“…Consequently, the contour lines of maximum inclination, maximum curvature and maximum horizontal deformation can be given, which makes the analysis of mining damage easier. Considering the reasonable length of the article, there is no detailed study on the expected parameters, and the relevant parameters in the reference [53] are selected when the prediction model is applied, as follows:…”

The traditional backfill mining method is a technology developed by the general trend of green coal mining, but with a high cost and an impact on production efficiency. This paper proposes a structured backfill mining method with high-water materials and pillars. The evolution of roof pressure appearance is assessed through the sensor and monitoring system in the hydraulic support. The main roof fracture step distance is determined based on the roof structure characteristics of backfill mining, and the backfill step distance of underground structural backfill is 22.7 m considering the safety factor. Through the simulation results of Abaqus commercial simulation software, the roof subsidence evolution of different backfill schemes under temporary load and permanent load is compared, and the rationality of the backfill step distance is verified. Based on the probability integral method, the surface subsidence prediction model is proposed, then the final value and the maximum dynamic change value of the surface subsidence at the north and south ends of the interchange bridge by traditional mining and backfill mining are analyzed, which verifies the rationality of the structural backfill mining method.

“…Consideration should be given to the joint impact of both effects of mining stated above, namely deformations and shocks [35], which increase the likelihood of building damage. A broad spectrum of impacts that coal mining had on buildings was presented in the works: [8,25,29]. in many cases, the deposits of useful minerals lie beneath highly urbanised areas.…”

Assessment of dAmAge cAuses of monumentAl objects locAted in mining AreAs -cAse studyThe paper presents an example illustrating the problems of assessing the causes of damage that occurred to building structures located in mining and post-mining area. it is frequently necessary to determine whether probable damages came from other, non-mining causes or were caused by underground mining. This issue is particularly significant when it comes to monumental, historical objects because the cost of repairs is typically very high. The purpose of this work is to demonstrate, using the magnificent church as an example, that damage to building objects situated in mining areas does not necessarily result from mining activities. As a result, every such situation should be thoroughly evaluated to determine whether such a relationship exists. For the assessment of such a conclusion, multidirectional studies in the framework of this work were carried out: hydrogeological, mining and technical factors that cause the damage to the church building in question were analysed.

“…Liu, X. [13], Trzałkowski, P. [14], López Gayarre, F. [15] and Can et al [16] analyzed the building failure mechanism through observing the building deformation and damage distribution in coal mining subsidence areas, in combination with numerical simulations and other measures, and then concluded the law on the influence from different displacement indexes upon the structural stability of buildings. According to the analysis by Cui [17] on building damage judgment methods, building classification and computer-aided analysis can facilitate in improving the accuracy of coal-mining-induced damage assessment.…”

This paper aims to evaluate the severities and causes of ground surface building and cropland damages after coal mining in a better way, and to clarify the correlation between the damage assessment indexes that influence mining. Against the backdrop of multi-seam mining in certain coal mines in China, the estimated results of each displacement and deformation were analyzed using GIS technology. The damage range determined for each deformation index is divided according to the displacement and deformation combined with the virtue of damage judgment threshold. The damage ranges on the ground surface based on the comprehensive value of each displacement and deformation index were obtained through superimposing those ranges delineated by each displacement and deformation index, and the law on influence from displacement indexes upon various levels of damage was analyzed in a quantitative manner accordingly. The results showed that coal mining destroyed 14 buildings and a cropland area of 11.96 hm2; among them, building damage was only associated with displacement indexes E (horizontal deformation) and T (inclined deformation). Seven buildings were solely destroyed by T alone; five buildings were solely damaged by E; two buildings were damaged jointly by E and T; and, moreover, with the aggravation in building damage level, the proportion of building damage due to E decreased while the proportion of building damage under the same level due to T increased. Regarding cropland destruction, the damage due to T accounted for 33.48% while the damage jointly caused by W (Subsidence), E and T accounted for 30.45%. Moreover, the proportion of damaged cropland area due to inclined deformation T was positively correlated with cropland damage level. These findings can provide a reference for rational judgment regarding civilian building and cropland destruction on the ground surface after coal mining.
