Abstract:
Mobile paste backfill applications are becoming more and more common as orphaned and abandoned mines are becoming challenges or even impediments to urban or recreational development. In addition, the public risk and safety issues associated with these orphaned sites are bringing remediation programs to the forefront. These sites are left in the hands of local, regional and federal governments to deal with, and they typically lack the resources from a financial and technical perspective to effectively reduce the risks these sites pose. The technical challenges of early 20th century mine plans, no current underground access, logistics and proximity to local communities associated with these orphaned sites, makes mobile paste backfill a viable option. This particular application of paste technology has not, to date, been widely utilised but is a growing area of need. This paper will discuss two case studies from the past decade of work on mobile paste applications ranging from a resort development program to a crown pillar stability remediation program.
