Most open-cast mines require the removal of overburden and waste material to access the underlying orebody. This activity is known as 'stripping'. By their nature, all open pits become narrower with depth, and consequently the volume of waste to be stripped is largest on the upper benches that must be mined first. The problem is […]

The author demonstrates an approach for analyzing overcasting requirements for a stripping project. This approach to the problem employs indicated trends in the relationship of the weight of the machine (only electropowered draglines are considered) to its ability to do stripping work. Strip mining in the domestic coal industry is contributing a greater …
A planned firing of two separate overburden trim blasts occurred at a mine site in preparation for dragline stripping operations. The production planning schedule at this site required that a dragline begin stripping the overburden. During this process, the dragline bucket contacted an unknown misfire which caused the misfire to initiate.
M.CuM. of Overburden removed during 2005-06. • It is evident that huge amount of OB is removed in NCL. In the coming years OB Removal will further be increased to a great extent, more than 250 Million CuM by 2011-12 with an average stripping ratio of 3.64 for producing 70 MT of coal. Overburden Dump Stability in the Context of NCL
Utilizing dragline for stripping overburden in surface mining is essential for boosting coal productivity and sustaining energy production [].The dragline excavates blasted material only in the case of opencast coal mines [7, 9, 17].The bucket of dragline is huge (more than 60 m 3) and heavy; hence, the impact of fragmentation of overburden …

What Type of Mining Is Associated with Overburden? Surface mining, which is used to extract ore that is close to the earth's surface, generates an abundance of overburden soil. Here are the types of surface mining that generate overburdens: Strip mining. Strip mining is a surface mining technique that removes thin layers of overburden in ...

mine itself and the related life -of-mine assets. The exception to this are those limited circumstances when the stripping activity provides improved access to the whole of the remaining ore body. For example, this might occur towards the end of a mine's useful life when the identified component represents the final part of the ore body to be
The extraction of large quantities of coal in opencast mining requires the removal of upper layers of soil to extract ore components present beneath, resulting in the formation of widespread mine spoils and overburden (OB) dumps, towering to a height of over a hundred meters (Pandey et al., 2021; Singh and Narzary, 2021; Gunathunga et …

The essence of open-pit mining in coal mines is to strip the overlying rock cover of the coal seam and expose the coal seam for mining. Therefore, the recoverable coal reserves depend on the extent of the stripping operation. The method used for open-pit coal mines conducting year-round stripping operations is "mining while stripping."

The Federal Surface Mining Law enacted in 1978 is now being translated into regulations which must be followed in future coal mining. Substantial change to mining procedures is required to maintain stricter air and water control while mining and to return the mined out land to equal or better use than before. These changes do not come easy; and in most …
