Block Collapse Risk Management

The territory of Kyrgyzstan belongs to the tectonically active region. A characteristic feature of the rock massif is a block structure. The exploited gold ore deposits of Kyrgyzstan are upland, located in the zone of influence of discontinuous tectonic disturbances. In recent years, unplanned rockfalls have become more frequent at mining enterprises in Kyrgyzstan. Until now, due attention has not been paid to ensuring the safety of mining operations at such deposits. The stability assessment for such arrays is carried out according to existing methods acceptable for isotropic media. A block array is not. A distinctive feature of upland mineral deposits is that the sizes of the blocks in the weathering zone have different parameters and insignificant adhesion, and the blocks are kept in equilibrium only due to the action of gravity.
