Hello everyone in this question we will be discussing about sub -surface mining.
00:07
It is basically the extraction of metal ore or fossil fuel resources from beneath the surface of the ground.
00:22
There are different types of mining like there is strip mining.
00:28
It is a process of removing rock and soil in strips to get to the valuable mineral pores below.
00:42
And after miners extract the resources, they put back the leftover rock and soil called the mining spoil or tailings to fill the hole.
00:53
To fill the hole.
00:54
There is mountain top removal.
00:56
This is similar to the strip mining but it is done at the larger scale and this technique removes large amount of rocks and soil, that is the whole mountain tops to access the resources buried deep inside the mountain.
01:14
We have pit mining.
01:17
Pit mining involves a digging large digging of large hole to gather rocks and minerals from the earth's crust.
01:26
There is placer mining.
01:28
Which is a way of obtaining mineral and metal resources from loose river sediments...
