| Outline of Final Research Achievements |
This study, as part of the prevention of global warming, has established LCA (Life Cycle Assessment) approaches to reduce emissions of CO2(carbon dioxide), a greenhouse gas that occurs in association with the open-pit mining and aggregate production. Thus, it was intended to contribute to a low-carbon society. It is necessary to shift to environment-friendly open-pit mining method to continue the "sustainable development" in the mining and production of limestone and crushed stone. Labor-saving and low environmental load type open pit mining system of utilizing the latest IT (information technology) was constructed with the aim to respond to labor shortages caused by the arrival of population decline society.
