The work is aimed at creating methodological provisions to substantiate the safe parameters of the thermal regime in permafrost rocks when constructing underground mine excavations in the Arctic region. An idea is to control the thermal regime by creating mathematical models, taking into account the main technological operations during excavations driving. The paper presents the results of experimental studies and evaluates the thermal impact of various technological processes during the construction of mine excav...

The aim of the work is to create methodological provisions to justify the safe parameters of the thermal regime in permafrost rocks during the construction of underground complexes of small power nuclear plants in the Arctic region. The idea of the study is to assess the thermal regime of long-span mining excavations using mathematical modeling methods. To ensure the stability of underground mine excavations at the construction stage in the permafrost, the authors verify the use of various heat-protective systems....
