The geophysical investigations are carried out at the Kangalass open pit coal mine using the round penetrating radar and electrical tomography. The main frost effects in rock mass and in water retaining dam are described. The investigation procedure is developed, and the wave fields are characterized. The GPR surveys aimed to reveal water invasion zones in a rock block to be blasted and to trace dynamics of a seasonal thawing layer are presented. The integrated analysis of GPR and electrotomography data is performed to determine adverse freeze-and-thaw processes at the dam bottom. Applicability of GPR in prediction of unfavorable freeze-and-thaw activities is demonstrated.

岩石的冰冻学分析以预测不利的冻融效应

地球物理调查是在康加拉斯露天煤矿使用圆形穿透雷达和电断层扫描进行的。描述了岩体和挡水坝中的主要霜冻效应。开发了调查程序，并对波场进行了表征。探地雷达勘测旨在揭示待爆破岩块中的水侵入区并追踪季节性融化层的动态。对探地雷达和电断层扫描数据进行综合分析，以确定坝底不利的冻融过程。证明了 GPR 在预测不利的冻融活动中的适用性。
