2.0 INTRODUCTION OF THE PROJECT/ BACKGROUND INFORMATION
2.1 IDENTIFICATION OF PROJECT AND PROJECT PROPONENT
Dharampur Limestone mining lease, measuring 40.47 hectares (ha.), is
a captive mine of Saukem, and is in survey no. 2/9 part, of Dharampur
village in Ranavav Taluka of Porbandar district, Gujarat. The Mining
lease was granted for 20 years w.e.f. 24.12.1959 there after renewed
for a period of 20 years w.e.f. 24.12.1979. Application for 2nd renewal
of mining lease for another 20 years was submitted to the Govt. of
Gujarat, before one year of expiry (07/12/1998) of lease and is
under consideration by the State Govt. (Annexure-1).
M/s Saurashtra Chemicals Limited is manufacturing Soda Ash in its
works at Porbandar. The entire limestone production from the mine is
proposed for the manufacture of Soda Ash. No part of the product is
proposed to be sold to any other party.
Looking to the capacity of the Soda ash plant of 0.65 Million Tonnes per
year, the requirement of chemical grade limestone is 1.3 Million Tonnes.
Only part of the requirement i.e. 0.20 Million Tonnes is proposed to be
met from this mine.
2.2 BRIEF INFORMATION ABOUT THE PROJECT
The project has been proposed for an annual production of 0.20 Million
Tonne Per Annum (after expansion) of limestone chemical grade by
open cast method. The lease area is government waste land. No forest
land is involved. The estimated net Geological Reserves is 1.72 million
tonne & 1.53 of limestone mineable reserves and proposed expansion
from 40,000 Metric tones to 2,00,000 Metric tonnes.
As has been stated earlier, there will be no O/B and there will
also not be any generation of rejects as a result of the mining
operations.
As stated earlier the area which is mineralized is generally devoid of
any soil. However, if any soil is encountered, it will be removed
separately and will be utilized for tree plantation program.
As there will be no waste generation at this mine, no backfilling will be
feasible. Hence, lower portion of the mined out area shall be used for
rainwater storage. For this purpose, all necessary precaution shall be
taken as per Reg. 115(1) of MMR 1961 to isolate and safeguard against
the inadvertent entry to worked out pit area, Sides of rainwater
storage/ voids shall be given adequate slope of about 45°. Masonry

stone retaining wall/stone pitch wall will be constructed to give support
the sides, if required. Prior to abandonment of working, a protective
barbed fencing shall be laid around the periphery of the pit to check
the inadvertent entry of men and animals. So that it can be gainful
post mining use to society. Regular water analysis shall be carried out.
2.3 NEED FOR THE PROJECT AND ITS IMPORTANCE TO THE COUNTRY OR
REGION
Lime stone is very important chemical mineral and is the principal raw
material for the production of soda ash and clinker for cement etc. The
need for mining of the chemical grade limestone from the project
(mine lease area) has arisen to meet the current situation of demand
supply gap faced by company ,
Limestone Mining is a very important economic activity in Saurashtra
region of Gujarat. Chemical Grade Limestone is mainly found in this
region. This high purity limestone is essential for soda ash
manufacturing. For soda ash industry to remain competitive, availability
of chemical grade lime stone in nearby area is extremely important.
The Soda Ash based limestone mining industry contributes significantly
to the State Gross Domestic Product and provides direct employment
to nearby laborers. Additional jobs are created by way of
transportation and related jobs, ancillary to mining. Subject mine lease
aims to augment the limestone supply to SAUKEM, Porbandar.
The products of SAUKEM’s Soda Ash Plant, Porbandar, especially soda
ash, are a vital input for a number of basic industries such as glass, pulp
and paper, chemicals and detergents, besides others. Consequently,
this project aims at keeping many of the key industries within the
country well supplied with an essential raw material.
2.4 DEMAND-SUPPLY GAP
the capacity of the Soda ash plant of 0.65 Million Tonnes per year, the
requirement of chemical grade limestone is 1.3 Million Tonnes. Only
part of the requirement i.e. 0.20 Million Tonnes is proposed to be met
from this mine.
At present, the company’s annual requirement for chemical grade
limestone is about 1.30 million tones (Sized), part of which, are sourced
from captive mines and the balance from domestic and overseas
merchants. The gap between the annual demand and the quantity of
sized limestone received from captive mines is substantial and thus the
company intends to bridge this gap by winning limestone from the
proposed project.

