A STUDY OF STABILITY ANALYSIS FOR UNDERGROUND EXCAVATION USING KEYBLOCK THEORY AND COMPUTER SYSTEM. LARGE ROCK CAVERNS - PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM, HELSINKI, FINLAND, 25-28 AUGUST 1986. VOLUME 2

One of the significant problems occurring at the excavation of hard or the middle-hard rock mass is thought to be structural failure caused by falling or sliding of blocks defined with intersecting structural discontinuities. It is thought that the keyblock theory using a computer system is very effective to deal with such a three dimensional problem. With the present method, the existence of keyblocks prior to the excavation can be easily forecast. This paper shows the methods of developing such a computer system. For the covering abstract of the symposium see IRRD 810647. (TRRL)
