Vegetative Stabilisation of batters and Spoil dumps on Asian Pacific Mine Sites
Vegetative stabilisation of spoil dumps, batters and sub-soil heaps is difficult due to low organic matter, uncompacted material, gradient, deficient or toxic nutrients and lack of rainfall or water holding capacity. These trials use various techniques to apply organic mulch to each batter profile after soil testing has identified any deficient or toxic element. Vegetative species are chosen based on the surrounding analogue sites, government and site requirements. Results to date indicate that correct application of high levels of organic matter through hydraulic application is successful within the climatic zones assessed. The current sites are within Australia, Philippines and India with future sites to be considered in Papua, Malaysia and Pakistan. Significant impacts in vegetative coverage, organic matter increase and a reduction is soil loss has been measured during the first six months after application. Ongoing assessment will measure vegetative coverage, organic matter changes, soil loss and carbon sequestration.
