The Advantages of Open Pit Mining Sciencing

2018-3-13  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 is the preferred method for mining gold, silver, and uranium. This type of mining is also used to dig for coal
