| Outline of Final Research Achievements |
As to develop the low rank coal mining system with the low environmental impact, data about geological conditions of low rank coal seams, conventional-state of the art mining systems, etc were collected and the database for low rank coal was developed.
Appropriate mining system was proposed and the suitable mining design was investigated by field investigation and a series of numerical analysis. Moreover,the rehabilitation program at the mined out area were also discussed in terms of the suitable soil conditions and species of plants.
