Abstract:

Studies of leaching of vitrified simulated high-level radioactive waste (HLW) evidence that most of actinides or their simulators enter leaching water in a colloidal form. In this paper, we consider a mechanism of colloid-facilitated migration of radionuclides from an underground repository of HLW located at a depth of a few hundreds of meters in fractured crystalline rocks. The comparison between data of field and laboratory measurements showed that the bulk permeability of the rock massif in field tests is much greater than the permeability of rock samples in laboratory experiments due to an

Abstract:

The paper analyzes the structure of coal beds. It is noted that coal beds belong to laminar massifs with characteristic oriented structure and pronounced anisotropy of strength properties, and include rock layers and consolidated hard inclusions. The quality criteria of the coal loosening process are highlighted. A selective method of separating coal from a massif by cutting along weakened surfaces is proposed as an alternative to the existing combine technology with continuous cutting of a massif from the surface.

Purpose. To develop a method for predicting fractured zones in a massif of sedimentary rocks formed due to the folding, by determining relative linear deformations that exceed those critical ones for discontinuity of rock massif. Methodology. The task of identifying fractured zones is to determine areas in the rock massif where tensile deformations, under the action of tectonic processes, have exceeded the critical limit. The determination requires the map construction of the researched area with the help of trend analysis and a series of mathematical calculations, namely, finding the distance

The issues of forecasting and preventing dynamic phenomena in coal mines, despite decades of research, remain insufficiently studied. The nature of dynamic phenomena is far from being known, and as the depth of mining of coal seams increases, the phenomena become more and more formidable and, as a rule, unpredictable.Most of the dynamic phenomena are related to the stress state of the massif and the peculiarity of its gas saturation, which is partly explained by the state of sedimentary rocks.

Abstract In this article, a problem of determining rock fracturing in layered anisotropic massifs is considered.

The study of fissure waters of crystalline rocks in the context of global warming to address issues of drinking water supply is highly relevant today. It has potential practical importance for the future.The sustainable use of groundwater in fractured rock aquifers requires a detailed knowledge of their hydraulic properties.

Abstract:

When carrying out mining operations, a rock massif responds to technological impacts in the form of developing strains and fractures. Under certain conditions, this response occurs as dynamic and gas dynamic destructions of rocks with intensive release of energy, which creates threats to security and disrupts a working technology. To substantiate the optimal mining technology, which would be maximum adequate to the specific geological and geomechanical conditions of a deposit development, it is necessary to organize a comprehensive monitoring of geomechanical processes in rock massifs.

Abstract:

In the construction of essential structures for the determination of the mechanical properties of large-scale heterogeneous fractured rock soils, people usually rely on the results of more representative large-scale field testing when assigning expected performances. Such large-scale field testing is conducted with the help of concrete stamps or rock pillars, usually with a square in plan outsole, for compression and flat shear, in galleries or in open sites. However, there are drawbacks: the complexity in the implementation and interpretation of the testing data, low informativeness, etc. Due

For an engineering geologist, covered karst areas are of special interest, not only because these are the most widespread on the Earth.

Abstract:

For hard rock massifs, structural disturbance is a key indicator of mining structure stability. The presence of intersecting structural elements in the massif reduces rock strength and leads to formation of potential collapse structures. In addition to that, disjunctive deformations that penetrate rock strata serve as channels for fluid migration and connect aquifers into a single system. It was established that the largest of them –faults of east-northeastern, northeastern and northwestern directions – form the kimberlite-bearing junction of the Udachnaya pipe. These faults represent zones of

Therefore, conceptual models for deep geothermal applications were developed for different field sites regarding different local conditions. In Bavaria, Germany, geothermal applications were successfully carried out in carbonate horizons at depths of 4000 to 6000 m. Matrix permeability and thermal conductivity was mainly studied in karstified carbonates from the Late Jurassic reef facies. Similar to Bavaria, carbonates

Abstract:

Soil massif fracturing has a significant impact on change in engineering and geological conditions and, as a result, on stability of structures. Development of tectonic fracturing of local structures, taking into account the history of the process, its mechanism, resulting stresses in the massif and subsequent deformations of the rocks, led to a change in their structure, composition and strength characteristics, activation of hypergenesis and exogenous processes. The above circumstances require careful attention to identification of areas of increased fracturing, as the most dangerous in term
