Mined-out limestone/aggregate quarries in Japan contain many high and enormous pit walls. Many precious resources are abandoned in these final pit walls. In addition, there are many mines which are located in or near populated areas in Japan. Utilisation of the potentially useful under- ground space at mined-out sites is a topic relevant to the practice of surface mining._x000D_
This paper describes and discusses the concept of underground space utilisation and tunnelling systems, referring specifically to geotechnical/ tunnelling parameters._x000D_
