allotment against the scheduled time line of 44 months, i.e. on
11.12.2017.
• Coal production commenced from 28.04.2018.
• Mining plan approved
…… Aug- 2008
• Mine Closure plan Approved
…… Sep- 2017
• Environment Clearance Obtained .….. Feb- 2016

Reasons for revision of Mining Plan
As per new Guidelines for Revision of Mining Plan
The mining plan may be modified for

for change in method of mining;

change in leased area;

conservation of minerals;

addition of reserve by way of proving of reserve in the existing lease area;

for changes in final mine closure conditions;
19
Reasons for revision of Mining Plan
After 2024-25 there will be no place for dumping the Over burden.
The present internal dump yard is having permission to dump upto
Ground Level only.
-To dump the re-handled OB the height of the internal dump yard has to
be increased, which requires revision of Mining plan and EC.
-The present external OB dumpyard-2 has to be re-handled and to be
dumped in the internal dump yard for removal of coal after 2 years.
20
Revision of Mining Plan-Working Plan
Mine has the production capacity of upto 2 more years as there is no place to dump ob extracted after two years.
-The present ob external dumpyard-2 has to be re-handled and to be dumped in the internal dump yard for removal of coal
beyond 2 years.
- The present internal dump yard is having permission upto Ground Level only. To dump the re-handled OB the height of the
21
internal dump yard has to be increased, which requires revision of Mining plan and EC.
Reasons for Revision of Mining Plan
Tadicherla -1 Mining plan revision comes under the below category
for change in method of mining;
To increase the internal dump height above
the ground level
change in leased area;
To extract the coal with in the New GR
boundary
conservation of minerals;
To extract upto 6 seam
addition of reserve by way of proving of reserve
in the existing lease area;
As per New GR total reserves estimated as
89.85 MT
for changes in final mine closure conditions; or
To change the final void as it is instead of reclaiming
the land upto ground level
