Basantpur-Tapin Washery (4.0 MTY) EIA_EMP I-1

CHAPTER -1

INTRODUCTION

1.0 GENERAL

The coal seams in mines under Central Coalfields Limited have been found to have coking propensities to different extent and it has been found by scientific investigation that production of high valued coking coal can be produced by washing this coal. Coal is an important infra-structural input and a dominant source of energy in India accounting for 55% of the country’s primary energy needs. The quality of coal plays an important role in environmental aspects during its use especially in power plants. Due to drift origin of Indian coal, ash content is quite high and coal seams have dirt bands of carbonaceous nature. High ash content in coal causes environmental pollution apart from reducing plant efficiency and adding the cost of coal transportation per unit calorific value. Further ash disposal is itself a difficult task with adverse environmental impacts.

1.1 BRIEF DESCRIPTION OF THE PROJECT CCL intends to set up a coking coal washery with raw coal linkage.It has been proposed to transport the raw coal from Tapin South OC, Tapin North OC, Parej East OC, Jharkhand OC, Kedla OC and Kedla UG to Basantpur Tapin Coking Coal Washery by the existing road.The raw coal throughput of the washery will be 4.0 MTPA on ‘adb’ (air dried basis) and likely to vary within the range of 31.7 to 35.2% on ‘adb’. The washery will be designed to produce three products viz. washed/ clean coal, washed coal (power) & rejects.

1.2 PURPOSE OF THE REPORT

The purpose of the EIA/EMP Report is to ensure compliances of environmental norms in operation of the proposed Basantpur-Tapin Coal Washery with raw coal capacity of 4.0 MTPA and to seek Environmental Clearance from Ministry of Environment, Forests & Climate Change, Govt. of India, in view of EIA Notification, 2006 dated 14th September ’06. The proposal of terms of reference (TOR) was discussed in 40th EAC meeting held on 26th October, 2018. Subsequently the Ministry of Environment, Forest & Climate Change, Govt. of

India, (MOEFCC) issued TOR vide letter No. J-11015/97/2018-IA (M) dated 07-01-2019 for obtaining Environmental Clearance for the proposed Basantpur-Tapin Coal Washery of CCL. CCL has engaged CMPDI, consultant of all CIL companies to undertake Environmental Impact Assessment studies. The report envisages the assessment of the impact of various environmental components and its mitigation measures in order to minimize the adverse impacts

PROJECT DESCRIPTION

2.0 GENERAL

The proposed Basantpur-Tapin Coal Washery will be a three product

washery to be operated.

A three-product coking coal washery producing washed/ clean coal,

washed coal (power) & rejects has been conceptualized. Clean coal at 18%

ash for supply to steel plants for metallurgical purpose has been considered

and washed coal (power) at 34% ash will be sent to thermal power stations.

2.1 DESCRIPTION OF THE PROJECT

2.1.1 Name of the Project

Basantpur-Tapin Coal Washery (4.0 MPTA).

2.1.2 Type and Need of the Project

Basantpur Tapin Coking Coal Washery is a new proposed project using Jig/HM Separation/Spiral/Flotation technologies or combination thereof. It is a three product washery and the Clean Coal Technologies used in washery shall act as a safeguard against Environment Pollution. Need of the project-

Central Coalfields Limited is facing increasing demand of coal because of increased demand from industry and power sector. Continuing and augmentation of coal production from the mines of CCL will help to bridge the gap of demand and supply of coal in India. Therefore, with commissioning of new washeries, Coking coal supply to steel & Power sector will improve.

Expeditious execution of washery projects will save our FOREX Reserves & thereby, strengthen our economy.

2.1.3 Objectives

Basantpur-Tapin Coking Coal washery of 4.0 MTY capacity will supply

washed coal with 33.5+0.5% ash to thermal power stations.

2.1.4 Life of the Project The economic life of the washery has been considered as 18 years.

2.6 PROCESS FLOW & BALANCE OF PRODUCTS

2.6.1 Unit Operations

• Coal Washing Methods

The various procedures are broadly classified as the ‘Wet’ ‘and Dry’ processes. The

dry process doesn’t involve the use of water, where as in the wet process, the water

is the main medium for washing and jigging. The washery will be operated on wet

process. The different processes involved in the washery are given below;


Crushing

Purpose of the crushing is to reduce the Run of Mine (ROM) coal to a size suitable

for washing and, size reduction involving various principles such as compression,

impact, shearing, splitting and attrition.

Primary crusher(s) are generally designed to receive ROM coal and reduce it to a

top size of 2” to 8’’

Secondary crushers are generally designed to reduce the size (to a top size of 1 ¾”)

of the middling fraction from jigs or the middling fraction from heavy – medium trough

separators, and, in turn these fractions would be rewashed. Crushing of as received

coal sample (rom coal size) down to -13mm size is proposed.

