“…In contrast, faults that form later have a better personality and connectivity between faults, lesser filling, poorer cementation on their surface, and higher water-bearing (conducting) capacity. Faults in different formation periods are produced under the action of structural stress in different directions, and thus, they have distinct occurrences (Fu et al, 2022a(Fu et al, , 2022b. In this study, the occurrence of all strata in the study area was recorded and counted; the fault rose map of the study area was made (Figure 2), and the age of formation of the fault was estimated and divided (Table 1).…”

Mine water disaster is closely related to the geological structure of the mine. A scientific evaluation of the complexity of the minefield structure can greatly contribute to mining safety. In this study, we optimized the fault impact index in the study area and proposed an improved local linear embedding (LLE) algorithm by investigating the Shengquan coal mine. We analyzed the fault formation age and connectivity between faults in the study area, combined with topology theory, and based on previous studies. The mechanical properties of faults and the influence of small faults on the strata can be combined to derive a quantitative evaluation model of the structural complexity of mines. Based on the evaluation model, the study area was divided into a simple structural area, a medium structural area, and a complex structural area. By comparing the location of water inrush points in recent years with the three-dimensional high-density electrical exploration of the 21,304 working face, the effectiveness and rationality of structural complexity zoning were determined.

“…The complexity of fault structures can reflect the extent to which a region is cut and destroyed by faults (Zhou, 2013). Therefore, evaluating the complexity of fault structures (Fu et al, 2022a(Fu et al, , 2022b can contribute to guiding mine safety production (Singh, 1986).…”
