case study 1: top-of-rock mapping the depth to top of rock can be extracted readily from veloc - ity-depth graphs since overburden has a slower shear-wave veloc - ity than bedrock (figure 1). case study 1 is from western penn - sylvania and involves the use of 1d masw soundings to localize a surface coal mine highwall. during surface mining,
considerable methane resources exist in abandoned coal mines. however, methane extraction from abandoned mines in china is still in the exploratory stage. this study presents technologies and engineering practices suitable for the extraction of gob methane from abandoned mines using surface vertical wells, including methane drainage systems, well bottom locations, and an intermittent
rising water levels within abandoned mine workings have been described in detail (adams and younger, 2001; robinson, 2000) particularly in relation to the impacts on the water environment. another impact of rising groundwater levels is the potential for an increase in gas pressure as a rising hydrostatic head displaces gas within abandoned mines and reduces gas storage capacity.

of wells prior to the 1950s either were not plugged at all or plugged with very little cement in them. additionally, when cement was required, the regulations was so vague that wells were plugged with brush, wood, rocks, paper and linen sacks, or a variety of other handy items that would serve to hold a sack of cement (ide et al., 2006).

when an underground pipe or structure is abandoned, the two basic options that are considered are (1) pipe abandonment, or (2) removal. the removal option is often not feasible or cost-effective. a structure or pipeline that is abandoned in place without filling may deteriorate and lead to ground subsidence which in turn creates the potential for water erosion, impacting future land use and
