Development of aggregate resources for use in structural concrete has been encouraged in Japan to support infrastructure improvement and national land conservation. Natural aggregate is a valuable resource necessary for sound economic development, and its importance is growing. However, against the backdrop of the ongoing depletion of resources, growing concern over nature conservation and increasingly tightened control over resource use, the supply of natural aggregates such as sea/river/pit sand and sea/river gravel has been decreasing. Under the circumstances, it is necessary to conduct simulations of aggregate resources development technology such as the microtremor survey, the slope stability, and improvement of afforestation from a long-term standpoint in an effort to optimize and enhance the efficiency of the entire production system in the light of the project scale, the quality specifications required by customers and the development processes.
Furthermore, because contribution to development of a low carbon society will be required in the future, production plants and working faces need to be designed to enhance efficiency and CO2 reductions.
