Services

Wilson Mining (WM) commenced operations in 1990 and is proud to have always been 100% Australian owned and operated.

ROCSIL ® FOAM is a proven product used primarily to fill the voids of roof cavities in underground mines. WM has developed extensive capability since 2002 to apply ROCSIL ® FOAM in a wide array of challenging mining environments including longwall fall recovery.

ROCSIL ® FOAM is a two component phenolic resin product used for cavity filling, air and gas sealing and stabilisation of highly fractured strata. It’s most common use is to fill roof cavities formed by roof falls on longwall faces or development panels.

Proven Capability

The product was first used in Europe in the 1980’s. Capability has been developed by WM since its introduction to the Australian mining industry in 2002 with over 1300 successful Rocsil foam applications in Australia and NZ.

Process

The mixing of resin and catalyst in a volume ratio of 4:1 produces an immediate foaming reaction followed by a rapid expansion of the product to as much as 35 times its original volume. The foam is delivered at a rate of up to 75m3/hour via a lance probe up into the cavity and is retained by minimal formwork. It quickly provides a positive support into the cavity with no shrinkage.
