The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.
Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.
Open cast coal mining involves various operations e.g overburden removal, drilling, blasting, mineral loading, haulage and unloading that generate particulates due to various mechanisms.

The open-cast mine prepares the ground for recultivation itself. Spreaders first tip clay, sand and gravel into the excavated areas and then place a drainage layer made of water-permeable material over the top. Nowadays, slopes and troughs are designed to look as natural as possible, which means that they are as irregular as nature itself.
