Geological Hazard Tendency Analysis of Room and Pillar Mining Method Based on Energy Index

Abstract:

Geological hazards especially for the dynamic disasters are proven to be the most difficult problems encountered in the deep underground projects. This paper attempts to deal with the geological problem faced by Shizhuyuan multi-ploy metallic mine base on the results of mechanics tests and numerical simulation. In order to understand the mechanism dynamic disasters, a new energy index, the Local Energy Release Rate (LERR), is put forward in the simulating process. By tracking the peak and valley values of elastic strain energy intensity before and after brittle failure, the LERR is set as an index to ascertain the scope of the high dangerous region. The results showed that LERR can satisfactorily predict the dangerous region, and it will be more accurate with some necessary monitoring method. The study indicates the potential of LERR for evaluating geological hazards in deep underground excavations.
