1.0 INTRODUCTION

1.1 Background :

Chairman, Coal in a “Quarterly Review meeting” held in August, 2007

suggested that CMPDI should take up study for reclamation of the old abandoned

voids in CCL command areas (Annexure-I). Director (T/P&P), CCL requested CMPDI

to take up study for filling up of old abandoned voids for land reclamation in CCL

command areas through his letter dated 16.8.2007. CCL had proposed to identify at

least 5 voids initially in the first phase and also to identify available overburden dumps

for filling up the voids immediately. Accordingly CMPDI had carried out the 1st phase of

work & submitted its report to CCL on 22.11.2007.

Further to the above Director (T/O), CCL requested CMPDI to identify the

voids in other areas of CCL command areas vide his letter no. GM(E&F)/08/360 dated

25.03.2008 (Annexure-II). On the basis of discussion with CCL, CMPDI submitted the

offer along with scope of work vide letter no. CMPDI/B.D./B(Survey)/363 dated

06.06.2008 (Annexure-IIA), on the basis of which CCL placed work order vide letter no.

CGM/P&P/08/1333-35 dated 12.09.08 (Annexure-IIB). On the basis of time schedule

submitted by CMPDI in it’s offer dtd. 06.06.2008, CGM(P&P), CCL has fixed their order

of priority vide their office note dtd. 30.06.2008 (Annexure-IIC). Accordingly, the Report

of area was submitted vide letter dtd. 03.11.2009 & Report of

1.2 Previous Studies :

The committee, constituted by MOC, for “Monitoring, Rehabilitation of Mines

and Afforestation Work” held its 1st. meeting on 23.07.2003 and recommended that

CMPDI should prepare detailed plan for reclamation of old abandoned mine voids of

CCL areas as water reservoirs (Annex-I/A). Environment Division of CMPDI submitted

the reports for development of the voids as water bodies for 8 areas of CCL in

April’2004. Summarised extract of those reports is given in Annexure-I/B.

1.3 Scope of Work :

Scope of work under present study is as follows (refer annexure II/A & II/B) :

I. Interaction with area & project officials and collection of mine plans showing all

abandoned voids & related dumps & other important surface features.

II. Ground checks of the identified voids & dumps as well as recording its tentative co-

ordinates with the help of DGPS and nomenclature for unique identification.

III. Study of satellite imagery location plans for identification & mapping of the voids &

dumps area/mine-wise.

IV. Collection of detailed survey plans with spot levels of the identified voids &

associated dumps wherever available.

V. Survey of the voids and dumps, wherever detail survey plan is not available in the

Project/Mine.

VI. Scanning & digitization of the available plans for creating database.

VII. Computation of volume through computerized cross-sections for each set of voids

& dumps.

VIII. Submission of area-wise report which will contain broadly the following:

Job No. 60308090

a. Coalfield & mine-wise land use/cover map in appropriate scale.

b. Mine-wise survey plan of voids & dumps.

c. Representative cross section of voids & dumps.

d. Volume of voids & dumps.

e. Lead distance of associated dumps from void.

f. Any other drawing as may be required.

It may be noted that Geo-mining & Environmental study is kept out of

present scope of work as clarified in CMPDI’s letter: CMPDI/BD/BE(Survey)/439,

dated: 23.07.08 (Annexure-II/D).

2.0 Methodology

2.1 General :

The surface maps were collected from the respective areas and collieries

showing important surface features, void locations and the limit of the underground

works, wherever present. These maps were utilised for identification and labeling of

quarries and features on the Satellite Imagery Maps to generate accurate Quarry

location maps showing relative positions of all the Quarries (Voids), available dumps

and other surface features. In this regard, identified voids (with unique code), quarry

name & mined seams as per the plans collected are given in Table-1 below:

2.2 Mapping of voids & Dumps by Remote Sensing Analysis:

Data of IRS Resourcesat LIS- IV satellite was used as primary data source

in the present study. The details of the satellite data are as follows:

Satellite: Resourcesat (P-6) LIS- IV

Bands: 2,3,4,

Path: 105 Rows: 055

Date of Pass:06/10/2011

Spatial Resolution: 4.8x4.8m

Satellite data image is a graphical presentation of numerical data

characterizing different features or objects of the earth’s surface. Extraction of

information from such image requires that features such as land use/cover details,

landforms, drainage, etc, be identified and their boundaries (or edges) be defined. The

identification of features requires processing for correction of geometric distortions,

noise filtering and calibration of the digital data, which is referred to as “image

processing”. The extraction of meaningful information about the features by image

enhancement and geotechnical interpretation using a very image element in an image

is termed as “image analysis”.

