Development of Australia Specific PM10 Emission Factors
Emission factors for specific mining activities were determined. In addition, bulk samples of the relevant source materials ( e.g. haul road dust, coal stockpiles) were collected at the time of the PM 10 measurements, and the materials were subsequently analysed for silt content, moisture content, and threshold friction velocity.
GREEEN HOUSE GAS EMISSIONS FOR COAL MINE
Content of coal bed methane is assessed by several factors, amongst which the rank of the coal is the most important for CH4 emission. As the Singrauli coal is low rank at lower depth of less than 300 m, methane gas is generated during opencast mining operation. The Central
Overview of Greenhouse Gases Greenhouse Gas (GHG
Carbon dioxide (CO 2) is the primary greenhouse gas emitted through human activities.In 2016, CO 2 accounted for about 81.6% of all U.S. greenhouse gas emissions from human activities. Carbon dioxide is naturally present in the atmosphere as part of the Earth's carbon cycle (the natural circulation of carbon among the atmosphere, oceans, soil, plants, and animals).

Emission Factors 1 Ning
USEPA follows an emission factor quality rating (EFR) scheme for the emission factors given in AP42. These depend upon the number of sites, numbers of tests and test data variability on which the emission factors were developed. The rating scale varies from A to E, with A denoting excellent or a high degree of certainty and E a
