Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

Safety and health in opencast mines VI The practical recommendations of this code of practice are intended for the use of all those, in both the public and private sectors, who have responsibility for safety and health in opencast mining. The code is not intended to replace national laws or regulations or accepted standards.
Open cut coal mining methodologies. The open cut mining method requires the efficient removal of overburden and interburden strata in order to access coal seams. An open cut pit is normally commenced through excavation of a box cut or initial slot into an area where the pit basal seam subcrops and the stripping ratio is low.
China''s largest openpit coal mine is located in Haerwusu in the Inner Mongolia Autonomous Region. It started production in 2008, and is operated by Shenhua estimated coal output was forecast at 7 million tonnes in the fourth quarter of 2008.
Jul 31, 2017· Although the mine is an open pit, some excavation is required. Openpit mines are used to extract ores such as coal, copper, gold, iron, and aluminum. When an openpit mine is developed, there are a number of environmental, safety, and costrelated factors to consider, including noise and air quality and animal habitats. 27.
