Table 1: Cont. Based on this, many researchers [14; 15; 16; 17; 18] believe that studies on the spatial and temporal distribution patterns of accident sites, such as open pits, dumps, and tailings ponds where geological hazards occur, can help determine their intrinsic correlation with natural factors such as climate and topography. Increasingly, research institutions are recognizing the geohazard risks posed by mines and are attempting to assess the distribution of mine sites and mine spoil disposal volumes on a national scale. In South Africa, it is estimated that 1100 mines produce 72.3% of the country's total mine spoil while occupying 25 km\({}^{2}\) of land for tailings pond construction [19]. In Australia, more than 80,000 abandoned mines are recorded, posing a considerable threat to the surrounding area [20], in addition to more than 1750 tonnes of mine spoil from operating mines each year [21].
