Executive Summary

1.0 Project Land restoration / reclamation monitoring of 10 opencast

coal mines of Western Coalfields Ltd. (WCL) 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 77.93 Km2 of the 10 projects of WCL, Viz. Sasti, Padmapur, Durgapur, Mugoli, Umrer, Ukni, Niljai, New Majri, Pimpalgaon and Ghugus considered for monitoring during 2010-11; total mined out area is only 53.02 Km2 (68.03%) of which 25.35 Km2 area (47.81%) has been planted, 20.13 Km2 area (37.97%) has been backfilled and 7.54 Km2 area (14.22%) is under active mining. It is evident from the analysis that 85.78% areas of the OC projects has already been reclaimed. Project wise details are given in Table-1 & Fig -1.

• On comparing the status of land reclamation for the year 2010 with respect to the year 2009 in different OC projects, analysis reveals that area of land reclamation has increased from 42.50 Km2 (Yr. 2009) to 45.48 Km2 (Yr. 2010). Out of 10 projects of WCLGhugus OC (95.05%) ranks on top for land reclamation followed by Sasti OC(92.72%) and New Majri OC (91.07%).

• Area of plantation has increased from 22.73Km2 (Yr.2009) to 25.35Km2 (Yr.2010) in WCL. This increase of 2.62 Km2 in area of plantation in one year is the result of the efforts of the WCL taken up towards environmental protection.

• It has been also observed that in certain projects of WCL viz

Padmapur and Durgapur plantation percentage in the year 2010 has reduced marginally in respect to the previous year i.e. 2009, in spite of increase in plantation area. This has occurred primarily due to increase in total mined out area in those subsidiaries as depicted in Table – 1.

1.0 Background

1.1 All human activities are based on the land which is most scarce natural resource in

our country. Per capita land availability in India is the lowest owing to high

population density and less land mass. Out of total 329 million hectare (mha) land

mass of the country, coal mining is limited to only on 0.10% (0.36mha) area. As per

XI Plan, to meet the energy demand of the country, coal production would be raised

to 680 million tonnes by the end of the year 2011-12 for which about 40,000 hectare

of land would have to be acquired for coal mining projects. It has been envisaged

that 85% coal production would be from opencast mines, which causes land

degradation due to ground breaking. There is an urgent need to reclaim and restore

the mined out land for its productive use for sustainable development of the coal

mining. This will not only mitigate environmental degradation, but would also enable

coal companies to offer the restored lands to displaced families which would help in

creating a more congenial environment for land acquisition in future.

1.2 Keeping above in view, Coal India Ltd. requested Central Mine Planning & Design

Institute (CMPDI), Ranchi who has well a equipped remote sensing facilities and

capabilities to develop an effective system of surveillance for land reclamation/

restoration for all the opencast coal mines with production of more than 5 million cu.

m. per annum (coal + OB taken together) based on remote sensing satellite data,

regularly on annual basis for sustainable development of mining operation within

command area of CIL and its subsidiaries. The annual land reclamation/restoration

status report of all such mines to be put on the website of CIL,

(www.coalindia.nic.in), CMPDI (www.cmpdi.co.in) and the concerned coal

companies in public domain. Detail report to be submitted to State Pollution Control

Board and MoEF and concerned CIL’s subsidiaries. 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.

1.3 CMPDI undertook the above assignment, and the present report is embodying the

finding of the study carried out during 2010-11 for the WCL projects. Similar study

for the opencast projects of WCL has been carried out for the years 2008 & 2009 as

well.

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:

CMPDI

Job No 561410027/(WCL) 3

Fig.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.

neighbouring pixels using ERDAS IMAGINE 9.3 s/w. 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 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 v. 9.3 s/w.

• 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 are carried out in the field

and necessary corrections if required, are incorporated before map finalization.

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-of dates.

4.0 Work Plan

4.1 Opencast projects of WCL producing more than 5 million cubic m. (Coal + OB

together) during the year 2010 -11 have been taken up for land restoration /

reclamation monitoring based on the RESOURCESAT-1(LISS-IV) satellite data

using ERDAS Imaging digital image processing s/w on GIS platform. Land

reclamation monitoring will be carried out regularly on annual basis to assess the

progressive status of land restoration / reclamation in the above opencast mines.

The report has been uploaded in the website of CMPDI, CIL & WCL in public

domain.

5.0 Land Reclamation Status in Western Coalfields Ltd.

5.1 Following 10 OC projects producing 5 million cubic m. and more (Coal + OB

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

monitoring based on satellite data of the year-2010 :

• Sasti

• Padmapur

• Durgapur

• Mugoli

• Umrer

• Ukani

• Niljai

• New Majri

• Pimpalgaon

• Ghugus

5.2 Area statistics of different land use class present in OC projects in the year 2010 is

given in Table 5.1. Land use maps derived from the satellite data is given in

Drawing no. HQ/REM/1/A4/10/01 to HQ/REM/1/A4/10/10 . Changes in land use

status are shown in Fig. 5.1 - 5.10. Field photograph showing plantation on OB

dump/backfilled area are also enclosed.

5.3 Study reveals that 85.78% of mining area has already been reclaimed by WCL out

of which 47.81% area has been revegitated and 37.97% area are backfilled.

5.4 After analyzing the satellite data of year 2009 vs. 2010 it is evident that plantation

carried out on backfilled area, OB dumps as well as under social forestry in the

mines of WCL has increased from 22.73 Sq. Km. (2009) to 25.35 Sq. Km.(2010) in

span of last one year. Whereas in span of last three year plantation has increased

from 17.18 Sq. Km (Yr.2008) to 25.35 Sq. km. (Yr.2010). This substantial increase

in the plantation area is due to the massive efforts taken up by WCL towards

environmental protection.

CMPDI

Job No 561410027/(WCL) 7

5.5 It has been also observed that in certain projects of WCL viz Padmapur and

Durgapur plantation percentage in the year 2010 has reduced marginally in

respect to the previous year i.e. 2009, in spite of increase in plantation area. This

has occurred primarily due to increase in total mined out area in those subsidiaries

as depicted in Table – 1.

5.6 Study indicates that coal mining in the above projects of WCL is limited to only

68.04% of the total mining leasehold area.

5.7 Study further reveals that about 85.78% of the total mined out area in the above

projects are reclaimed and balance about 14.22% area is under active mining.

5.8 Out of 10 projects of WCL considered for analysis, Ghugus OC (95.05%) rank on

top for land reclamation followed by Sasti OC (92.72%) and New Majri OC (91.07%)
