Technology Data Sheet Mine Dewatering Groundwater is a common problem when mining, and developing a mine below groundwater level presents many challenges. Poorly controlled groundwater will have negative impacts on the safety, efficiency and economics of mining operations. Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining .

Open-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In alone, more than 3, deaths related to mining occurred. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, ). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining .

equipment, which may include a mining loader, shovel or excavator. Loaders lift the ore or waste material onto the trucks for removal from the mine. In an open-pit mine, loader types can include electric rope, hydraulic excavators including backhoe excavators, and front-end loaders (also called wheel loaders) (Er˘celebi and K rmanl, ). mining: Open-pit mining Deposits mined by open-pit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it.
