This article presents the findings of experimental investigations conducted to assess the influence of alternating temperature variations on the energy consumption associated with the destruction of dolomite samples from the Internatsionalnaya pipe and limestone samples from the Mokhsogolloh quarry. The evaluations were carried out under nival conditions, involving exposure to varying concentrations of sodium chloride (NaCl) solutions, with salt concentrations ranging from 0% to 20%. The findings reveal that after five freeze-thaw cycles in a nival environment, the energy required for the destruction of dolomite from the Internatsionalnaya pipe decreased by 6% in the absence of salt (0% concentration). However, as the concentration of salt in the solution increased, the energy necessary for the destruction of the dolomite samples escalated to levels comparable to those recorded prior to the freeze-thaw cycles. In contrast, the energy required for the degradation of limestone samples from the Mokhsogolloh quarry decreased by a maximum of 15% after five freeze-thaw cycles, regardless of the salt concentration present in the solution. Thus, unlike the dolomite from the Internatsionalnaya pipe, the influence of salt concentration on the energy intensity of limestone destruction from the Mokhsogolloh quarry was not observed. Furthermore, it was concluded that nival weathering conditions have a lesser effect on the examined rock samples compared to aquatic conditions.

The investigation into the influence of water on the mechanical properties of rocks is essential for their effective application in various fields, particularly in mining, dam construction, tunneling, and waste management. The presence of water within the pore spaces of geological materials, along with the existence of pores, cracks, and voids, plays a significant role in determining their mechanical characteristics. This study presents the results of an experimental investigation into the effects of water saturation conditions on the compressive strength of dolomite and limestone specimens, which are recognized as host rocks in the diamond deposits found in the Botuobinskaya and Dalnaya tubes. Following established research methodologies, specific water saturation regimes were selected, and mechanical tests were conducted on specimens that were saturated to predetermined levels and subsequently maintained for varying durations. The results from the three series of tests revealed the dependence of the compressive strength of dolomite on the duration of holding time. A significant effect of holding time on the material’s strength was observed, indicating that it can lead to both a decrease and an increase in strength. This phenomenon is hypothesized to be associated with a non-homogeneous distribution of water and the development of a “dry” core within the specimen. The analysis indicates that, within the framework of the “dry” core model, various fracture scenarios may develop within the material. These scenarios will affect the nature of the dependence of the specimen’s strength on holding time in a wet condition, including its non-monotonic behavior. The findings are not only fundamentally important for advancing the understanding and accurate description of the mechanisms of water interaction with rock but also have practical implications for assessing the stability and long-term durability of flooded mine workings.

Subpermafrost aquifers are distinguished by their low stratum temperatures and pressures that approximate conventional hydrostatic pressures, rendering them suitable geological formations for the organization of underground gas storage facilities in a hydrate state. The design of such facilities requires the execution of experimental studies focused on hydrate formation within porous media. This paper examines the subpermafrost aquifers located in the Vilyui syneclise, where the hydrate stability zone covers Cretaceous and Jurassic deposits, specifically terrigenous-clayey strata. The mineralogical and granulometric composition, density, porosity, and moisture content, along with the presence of clays in the porous medium, influence the conditions conducive to hydrate formation. Therefore, the investigation of hydrate formation in clayey soils is a critical component that will support the development of underground gas storage facilities. To analyze the thermobaric conditions associated with hydrate formation, the method of differential thermal analysis was employed. The samples of porous media comprised clayey soils with varying moisture content, ranging from 15% to 40%. The results indicate that in soils with a moisture content of 20% or greater, a mechanical mixture of hydrates consisting of nearly pure methane and gases with higher molecular weights is produced. Additionally, it was observed that an increase in the moisture content of clay soils correlates with a decrease in the kinetic characteristics of hydrate formation. Based on the conducted research, it can be concluded that porous media characterized by clay layers with minimal moisture content are optimal for the establishment of underground gas storage facilities in a hydrated state

The instability of an open wellbore during directional and horizontal drilling is a critical issue that can lead to emergencies and significant economic losses. One of the key methods to prevent wellbore collapse is the careful selection of drilling fluid density based on geomechanical modeling. The objective of this study is a comparative analysis of the influence of the most commonly used failure criteria (Coulomb-Mohr, Drucker-Prager, Hoek-Brown, Mohr-Coulomb, and Lade) on the calculation of drilling fluid density required to ensure wellbore stability. The work involves one-dimensional geomechanical modeling using the RN-SIGMA 2.0 software package with logging data (density, interval transit times of longitudinal and transverse waves) from five wells obtained from open sources. We calculated profiles of geostatic and pore pressures, dynamic and static elastic properties (Young’s modulus and Poisson’s ratio), strength properties (uniaxial compressive and tensile strength limits, internal friction angle), as well as horizontal stresses according to a poroelastic model. The results showed that the choice of failure criterion significantly affects the required drilling fluid density to prevent wellbore collapse. The lowest density values were obtained using the Lade criterion, while the highest values corresponded to the Hoek-Brown and Drucker-Prager criteria. The classical linear Coulomb-Mohr criterion yielded intermediate density values. These differences are due to different mathematical formulations of the criteria and their consideration of various rock failure mechanisms. The findings indicate the necessity of carefully selecting a failure criterion appropriate for the lithology and mechanical properties of specific rock intervals.

This article examines the history of kayurs-reindeer sled drivers and geological expedition guides-from Sadynsky nasleg of the Mirny District in Yakutia, revealing their central but unrecognized role in Soviet diamond exploration from the late 1940s through the 1960s. In the harsh conditions of Western Yakutia, geological expeditions heavily depended on reindeer sleds and the specialized knowledge of local Evenk communities for navigation, survival, and access to remote territories. Drawing on archival documents, participant memoirs, and oral histories collected in the nasleg, this study reconstructs the working conditions, payment systems, and institutional relationships that governed kayurs' labour. The analysis demonstrates that indigenous workers were not merely auxiliary to Soviet industrial expansion but constituted its operational foundation during the critical early phase of diamond discovery. The article further exposes the systematic exclusion of kayurs from labour protections and state benefits accorded to other expedition members, revealing how Soviet industrial policy simultaneously depended upon and marginalized indigenous expertise. Rather than describing this relationship as ‘participation', the evidence shows that kayurs constituted the irreplaceable force upon which Yakutia's industrial transformation was built.
