| Abstract: |
| By means of analysis on rock mass structure in openings with roof fall frequently-occuring area in Tangziao Section of Malage Tin Mine,11 unstable blocks selected from 239 structural blocks were spec1ally monitored, avoiding personal accidents and ensuring production safety. The research method introduced in this paper provides an effective way for prediction of roof fall or rib fall of some individual unstable rocks. |
