Calculation method of greenhouse gas emission in open pit coal mines.

Based on the comprehensive analysis of the greenhouse gas emission constitution in open pit coal mine, the corresponding econometric model of carbon emission was established. The research indicates that the greenhouse gas sources of surface mine involves the indirect emission of power consumption, direct emission of fuel combustion and explosion, CH4spilling, the greenhouse gases spilling caused by spontaneous combustion of gangue and coal, reduction of carbon fixation caused by mining disturbance. Based on this finding, the calculation method of various carbon emission sources was given referring to IPCC Guidelines for National Greenhouse Gas Inventories, and the econometric model of carbon emission was established. Taking the case study of Buzhaoba Open Pit Coal Mine, calculating that emission of greenhouse gas in the open pit mine is 122 351.19 t in the year of 2008. [ABSTRACT FROM AUTHOR]
