Multiplication Analysis of the Cause, Form and Extent of Damage to Buildings in Areas with Mining Impact

Abstract

This publication is a summary of all tasks carried out in recent years of research, calculations, simulations and analyse related to the performed research on parameter analysis that affect the form, scope and cost of removing damage in buildings and structures in areas with mining impact. The analysed problem is interdisciplinary and contains legal, geotechnical, engineering - mining, construction, material and economic analysis. The ground reaction forces were analysed for buildings and structures in the mining area. Coordinating activities of the land model, foundations and construction of buildings and structures in the mining area were adopted and the distribution rights and changes in additional reaction forces of the structure in the mining area were analysed and various factors which affect the construction damage were indicated. Problems were also identified in the mining impact forecasts that affect the design scope of new engineering structures and the impact of existing buildings and structures. The influence of various factors was analysed and additional dependency formulas were proposed, which are needed for current calculations and analyses of the scope and costs of strengthening the structure or its modernization. Based on the output data and the analysis of the results of the empirical examination of selected buildings, the determination of all factors affecting the technical condition of the building erected in the areas with the impact of mining operations. Classification according to currently used guidelines and clarification of new attributes affecting the technical condition of buildings and structures (typical and modern geometry of the building’s structure, type of foundation, type of construction protection, type and stiffness of the structure). Backward analysis of damages (their temporary changes) identified as factor affecting the current state of engineering objects.

FBG Strain Monitoring of a Road Structure Reinforced with a Geosynthetic Mattress in Cases of Subsoil Deformation in Mining Activity Areas

“…The nature of damage to the road infrastructure in mining areas and of the mobilization of limit states of load capacity is of a completely different origin compared to other areas [ 1 , 4 , 22 , 23 , 24 ] and is the effect mainly of the susceptibility of earthen structures and surfaces to horizontal unit strain with a loosening character (ε (mm/m)). This problem is illustrated comprehensively in the diagram in Table 1 and Figure 1 , Figure 2 and Figure 3 .…”

“…The ever-growing demand for new linear investments usually involves improvement to land with difficult geotechnical conditions. Such land is often described as low-bearing soils, including the herein analysed soils in areas affected by mining impacts [ 1 , 2 ]. The basic mechanisms determining the engineering methods of computational analysis of subsidence are connected with phenomena such as compaction, consolidation, changes in water conditions, or disturbances to the balance of soil massif.…”

FBG Monitoring of a Communication Paths and Roadways with a Geosynthetic Systems on Mining Heaps

“…In such analyses, the residual method is a frequent tool. It is used for known impacts of mining activity [11,12], in the area under investigation and for a specific construction design involving structural reinforcement or protection of the structures discussed in [14]. Subsequent estimates show that the selection of an appropriate material is one of the key attributes in the calculation of the investment costs for the assumed service life of the structure and for its assumed reliability.…”

“…The complexity of issues related to the effect of mining deformation on road structures requires a comprehensive approach to the assessment of the state of cooperation between the mining heap surface and the traffic project, along with appropriate protection against the anticipated adverse and abnormal impacts. Innovative conceptual and design works using modern state-of-the-art materials, including geosynthetics, with already-tested engineering properties are now a frequent subject of analysis and research of university projects in the Department of Civil Engineering [11,12,13,14]. The complex geotechnical conditions needed to strengthen and stabilize the subsoil of mining heaps using geosynthetic reinforcement are still an unexplored issue, so the monitoring of completed pilot rehabilitation projects for the land development concept is a key complement to the task.…”
