Surface Coal Mining Methods In Australia

Surface Coal Mining Methods in Australia 5 2. Open cut mining methods strip mining Large-scale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significan t developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex andThe first task in open pit mining is to remove the top soil, subsoil, and overburden rocks in sequence. The overburden is dumped separately. It can be reverted for replacement in reverse order. The next stage is to open the mineralized ground as the first slot, known as a box cut. The slot is then expanded to form a bench system.

Open Pit Mining General Overview Protect Ecuador

In mining, it is most commonly the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is removed during surface mining. Because open-pit mining is employed for ore deposits at a substantial depth underground, it usually involves the creation of a pit that extends below the groundwater table.Open cut or surface mining in coal is a suitable choice when coal seams are closer to the natural surface. It is an effective method of retrieving a higher proportion of coal when compared to underground mining. The basic process involves: 1) Exploration 2) Geological Modelling 3) Mine Design 4) Top Soil Stripping 5) Drilling & Blasting
