ABSTRACT
For the purpose of monitoring geodynamic behavior in surrounding rock mass of deep open pit mines, the Institute of Mining, SB RAS, has developed and manufactured an experimental prototype of a multichannel measurement system named Karier. The system is composed of measurement devices which use different types of sensors integrated in the common units of data reception, procession and transfer.
The Karier measurement system was deployed in the Zarnitsa open pit mine at diamond-bearing kimberlite pipe, Republic of Sakha (Yakutia), Russia. Zarnitsa pipe occurs at the intersection of quasi-perpendicular faults. The sensors of the Karier system were installed on the opposite pit walls at the fault edges.
The monitoring results show that the fault was widening on one pit wall and narrowing on the opposite wall. The positive trend in the change in the fault wide makes 0.4 μm. The fault shows high susceptibility to the blasting operations.
