Affected The Environment.open Cast Mining Operations Result In Dumping Of Overburden On Un Mined Area Which Is Consolidated And Unconsolidated Materials Overlying The Minerals ,And Is Required To Be Removed.
‘overburden’ or ‘waste rock’) that must be moved or excavated to allow access to the metallic ore deposit. Material from these stockpiles, along with operational overburden from the last six years of mining, will be placed within the open cut upon cessation of mining. All of these methods remove the waste material or the overburden, which is above the desired resource.
Overburden Handling Activities Start At The Beginning Of The Mining Project, When A Huge Amount Of Material From Initial Underground Development Or Stripping Is Removed For Site Preparation [3] , [4].
The overburden is dumped out of pit or in mined out areas for later rehabilitation. For most mining projects, the quantity of overburden generated by mining is enormous. Strip mining can be used to remove coal, clay, limestone and other minerals, but coal is the most important mineral extensively removed by stripping operations.

Field Clues* To Overburden Quality And Selective Testing Methods* May Be
Two main activities of the surface mining operations are the overburden removal and its transport to the disposal areas. The principal overburden excavation machines are draglines, bucket wheel, excavators, power shovels, dozers,. The movement of overburden in strip mining is called the casting process.
In The Last 30 Years, Our Mining Operations Have Achieved Immense Success In Carrying Out Operations With Expertise In All The Major Mines Of Odisha.
In this topic, we will look at some of the characteristics of these excavation. Overburden handling has important impacts on surface mining projects and has to be carefully planned considering both mining activities and site rehabilitation ,. In the previous topic, we saw that blasting is the mining operation used to break the rock mass in order to facilitate the removal of the overburden.