Screening

Sizing is the separation of a heterogeneous mixture of particle sizes into groups

wherein all particles range between a maximum and minimum size.

Screens Used in Coal Preparation:

1. Scalping screen – for separating refuse and fines prior to size reduction

2. Raw coal sizing screen- for separating the raw coal into coarse and fine size

for further processing.

3. Pre-wet screen- to remove fines prior to the mechanical cleaning

4. Heavy media recovery screens- for recovery and reuse of magnetite

5. Desliming screens-to remove extreme fines; and

6. Dewatering screens-to remove water.

Jigs

Jigs operate by differences in specific gravity and rely on stratification in a bed of

coal when the carrying water is pulsed. The shale tends to sink, and the cleaner coal

rises. The basic jig is suitable for larger feed sizes. Although the Baum jig can clean

a wide range of coal sizes, it is most effective at 10-35 mm. A modification of the

Baum jig is the Batac jig, which is used for cleaning fine coals. The coal is stratified

by bubbling air directly through the coal-water-refuse mixture in this cleaning unit.

For intermediate sizes the same principles are applied, although the pulsing may be

from the side or from under the bed. In addition, a bed or hard dense mineral is used

to enhance the stratification and prevent remixing. The mineral is usually feldspar,

consisting of lumps of silicates of about 60mm size.

Jigs offer cost effective technology with a clean coal yield of 75-85% at about 34%

ash content. The jigs are used more frequently than dense-medium vessels because

of their larger capacities and cheaper costs.


Baum Jig and Fledspar Jig

Dense Media Seperator

Dense-medium vessels also operate by specific gravity difference; however rather

than using water as the separation medium, a suspension of magnetite and water is

used. This suspension has a specific gravity between that of coal and the refuse and

a better separation can be obtained. The slurry of fine magnetite in water can

achieve relative densities up to about 1.8. Different types of vessels are used for

dense-medium separators such as baths, cyclones and cylindrical centrifugal

separators. For larger particle sizes, various kinds of baths are used, but these

require a substantial quantity of dense- medium, and therefore of magnetite. For

smaller sizes, cyclones are used where the residence time is short and throughput

relatively high. Cylindrical centrifugal separators are used for coarse and

intermediate coal.

Dense-medium cyclones clean coal by accelerating the dense-medium, coal and

refuse by centrifugal force. The coal exits the cyclones from the top and the refuse

from the bottom. Better separation of smaller-sized coals can be achieved by this

method.

Key factors in the operation of any dense-medium system based on magnetite are

the control equipment and the efficiency of magnetic recovery for recycle.

Dense Media Separator

Froth Flotation

Froth flotation is the most widely used method for cleaning fines. Froth flotation cells

utilize the difference in surface characteristics of coal and refuse to clean ultra fine


coal. The coal-water mixture is conditioned with chemical reagents so that air

bubbles will adhere only to the coal and float it to the top, while the refuse particles

sink. Air is bubble dup through the slurry in the cell and clean coal is collected in the

froth that forms the top.

Froth Flotation

Transportation of rejects to Temporary Reject Storage Site by belt conveyor. Provision of closed water circuit with zero effluent discharge has been envisaged.

2.6.3 PROJECTED BALANCE OF PRODUCTS

3.2.1 Study Area for Air Environment

For the proposed project, the project area has been taken as the core zone and the

area within a radius of 10 km of the core zone has been taken as the buffer zone.

3.2.2 Meteorology

The meteorological data recorded during the monitoring period is very useful for

proper interpretation of the baseline information as well as input for air quality

prediction. Historical data on meteorological parameters also plays an important

role in identifying the general meteorological regime of the region.

The year may broadly be divided into four seasons:

• Winter season : December to February

• Summer season : March to May

• Monsoon season : June to September

Post-monsoon season : October to November

On-site monitoring was carried out by M/s. Go Green Mechanisms Pvt. Ltd. Data

of micrometeorological and microclimatic parameters were recorded by installing

a meteorological station on the terrace of “Basantpur - (South West) of Basantpur

– Tapin Coking Coal Washery” & micrometeorological parameters like Ambient

Temperature, Relative Humidity, Wind direction, Wind Speed, Rain fall &

Barometric Pressure, etc were recorded on hourly basis during the study period.

A 3 Cup anemometer was used to record wind speed and Hall Effect (Wind

Vane) was used for wind direction continuously during the study period. Ambient

temperature was recorded by using Digital sensor. Relative humidity was

measured by using hygrometer. An aneroid barometer was used for measuring

atmospheric pressure and a self-recording rain gauge was used for rainfall data

collection. Cloud cover data was collected by visual inspection.

During the study period, hourly reading of wind velocity, wind direction,

temperature, relative humidity, cloud cover and rainfall data were recorded and

reported.
