,Carbon emission sources in opencast mines mainly included fuel and explosive use, coal mine methane escape, coal and gangue spontaneous combustion, and electricity consumption. The carbon emission of the PMA increased from 4 × 10 4 Mg in 1986 to 1.05 × 10 6 Mg in , with an average annual increase of 11.64%.