3.4 PROJECT DESCRIPTION WITH PROCESS DETAILS
3.4.1 Method of Mining & Blasting
Taking into consideration shape and nature of deposit and the
targeted production the mine will be worked by manual opencast
method of mining. Attempts have been made to design & exploit the
deposit with minimum damage to environment & optimal utilization
of limestone for Soda Ash manufacture. Chemical grade limestone
occurring as compact layer, will be worked in one bench of height not
exceeding 3.0 mtr. The drilling will be done with the help of 65 / 110 mm
dia. down the hole drills (Drifter). The blasting will be done mainly with
ANFO as the column charge and Slurry explosive as the base charge.
The sizing (25- 100 mm) of chemical grade limestone will be done
manually at mine site and loading of sized limestone will be done
manually by labours in to trucks & transported to Soda Ash Plant.
Mining operations will be carried out by manual opencast method with
drilling and blasting and the same will be continued in future also.
Benches shall be restricted 3.0 mts. To the extent possible, benches shall
be advanced along the strike. The direction may be varied in due
course based on experience gained, to give wider benches, longer
faces and proper alignment along haul roads/ ramps
The mining lease covers an area of 40.47 hectares. The mineralized
area is delineated to whole of the area and mines workings shall be
restricted in 36.52 hectares till end of mine life.
Multi location working will be proposed in the forthcoming years. A strip
of 7.5 mts of statutory barrier along mining lease boundary will be
designated as “No-mining Zone”.
The details about storage and transport of explosive are given below:-
PROJECT: DHARAMPUR LIME STONE MINE (40.47 Ha) PRE-FEASIBILITY REPORT APPLICANT: M/s SAURASHTRA CHEMICALS LTD.
PFR-DHARAMPUR-9
Type of Explosives used
Various types of explosives such as ANFO, slurry, emulsion etc. will be
used for blasting. Since ANFO is cheaper and economical, it will be
used as much as possible except in rainy season. Delay detonators or
Nonel detonating fuse will be used since multi row system of firing will
be carried out so as to reduce the ground vibration, noise, fly rock etc.
due to blasting. Sequential blasting techniques using sequential
blasting machine shall be used to reduce explosive charge per delay
to a minimum to reduce ground vibration.
The details about storage and transport of explosive are given below:-
Storage of Explosives
Company’s centralized magazine is situated near Dharampur –
Kajawadri village, 15 kms from the mine. The total capacity of the
magazine is 4500 kg of class 2 explosive, 30000 detonators, 40000 mts of
detonating fuse and, 10000 mts of safety fuse approved by Petroleum
& Explosive Safety Organization (PSPO). The explosive from the
magazine to the mine shall be transported using licensed explosive
van. At present the capacity of the magazine is considered adequate
hence no additional magazine is proposed.
Precautionary Measures
Adequate precautionary measures will be taken as given below:
(a) Adequate siren system will be in operation.
(b) Legible warning sign in the language understood by the local
people.
(c) Enough security guards, especially posted on roads etc.
(d) Before blasting the upper surface of the bench shall be cleaned off
any stones lying above, as it is a major source of flying stones.
(e) The trunk line of the detonating cord shall be covered with sand to
reduce air over pressure, as it is major source of air blast noise.
(f) Controlled blasting shall be practiced and only between 12 Noon
and 2PM.
(g) All safety measures as prescribed under MMR 1961 and circulars
issued by DGMS.
(h) An effective record of instruction to guards given for working and
clearance shall be maintained.
Transport of Explosives
Transportation of explosives will be done by an “explosive van
(Potable)” approved by PSPO.

6.0 PLANNING BRIEF
6.1 PLANNING CONCEPT
Open cast Semi-mechanized mining method will be adopted for
limestone mining. Project will produce Limestone @ 0.20 MILLION
METRIC TONNE PER ANNUM, which will be used as raw material for
production of soda ash in Porbandar Soda Ash plant of Saukem.
The mining plan was approved under rule 11 of MCDR 1988 by
Regional Controller Of Mines, IBM, Udaipur vide their letter no.
682(23)553/95-MCCM(N)UDP dated 11.06.96 for period 1996 –97 to 2000
–2001, thereafter Scheme of Mining was approved for period 2002-03
to 2006-07 by Regional Controller of Mines, IBM, Udaipur vide there
letter no. 682(23)MS-161/2002 MCCM(N) UDP dated 09/04/2003.
The last Scheme of Mining including Progressive Mine Closure Plan in
respect of Dharampur Limestone Mines (40.47 Hectares) submitted
under Rule 12 of MCDR, 1988 was accorded approval vide IBM letter
No. 682 (23) M.S. 387/2007- MCCM(N)-UDP dated 18.09.2007 for 40,000
tones/ annum limestone (ROM).
The Dharampur Limestone Mine got Environmental Clearance from
MoEF, New Delhi vide Letter No. 11015/1223/2007-IA-II(M) dated
30/09/2009 for production capacity of 40,000 TPA of chemical grade
Limestone.
The scheme of mining for ensuing five years was submitted for 2,00,000
tones/ annum sized limestone for approval to IBM, Udaipur and same
has been approved vide letter no. 682 (23) (384)/2007- MCCM(N)-UDP
dated 19.11.2012.
Now keeping in view the gap between the annual demand and the
quantity of RoM/Sized received from captive mines is substantial and
thus the company intends to bridge this gap by winning limestone from
the proposed project. The production (ROM/Sized) targets of limestone
will be 0.20 Million metric tonnes per annum.
