Abstract
The environmental impacts of coal extraction and production are very high and vary depending on the methods used in underground mining. The thermal coal extraction scenarios in the municipality of Paipa, Boyacá were determined and the environmental aspects involved were evaluated through the application of the SimaPro 8.5.0 ® software, stratified by resources, materials and quantity of coal to be exploited in three mines chosen for the Life Cycle Impact Assessment (LCIA), based on the NTC-ISO-14040 for each of the extractive methods identified in the municipality with the Eco-indicator tool 99-H-V2.06/Europe-EI-99-HE-HAS®. It was determined that the manual starting method is less polluting for all damage categories, depending on materials and tools used in the mine, it is also the second most productive when analyzing the life cycle (LC) for monthly production. The mechanized method with electric hammer, reported greater impact on all damage categories both, when evaluated in the LC by monthly production, being the mine that uses this method the one that generates more coal, and when analyzing the LC that involves the amount of materials and resources used. The semi-mechanized start up (combination of electric hammer and pick-shovel) is the one that has less impact when analyzing the monthly production and the second to impact when analyzing the technique used for the start-up. Of all the categories of damage the most impacted is human health, associated with occupational exposure in the development of this work.
