Executive Summary
1.0 Project Land restoration / reclamation monitoring of 10
opencast coal mines of Northern Coalfields Ltd. (NCL) producing 5 million cu.m. and more (Coal+OB) per year based on satellite data, regularly on annual basis.
2.0 Objective Objective of the land restoration / reclamation
monitoring is to assess the area of backfilled, plantation, social forestry, active mining area, water bodies, and distribution of wasteland, agricultural land and forest in the leasehold area of the project. This will help in assessing the progressive status of mined land reclamation and to take up remedial measures, if any, required for environmental protection.
3.0 Salient Findings
Out of the total mine leasehold area of 174.28 Km2 of
10 projects Viz. Amlohri, Nigahi, Jayant, Dudhichua, Khadia, Krishnashila, Bina, Kakri, Jhingurdah and Block-B considered for monitoring during year-2016; total excavated area is 116.97 Km2 (67.12%) of which 54.96Km2 area (46.99%) has been planted, 32.61 Km2
area (27.88%) is under backfilling and 29.40 Km2 area (25.13%) is under active mining. It is evident from the analysis that 74.87% area of the OC projects are under reclamation (biologically and technically) and balance 25.13% area is under active mining. Project wise details are given in Table-1 & Fig-1.
On comparing the status of land reclamation for the year 2016 with respect to the year 2015 in different projects, it is evident from the analysis that area of land reclamation has slightly reduced from 88.55 Km2 (Yr. 2015) to 87.57 Km2 (Yr. 2016). Out of 10 projects of NCL, maximum land reclamation has been carried out in Jhingurdah project (100%), in this project, production from current seam is almost over. followed by Kakri(84.88%) and Nigahi (78.72%).
Area of biological reclamation (plantation) has reduced marginally from 57.52Km2 (Yr. 2015) to 54.96 Km2 (Yr. 2016). However, area of technical reclamation
CMPDI
Job No 561410027 vi
(backfilled area) has marginally increased from 31.03 Km2 (Yr. 2015) to 32.61 Km2 (Yr.2016) in NCL.
The active mining area has significantly increased from 26.50 km2 (year 2015) to 29.40 km2 (Year 2016).
The production capacities of most of the OC mine in NCL have been increased to cater to the power demand of the Nation. Due to this the generation of overburden has also increased. Since the mine leasehold areas have no other space available for dumping these additional overburden generated are being dumped on vegetated dumps.

1.0 Background
1.1 Land is the most important natural resource which embodies soil, water, flora, fauna
and total ecosystem. All human activities are based on the land which is the
scarcest natural resource in our country. Mining is a site specific industry and it
could not be shifted anywhere else from the location where mineral occurs. It is a
fact that surface mining activities do effect the land environment due to ground
breaking. Therefore, there is an urgent need to reclaim and restore the mined out
land for its productive use for sustainable development of mining. This will not only
mitigate environmental degradation, but would also help in creating a more
congenial environment for land acquisition by coal companies in future.
1.2 Keeping above in view, Coal India Ltd. (CIL) issued a work order vide letter no. vide
their letter No CIL/WBP/ENV/2011/4706 dated 12/10/12 for the period 2012-13 to
2016-17. According to this work order all mines in CIL with output capacity of 5
million cu. m (coal +OB) shall be monitored every year and all mine below this
capacity shall be monitored at an interval of 3 years. All coalfields in CIL shall also
be monitored at an interval of 3 years as per a defined plan. This report covers the
period 2016-17. The results of land reclamation status of all such mines are being
uploaded every year on the website of the concerned coal companies in public
domain. Detail report is submitted to Coal India and respective subsidiaries
1.3 Land reclamation monitoring of all opencast coal mining projects would also comply
the statutory requirements of Ministry of Environment & Forest (MoEF).Such
monitoring would not only facilitate in taking timely mitigation measures against
environmental degradation, but would also enable coal companies to utilize the
reclaimed land for larger socio-economic benefits in a planned way.
1.4 Present report is embodying the finding of the study based on satellite data of the
year 2016 carried out for all the OC projects for Northern Coalfields Ltd.

2.0 Objective
Objective of the land reclamation/restoration monitoring is to assess the area of
backfilled, plantation, OB dumps, social forestry, active mining area, settlements
and water bodies, distribution of wasteland, agricultural land and forest land in the
leasehold area of the project. This is an important step taken up for assessing the
progressive status of mined land reclamation and for taking up remedial measures,
if any, required for environmental protection.
3.0 Methodology
There are number of steps involved between raw satellite data procurement and
preparation of final map. National Remote Sensing Centre (NRSC) Hyderabad,
being the nodal agency for satellite data supply in India, provides only raw digital
satellite data, which needs further digital image processing for extracting the
information and map preparation before uploading the same in the website.
Methodology for land reclamation monitoring is given in given in fig 2. Following
steps are involved in land reclamation /restoration monitoring:

