Assessment of the influencing factors on subsidence at abandoned coal mines in South Korea

A Novel Caving Model of Overburden Strata Movement Induced by Coal Mining

“…The subsidence factors mainly include the method and parameters of mining, width of the panel, thickness of the overburden, angle of the draw, dip of the coal seam, depth and thickness of the coal seam, geological and stratigraphic conditions, and so on [14,18]. Engineering practices show that the fully mechanized slice mining and multi-seam mining generally give rise to greater subsidence as a result of the larger extraction quantity and repeated mining disturbance.…”

“…Severe conflicts of interest are especially noteworthy regarding human life and the exploitation of energy resources [12][13][14][15][16][17][18][19][20][21][22][23][24]. Exploitation activities inevitably cause ground subsidence, water loss, building damage, and a series of other problems, especially in some eco-environmental fragile areas [3,[25][26][27][28][29][30][31][32][33][34][35].…”

Geomorphological and Hydrological Effects of Subsidence and Land use Change in Industrial and Urban Areas

“…Subsidence basins worldwide share similar geomorphological and hydrological effects and a similar sequence of transformation in land use, which typically leads from fully utilised to wasteland (Quanyuan et al ., ; Abdikan et al ., ). This is illustrated very well by cases from around the world (Drecker et al ., ; Johnson, ; Martinec & Schejbalova, ; Michalczyk et al ., ; Mancini et al ., ; Quanyuan et al ., ; Harnischmacher, ; Djamaluddin, 2011; Deliormanli, ; Fan et al ., ; Lee et al ., ; Marschalko et al ., , , ; Pacheco‐Martínez et al ., ; Wójcik, ; Cheng et al ., ; Loupasakis et al ., ; Xu et al ., ), including from elsewhere within the Silesian Upland (Jankowski et al ., ; Dulias, , ; Machowski et al ., ; Rzetala, ; Machowski & Rzetala, ).…”

“…Comparable values were also found farther east, in South Korea. After analysing nearly 550 cases of land subsidence related to coal mining nationwide, it was found that the average depth of basins and hollows there was 3.9 m (Lee et al, 2013). Subsurface mining of other minerals may also lead to substantial subsidence.…”

“…Within subsidence basins, the surface hydrographic network is altered, and the factors conditioning the occurrence of groundwater change (Xiao et al, 2014); this is accompanied by shifts in the chemical composition of waters that result in changes in biological communities (Yi et al, 2014). A review of published research suggests that water bodies, the most striking environmental effects of subsidence, tend to be rare in these types of hollows (Drecker et al, 1995;Johnson, 2004;Martinec & Schejbalova, 2004;Mancini et al, 2009;Quanyuan et al, 2009;Harnischmacher, 2010;Djamaluddin, 2011;Deliormanli, 2012;Fan et al, 2012;Lee et al, 2013;Marschalko et al, 2013Marschalko et al, , 2014aMarschalko et al, , 2014bPacheco-Martínez et al, 2013;Cheng et al, 2014;Xu et al, 2014). They were and remain quite common in the UKfor example, Big Waters Northumberland Wildlife Trust Reserve and mining flashes in Lancashirefor example, near Wigan.…”
