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

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.

together) of Northern Coalfields Ltd. have been taken up for land reclamation

monitoring during the year 2016:

Amlohri

Nigahi

Jayant

Dudhichua

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.