Figure :2 Methodology for Land Reclamation Monitoring
3.1 Data Procurement: After browsing the data quality and date of pass on internet,
supply order for data is placed to NRSC. Secondary data like leasehold boundary,
topo sheets are procured for creation of vector database.
3.2 Satellite Data Processing: Satellite data are processed using ERDAS IMAGINE
digital image processing s/w. Methodology involves the following major steps:

Rectification & Georeferencing: Inaccuracies in digital imagery may occur due to
‘systematic errors’ attributed to earth curvature and rotation as well as ‘non-
systematic errors’ attributed to satellite receiving station itself. Raw digital images
contain geometric distortions, which make them unusable as maps. Therefore,
georeferencing is required for correction of image data using ground control points
(GCP) to make it compatible to SoI toposheet.
Image enhancement:
To improve the interpretability of the raw data, image enhancement is necessary.
local operations modify the value of each pixel based on brightness value of
neighbouring pixels using ERDAS IMAGINE s/w v2014 and enhance the image
quality for interpretation.
Training set selection
Training set requires to be selected, so that software can classify the image data
accurately. The image data are analysed based on the interpretation keys. These
keys are evolved from certain fundamental image-elements such as tone/colour,
size, shape, texture, pattern, location, association and shadow. Based on the
image-elements and other geo-technical elements like land form, drainage pattern
and physiography; training sets were selected/identified for each land use/cover
class. Field survey was carried out by taking selective traverses in order to collect
the ground information (or reference data) so that training sets are selected
accurately in the image. This was intended to serve as an aid for classification.
Classification and Accuracy assessment
Image classification is carried out using the maximum likelihood algorithm. The
classification proceeds through the following steps: (a) calculation of statistics [i.e.
signature generation] for the identified training areas, and (b) the decision boundary
of maximum probability based on the mean vector, variance, covariance and
correlation matrix of the pixels. After evaluating the statistical parameters of the
CMPDI
Job No 561410027 5
training sets, reliability test of training sets is conducted by measuring the statistical
separation between the classes that resulted from computing divergence matrix.
The overall accuracy of the classification was finally assessed with reference to
ground truth data.
Area calculation
The area of each land use class in the leasehold is determined using ERDAS
IMAGINE v2014 software.
Overlay of Vector data base
Vector data base created based on secondary data. Vector layer like drainage,
railway line, leasehold boundary, forest boundary etc. are superimposed on the
image as vector layer in the Arc GIS database.
Pre-field map preparation
Pre-field map is prepared for validation of the classification result
3.3 Ground Truthing:
Selective ground verification of the land use classes was carried out in the field in
March 2017. All points noted for verification were visited.
3.4 Land reclamation database on GIS:
Land reclamation database is created on GIS platform to identify the temporal
changes identified from satellite data of different cut-off dates.

4.0 Land Reclamation Status in Northern Coalfields Ltd.
4.1 Following 10 OC projects producing more than 5 million cubic m. (Coal + OB
together) of Northern Coalfields Ltd. have been taken up for land reclamation
monitoring during the year 2016:
Amlohri
Nigahi
Jayant
Dudhichua
Khadia
Krishnashila
Bina
Kakri
Jhingurdah
Block-B
4.2 Area statistics of different land use class present in the mine leasehold of the above
projects for the year 2016 are shown in the Table - 2. Land use maps derived from
satellite data are shown in Plate 1 - 10. Land reclamation status of the above
mentioned 10 projects, were prepared regularly from the year 2009, to year 2016.
Annual change in the different land use classes based on satellite data for the year
2015 and 2016 are depicted in Bar Charts in Fig. 4.1 - 4.10.
4.3 Study reveals that out of total excavated area of 116.97 km2, 67.12% of area is
under reclamation by NCL out of which 46.99% area has been revegetated and
27.88% area is under backfilling. There is marginal reduction 0.98 Km2 under
reclamation in NCL with respect to the year 2015. This reduction is due to high rate
of production as per enhanced capacities of the mines. Area has reduced but the
height of reclaimed dumps have increased.
CMPDI
Job No 561410027 7
4.4 After analyzing the satellite data of year 2015 vs. 2016 it is observed that area of
plantation has decreased from 57.52 km2 in 2015 to 54.96 km2 in 2016 due loss
of some plantation because dump heights were increased due to high overburden
removal and no additional space available for dumping of overburden material.
4.5 Out of 10 projects of NCL, maximum land reclamation has been carried out in
Jhingurdah Project (100%) followed by Kakri (84.88%) and Nigahi (78.72%). It may
be noted that in Jhingurdah OC Mine production from upper mineable seams is
almost complete.
4.6 The production capacities of most of the OC mine in NCL have been increased to
cater to the power demand of the Nation. Due to this the generation of overburden
has also increased. Since the mine leasehold areas have no other space available
for dumping these additional overburden generated are being dumped on vegetated
dumps.
