• pillars during the extraction of adjacent panels. The subsidence process is expected to be <br />mature within 2 years after mining. <br />Subsidence characteristics for any coal field depends on site-specific geologic <br />conditions and mining practices, including strata competence, geologic structure, <br />topography, extraction height, extraction speed, and mine designs. For instance, rapid <br />changes in topographic conditions are known to influence both naturally occurring and <br />mining-induced rock mass wasting, including sandstone escarpment failure (Maleki and <br />others 2001) and landslides. The site-specific subsidence parameters for the Dove Gulch <br />area are addressed in the following sections using available monitoring results locally and <br />regionally within the North Fork valley. <br />• <br /> <br />Maleki Technologies, Inc.
