“…However, inclinometers could both determine the sliding surface, and track the subsurface movement rates within the landslide, as done effectively elsewhere (Borgatti et al, 2006;Macfarlane, 2009;Jiao et al, 2013;Massey et al, 2013). As shown in Figure 4 and Figure 5, the inclinometer tubes were installed in three boreholes (B04, B05 and B06) by DHT drilling, and 20 surface monitoring points were distributed on the slope.…”

“…Their characteristics are crescentic-shaped headscarps, gentle multi-terraces and steeply sloping toes that stretch into rivers (Wang et al 2003;He 2005;Dong et al 2014). Topographically, the 1500 m long and 4000 m wide DAL shows similar characteristics as these ancient landslides, being steep at the upper part and the foot, and having gentle step-like terraces in the middle part ( Figure 2 and Figure 3) (Jones 1993;Dewitte et al 2006;Panek et al 2009;Jiao et al 2013). …”

“…In areas prone to instability, such as in the case described in this paper, the induced stress state can trigger or accelerate landslide movements, even on large scale (Sciotti and Calabresi, 2000;Picarelli et al, 2002;Barla et al, 2006;Noferini et al, 2007;Urcioli and Picarelli, 2008;Wang, 2010;Bozzano et al, 2011;Jiao et al, 2013;Sciotti and Pigorini, 2013;Maiorano et al, 2014). In particular, Urcioli and Picarelli (2008) reviewed some Italian case studies of the interaction between landslides and man-made works.…”

“…In particular, large amounts of sediment and debris can flow into nearby streams due to heavy rainfall during the monsoon season. The substantial modification in physicochemical properties related to mine activities has been investigated intensively by many researchers (Meju 2000;Ferreira da Silva et al 2009;Jiao et al 2013;Neiva et al 2014), especially with regard to heavy metal pollution, stream sedimentation, and ground subsidence during mining work; however, few studies have investigated miningrelated landslides. Recently, one of the largest known debris flows occurred at the Bingham Canyon open-pit copper mine, also known as the Kennecott Copper Mine, near Salt Lake City, Utah, USA (Pankow et al 2014).…”

Geotechnical and rheological characteristics of waste rock deposits influencing potential debris flow occurrence at the abandoned Imgi Mine, Korea

Mass movements associated with abandoned mines are dangerous and destructive. Local communities near abandoned mine sites are often threatened by the effect of extreme precipitation events on these sites. In this study, the geotechnical and rheological characteristics of mine deposits were examined to delimit the hazardous areas near abandoned mines. Waste rock materials were collected from a pyrophyllite mine deposit in the mountainous region of Korea, and a sieve analysis was performed to determine the grain size distribution. The yield stress in the debris flow modeling was determined using fall cone and rheometric tests. Rheological tests were performed on materials finer than 4.75 mm using a ballmeasuring system rheometer. These samples were mainly composed of gravels and sands with small clay content. The waste materials typically exhibited a shear-thinning behavior within a given shear rate ranging between 10 -5 and 10 2 s -1 . The yield stresses obtained from the rheometric tests agreed well with those obtained from the fall cone tests. For the input parameter, we selected the yield stresses ranging from 100 to 500 Pa. As a case study, the debris flow mobility associated with the abandoned mine was examined using a one-dimensional flow dynamic model. The runout distance and velocity of the waste materials are strongly dependent on the yield stress; both factors significantly increase with decreasing yield stress. However, even under the highest yield stress (i.e., 500 Pa), the failed mass can flow into the mountain stream. Thus, the physico-chemical contaminations of areas downslope of abandoned mines may be unavoidable with respect to extreme rainfall events.