All the above-mentioned operations are categorized into one (or more of the

following three sequential operations: (a) image processing, (b) geo-referencing and

(c) image enhancement.

Open quarries and OB dumps were identified in the processed False Colour

Composite (FCC) imagery of the study area on the basis of tone, texture and other

characters. Those were then correlated with the colliery maps to put the identification

labels and these have been shown in Plate-I & Plate II.

Job No. 60308090

2.3 Assessment of Land cover within the Study area:

Quantitative estimation of the land use and vegetation cover areas in the

study area has been carried out. Following features have been extracted and collated

on the maps after geo-referencing and intensive ground checks (Plate-I & Plate-II).

Vegetation cover / Land use classes identified in the study area

LEVEL –I LEVEL-II 3.1 Dense Forest 3.2 Open Forest 1 Vegetation Cover 3.3 Scrub 3.4 Plantation under Social Forestry 3.5 Plantation on OB Dumps 5.1 Coal Quarry 2 Mining Area 5.2 Barren OB Dump 4.1 Waste upland with/without scrubs 3 Wasteland 4.2 Gullied Barren Land 4.3 Sand

2.1 Crop Land 5 Agricultural Land 2.2 Fallow Land 1.1 Urban 6 Settlements 1.2 Rural 1.3 Industrial 7.1 Road 7 Infrastructure 7.2 Railway Line 7.3 Rope way

2.4 Estimation of Volume of the voids & dumps :

Quantitative estimation of excavation volume of the voids & surrounding

dumps are essential as basic inputs for computation of cost for filling up the voids.

Accurate survey plans with spot levels of both the voids and dumps are required for

the purpose. Survey plans, wherever available, have been collected from the colliery

and the rest have been prepared based on data acquired by survey carried out by

CMPDI. Table2 given below indicates the sources of the plans:

Job No. 60308090

2.4.1 Field survey :

Reconnaissance survey of the voids, dumps & its associated areas were

conducted first. Thereafter, a closed traverse survey using Electronic Total Station

(ETS) was conducted from the nearest reference survey stations with respect to

National Coal Grid (provided by colliery survey department) and established a network

of survey control points within the interest area.

Detail surveying was also conducted using ETS having 2 sec. accuracy from

these control stations to collect sufficient survey data of the voids and dumps as per its

profile. In some voids, the floor data could not be taken as those were water logged. In

such cases, floor data has been taken from the floor contour plan of the bottommost

worked out seam from the Geological Report of the Area.

2.4.2 Preparation of Plans & Cross Sections :

The survey data were processed in order to obtain X, Y and Z (R.L.)

coordinates of the points surveyed. Necessary editing in the database file was done

based on the field observations, wherever required. Detail survey plans, collected from

the collieries, were scanned and digitized to create database. Plans on suitable scales

showing spot levels, cross-section lines etc. have been prepared from the processed

data using LISCAD and AUTOCAD software and enclosed as plate nos. III – VII.

Cross-sections were generated at every 10m interval in the direction

perpendicular to the benches, for quarries and dumps, with the help of LISCAD and

Job No. 60308090

AUTOCAD software. Cross-sectional areas have been determined through computer

using AUTOCAD software.

2.4.3 Calculation of Volume :

The Volume computation of voids & dumps has been done through cross-

sectional method using “trapezoidal formula”. The volumes of voids, dumps and lead

distance for each void & dump have been provided in section-3.0.

3.0 QUANTITATIVE ESTIMATES FOR THE IDENTIFIED VOIDS AND DUMPS

3.1 General :

Volume estimate of the selected voids and dumps has been done as per the

methodology explained in sec.2.4 and quantitative data are given in Table- 3.

Summarised information in respect of each void and dump is presented in the following

sections.

4.0 COLLIERYWISE DATA OF VEGETATION COVER AND LANDUSE

4.1 General:

Job No. 60308090

Detail analysis of the digital satellite data was carried out as described in sec.2.5

above to delineate and quantify different land use and vegetation cover zones. The

data for the total study area ( Argada Area) is presented in Table-4A to 4E, (Giddi–A,

Religara, Giddi-C, Argada & and Sirka) . Most important fact emerging from this

analysis is that land covered by water bodies is only 34.21 % in the whole Area,

whereas it varies between 5 – 12.47% around the active mining areas (Table 4A to

4E). It clearly shows that the mine voids are the major contributor of natural rainwater

harvesting locale and for water reservoirs. Therefore special care is needed to select

the open voids for filling up as it would reduce water sources.
