ACARP Project on Sustainable Landscape Design for Coal Mine Rehabilitation

In 2009/2010 Landforma was involved in an Australian Coal Industry Research Program (ACARP) C18024 investigating “Sustainable Landscape Design for Coal Mine Rehabilitation”.

This project compared waste dump landform design outputs using (a) existing landform guidelines; (b) the Water Erosion Prediction Program (WEPP) runoff and erosion model; and (c) dedicated landform design software (Geofluv). The three landform design approaches were applied at two mine sites in the NSW Hunter coalfield, for landforms sheeted with local topsoil. Landforms developed using the three design methods were then assessed for erosion risk using the SIBERIA landform evolution model, with the impacts of varying vegetation cover for each landform design also being evaluated to assess the importance of cover in ensuring the stability of the designed waste dumps.

This report was published in May 2010 and is available from the ACARP web site

 

Intermat Innovation Awards announced

Mecalac Ahlmann’s Hybrid 12MTX won both the machinery gold award and the special environment prize. Intermat has announced the winners of its innovation awards. There were eight awards in all spread over three categories including a Special Environment Prize.

In the machinery category the gold award went to Mecalac Ahlmann for its Hybrid 12MTX. The Bronze Award (there wasn’t a silver award) went to Fayat for its Beluga hot-mix production plant.

In the Equipment and Components category one of two silver awards (no gold award in this category) went to Made for its Sky Radio 2.0 system which can be fitted to concrete pumps and other high-reach equipment to detect high-voltage power lines. A second silver award went to Flexxaire Manufacturing for its variable-pitch cooling fan. The Bronze award went to Poclain Hydraulics for its motorized hydraulic steerable drive.

In the Services category the silver award (no gold here either) went to Carlson Software for its natural regrade computer software and another silver award went to Keestrack for its Full GPRS transfer controller system.

The Special Environment Prize went to the machinery category winner, Mecalac Ahlmann for its Hybrid 12MTX (pictured). But potential buyers of the hybrid will have to wait quite a while before they can get hold of a machine.

The machine on show at Intermat will only be a concept version. A pre-series machine is likely to be produced later this year, but it will probably be two years from now before models go into production. According to Mecalac, the 9 tonne 12MTX Hybrid has the same performance as the standard 74 kW 12MTX, but it only has a 51 kW diesel motor.

This is due to a 15/30 kW electrical motor-generator being included in place of the pump coupling flange. The main features of the unit, said Mecalac, are its reduced fuel consumption and CO2 emissions and lower noise emissions.
