Drilling on hole is the most important
operation in open cast mine. There are
three types of drilling machines and two
compressors are available.
Types of drilling machines:
1. IDM-45D - 8.5” dia
2. IBH-10 - 6” dia
3. ICM-260 - 4” dia
Why drilling is done?
Firstly particular site is examine for drilling.
After drilling is done blasting bombs are
inserted in the holes.
After this procedure blasting takes place and
the material is loaded to dumpers by the
These materials then send to crushing plants
for further reducing in dimension nearer to 25
mm of size.
DRILL RODE SIZE:
length : 7.62m
Diameter : 152mm (6”)
Total drill depth : 30.48m (100”)
Number of rods : Four
In RSMML ltd there are two
(a) Low grade ore crushing
(b) High grade ore crushing
LOW GRADE ORE
Obtain from open cast mines.
It contains 16% to 19% of phosphate.
This low percent ore is made rich upto
34% of phosphate in an IBP plant.
In LGO plant cone crusing and double
face jaw crushing are used.
Then the final product is dumped in the
dumping yard and then sold in the
HIGH GRADE ORE
There are two HGO plants in RSMML.
(1) Old crushing plant – capacity 120
tones/hr,established in 1971.
(2) New crushing plant- capacity 180
tones/hr,established in 1992.
It contains 34% of phosphate and can
be directly sold to the market.
Jaw crushers are used in HGO plant.
The low grade ore which contain 16% to
19% phosphate is treated with some
chemicals like phosphoric acid,
Then it converted into high grade ore
with 34% phosphate concentration.
After this the output product is dumped
in the dumping yard.
From dumping yard these final product
is loaded in the dumpers.
There can be more than 200 products made
from treating this final material with different
ingredient and then they can be directly
For final product the material is given to
many small companies like Rama Phosphate
etc which makes final product.
