Calculation of overburden and coal seam correlation

How do we calculate the volume of over- burden?

posted by Taufiyogi blogger

The results of measurements of the rock layers by drilling Drill Log Data will be obtained . So more and more drilling will be many drill log data created by a geologist who will be followed by a correlation of rock layers.
Ideal example :
Profile Drilling A , B , C , and D


drilling data, own by taufiyogi blogger


t1, t2 is not the thickness of the coal seam but it is a sub overburden . Total Depth is the maximum depth drilled , measured from the ground level of the data based on the topography of the area .
t1 + t2 = sub overburden
Total OB = ( t1 + t2 ) x Area of ​​Location
( T1 + t2 ) / tc ( coal) = sub Stripping Ratio
Total Stripping Ratio ( SR ) = Total OB : Total Coal seam (tc).
Therefore, to determine the average stripping ratio, should be a lot of drilling in the region with the distance ( interval ) is desired . if the distance is getting closer the more detailed data obtained anyway.
 

The example image correlation of rock layers

coal seam corelation--taufiyogi blogger


The picture above is just an illustration only, whereas the reality may be more variable .
The purpose of correlation of rock layers is to connect the layers of rock types according to the kind of data drill or drill logs , to get a thick rock layers in total , for the manufacture of stratigraphic modeling, reserve calculations and mine design.
Note : in calculating the volume of coal to be multiplied by 1.3 Coal Density ( kg / m3 ; tonnes / m3 ; kg / feet3 ; ton / feet3 ) it will get a weight unit metric tons.

The next stage is the exploitation and production.
