Opis:
The scientific objective of this issue is to estimate the number and the significance of variables defined for particular functions, describing the nature, scope and type of impacts on buildings located in mining areas in terms of the technical condition of civil structures and costs of their possible protection and repair or modernisation. This publication analyses a problem of risk response as separate stages of a risk management process in investment projects being carried out in construction industry in the areas with mining impact. Specified and diagnosed variables are analysed in a selected respect, with particular emphasis on the assessment of the ultimate limit state and serviceability limit state of the tested civil structures. The prognostic knowledge of the process of protecting or repairing buildings on an active subsoil, within the assumed time range of the design use of the civil structures and the predicted mining impacts, is essential in an analysis of the form and scope of responses of the structures to adverse impacts and when estimating the cost of building interaction with the subsoil through the entire life cycle of the structure. The subject matter is interdisciplinary, covering both subjects in the field of engineering, as well as stochastic processes, econometrics and reliability of output data predicting the operational impact of mines in analysed urban areas.

Opis:
In this article, the issue of mining impact on road pavements and subgrade is presented, taking into account the interaction between geosynthetic reinforcement and unbound aggregate layers. Underground mining extraction causes continuous and discontinuous deformations of the pavement subgrade. Structural deformations in the form of ruts are associated with the compaction of granular layers under cyclic loading induced by heavy vehicles. Horizontal tensile strains cause the loosening of the subgrade and base layers. The granular layers under cyclic loading are additionally compacted and the depth of ruts increases. Moreover, tensile strains can cause discontinuous deformations that affect the pavement in the form of cracks and crevices. Discontinuous deformations also affect the pavement in the fault zones during the impact of mining extraction. The use of geosynthetic reinforcement enables the mitigation of the adverse effects of horizontal tensile strains. Horizontal compressive strains can cause surface wrinkling and bumps. Subsidence causes significant changes in the longitudinal and transverse inclination of road surface. Both examples of the laboratory test results of the impact of subgrade horizontal strains on reinforced aggregate layers and the selected example of the impact of mining deformation on road subgrade are presented in this article. The examples show the beneficial impact of the use of geosynthetic reinforcement to stabilize unbound aggregate layers in mining areas.
