Marble
is used as one of the building stone in Rajasthan ,
which generates a lot of industrial and mining activity
in the state. The Rajasthan state is largest producer
of all kinds of marble in the country Makrana (Nagaur
District) is known for a very fine quality of white
marble deposit. The other area where marble is found
are Udaipur, Sirohi, Pali, Banswara, Dungarpur, Jaisalmer,
Bundi etc.
Occurrence
And Potentiality
Marble
deposits of the state can be broadly divided in four
groups (trade names).
- White
Marble
- Pink
Marble
- Green
Marble
- Other
Marble
White
Marble
White
marble is available in Makrana ( District Nagaur )
in huge quantity, which is often called Makrana stone
in laymen term. The marble deposit of Makrana is about
12 km. in length and 1.6 km. in length and 1.6 km.
in width. Well known deposits are found in Kumari,
Dungari, Bhermata Y Chancer area. The deposit of Chancer
area is considered to be the finest one and quarri3es
of this area have gone upto a considerable depath
of 15 to 60 meters. Now a days, because of deep mining
and other factors, mining in Makrana area has become
uneconomical. Further, good quality material has also
been exhauseted. Hence the need for developing new
areas where marble is available, close to surface
was felt. Soon in Rajnagar (Udaipur District) huge
deposit of white marble was discovered by the State
Department of Mines & Geology.
Although
marble deposit in Udaipur district are known since
long back when palaces and monuments in and around
Udaipur were built with local marble but in recent
years this district has received more attention and
mining activity in this district has developed rapidly.
In Udaipur district white marble is mainly available
in Rajnagar, Amet, Saprao, Marchana, Agaria, Parvati
etc.
Apart
from Udaipur district white marble in huge quantity
is also available in Tripura Sundri (District Banswara).
This marble is fine grained and has varities which
are pure white or that have pinkish or yellowish shades.
Some varities resemble to Italian Marble.
Pink
Marble
Babarmal
area of Udaipur district is the only main producer
of Pink Marble in the state. The area is situated
at 25 km South of Udaipur city on Jaisamand road.
This belt is about 5.20 km in length and 30 to 100
meters in width . This marble is some what hard, hence
require more time in cutting. Besides this, small
quantity of pinkish marble is also found in Makrana
and Abu Road area.
Green
Marble
Green
marble is found in keshriya ji about 60 km south of
Udaipur. There is great craze of this marble because
it has white jali with light or dark green base which
shines very good after polishing Block recovery is
very little as lot of cracks are found and hence it
is generally used for making chips and crazy. This
variety is actually serpentine rock but in trade it
is known as green marble.
Other
Marble
Others
types of marble are found in different parts of Rajasthan.
Yellow marble which actually shally lime stone and
takes good polish is available in Jaisalmer. Marble
deposits of Bhainsalana in Jaipur district is known
for its black strips. In Pali, Marble deposits exists
near Bar and Sendra. It is mainly pink coloured with
various shade and strips . Different types of marble
is also found in Ajmer, Jahazpur, Bundi. etc. but
the deposits are very small.
In
Rajasthan mining is mostly done by open cast method.
Only in Makrana at Chancer area underground mining
method has been adopted where it has been mines upto
100 meters depth but, the deposit is of spotless white
marble. Mining does not come under the head of industry
hence it is deprived of the benefits available to
an industry, Moreover, financing institutions are
also reluctant to finance the mines. Therefore, mechanised
mining is not developing rapidly. To increase the
marble production it becomes necessary to mechanise
the mine and minimise the use of explosives to reduce
the breakage so that it can cope-up with the increasing
demand of marble blocks by the diamond gang saw and
other conventional machines.
Marble
Based Industries
Marble
sawing and polishing industry of Rajasthan is one
of the most important mineral based industry.
Main
centre of this
industry is still Makrana.
There are
more than 1000 conventional sawing units and more
than 100 diamond gang saw are under operation. In
addition about 200 edge cutting and polishing units
are also working. They comprise both imported and indegenious machines. Among imported machines. Italian
machines out number those from Germany. A survey reveals
that the total installed capacity of sawing at Makrana
is about 5.00 lac tonnes per annum and the production
of blocks at Makrana is about 205 lac tonnes and about
2.00 lac tibbes us received from other areas for processing
like Rajnagar, Keshriya ji , Babarmal etc. Thus the
total raw material comes to 4.5 lac tonnes which is
short of the installed capacity.
The
Makrana area is almost saturated for the growth of
the marble industry
and therefore, in mining and processing
of marble Udaipur district is fast developing as the
second centre of marble based industry. Udaipur is
also well connected by Air, Rail and Road which also
contributes as major role to its fast developments.
In Udaipur about 20 conventional and 8 dimond gang
saw units are functioning Besides about 60 cutting,
polishing and tiling units are under operation. At
Rajnagar 14 diamond, 15 conventional and in in Chittorgarh
4 diamond and 12 conventional gang saw machines are
working. The total gross sawing capacity of Udaipur
district is more than 2 lac tonnes per annum. Total
production marble blocks is some where about 1.5 lac
tonnes which is much below the sawing capacity. Hence
there is acute need of mechanised and wide scale mining
of blocks so that it can copeup with the demand and
reduce the gap between demand and supply. Now a days
Rajasthan is exporting mirror polished marble tiles
in various sizes and thickness
The
chart given below depicts in brief the marble industry
right from the raw material to finished product and
from producer to consumer.
