Summary: In early 1987, the Patience Lake potash mine near Saskatoon, Saskatchewan, was closed due to uncontrollable flooding. Water inflows were first encountered during routine mining in 1975 at the south boundary of the mine lease. Underground grouting and construction of bulkheads limited the flow but did not completely stop it. Subsequent seismic surveys showed that the mine had approached the edge of a large collapse structure in which the salt and potash had been partly dissolved and removed by...

Summary: Increasing mine depth and panel length combined with faster longwall retreat rates necessitated a change from the passive support of steel sets to roofbolts at the Phalen Colliery in the Sydney Coalfield. Development drivage rates achieved with roadheaders installing steel sets would not support the retreat rates of the longwall panels. Also, front abutment pressures from the longwall retreat were seriously deforming the steel sets. In 1991, full column resin grouted roofbolts were introduced...
