“…In the environmental thematic group can be defined the second approach, where the environmental impact on mining operation performance was investigated. In this area, research works were focused on seismic risk assessment (e.g., [109,110]) and water risk assessment (water inrush problems [111][112][113], water resources in mining [114], and surface water contamination [115]).…”

Recently, there has been a growing interest in the mining industry in issues related to risk assessment and management, which is confirmed by a significant number of publications and reports devoted to these problems. However, theoretical and application studies have indicated that risk in mining should be analyzed not only in the human factor aspect, but also in strategic (environmental impact) and operational ones. However, there is a lack of research on systematic literature reviews and surveys of studies that would focus on these identified risk aspects simultaneously. Therefore, the purpose of this article is to develop a literature review in the area of analysis, assessment and risk management in the mining sector, published in the last decade and based on the concept of a human engineering system. Following this, a systematic search was performed with the use of Primo multi-search tool following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The main inclusion criteria were: (a) not older than 10 years, (b) article written in English, (c) publication type (scientific article, book, book chapter), (d) published in chosen electronic collections (Springer, Taylor and Francis, Elsevier, Science Direct, JSTOR). This resulted in the selection of the 94 most relevant papers in the area. First, the general bibliometric analysis was conducted. Later, the selected papers in this review were categorized into four groups and the critical review was developed. One of the main advantages of this study is that the results are obtained from different scientific sources/databases thanks to using a multi-search tool. Moreover, the authors identified the main research gaps in the area of the implementation of risk management in the mining industry.

“…For example, the AHP-type vulnerability index method was used to partition and evaluate the risk of water inrush No. 11 coal seam floor from underlying confined aquifer in the Hancheng Coal Mine and the assessment results had high accuracy (Dai et al 2018). An optimized AHP-type vulnerability index method was used to partition and evaluate the risk of water inrush of the No.…”

This study predicts the risk of water inrush from the Ordovician limestone aquifer to No. 17 coal seam in the Yangcun Coal Mine that is mining above confined aquifer. Analysis of geological and hydrogeological data, the analytic hierarchical process modelling of a vulnerability index (VI), water inrush coefficient method, and the safety factor under pressure method were used to systematically assess the risk of water inrush. Firstly, the main influencing factors were determined, including the yield and pressure of water in the Ordovician limestone aquifer, the effective thickness of water-resisting strata, the ratio of limestone to sandstone-mudstone in these strata, the fault fractal dimension, and the fault scale index. A vulnerability assessment model was established and VI values were calculated. Water inrush risk partitioning thresholds were obtained by the natural breakpoint classification method. Secondly, based on the field water injection test of the study area and its surrounding mining areas, the water-resisting strength of the rock layer from No. 17 coal seam floor to the roof of Ordovician limestone is obtained. Finally, to verify the accuracy of the model, water inrush coefficient and safety factor under pressure were calculated. The results can well verify the accuracy of the analytic hierarchical process (AHP) vulnerability index assessment results. These study results provide guidance for predicting water inrush disasters related to the mining above confined aquifer of deep coal seam.

“…Based on the above reasons, from the beginning of the 20th century to the present, some scholars have adopted the geographic information systems (GIS) with linear or nonlinear integration technology and proposed the water inrush evaluation method based on multisource information fusion technology. For example, Dai et al analyzed the water inrush risk of the 11th coal seam in Hancheng mining area using GIS and analytic hierarchy process (AHP) [13]. Wu et al proposed a karst water inrush water risk prediction method based on GIS and artificial neural network (ANN) coupling technology [14].…”

The use of multisource information fusion technology to predict the risk of water inrush from coal floor is a research hotspot in recent years, but the current evaluation method is mainly based on a constant weight evaluation model. Using constant weights to reflect the control effect of changing factor state values on water inrush evaluation has obvious limitations, and it is unable to describe the control effect of the hydrogeological condition mutation on the water inrush from the floor. In order to solve the above problems, this manuscript introduces the idea of variable weight into the field of water inrush evaluation, expounds on the significance of variable weight theory for water inrush evaluation, analyzes the characteristics of mine water inrush variable weight evaluation, and, on this basis, further combines GIS-based multisource information fusion technology and typical engineering case to compare with the evaluation effect map, evaluation unit, and comprehensive evaluation values. The differences between the variable weight model (VWM) and the constant weight model (CWM) are analyzed, which proves that the evaluation process of the variable weight evaluation model is more reasonable and can effectively improve the evaluation accuracy.
