Abstract

The experimental version of a bidimensional measurement facility allows recording displacement of rock blocks in the normal direction relative to a fault and their shear displacement relative to one another. In 2020 the facility was deployed at Zarnitsa open pit diamond mine, and was included in the long-term geodynamics monitoring in the zone along a fault which cuts the open pit. It is found that displacements of rock blocks in the normal direction to the fault are periodic at the maximum amplitude of 3.5 mm, while the shear displacement is reversal at the maximum amplitude of 1 mm.

用于对深露天矿中的岩块位移进行双向测量的多通道设备

摘要

二维测量设备的实验版本允许记录岩块相对于断层的法向位移及其相对于彼此的剪切位移。2020 年，该设施部署在 Zarnitsa 露天钻石矿，并被纳入该地区沿切割露天矿的断层的长期地球动力学监测。发现岩块在断层法向的位移是周期性的，最大振幅为3.5 mm，而剪切位移在最大振幅为1 mm时是反向的。
