DIMENSION STONES

Dimension stone can be defined as natural rock material

quarried for the purpose of obtaining blocks or slabs that meet

specifications as to size (width, length, and thickness) and shape

(Barton, 1968, p. 4). Color, grain texture and pattern, and

surface finish of the stone are also normal requirements.

Durability (essentially based on mineral composition and

hardness and past performance), strength, and the ability of the

stone to take a polish are other important selection criteria.

method of finishing a stone, and the type of finish applied

(Stone World, 2001, p. 106-139).

India has a long history of utilisation of stones. Towering templesacquisitive carvings, huge imposing palaces, monumentsmusoleums, minarets, gates and artefacts speaks volumes abouthe use of stones, let it be the Khajuraho, Delwara temples, cavesof Ajanta & Ellora, stupas of Sanchi, Konarktemple, BulandDarwaza of Fatehpur Sikri, Victory Tower ofChittorgarh, Forts oRajasthan, U.P and Delhi all have been built using one stone oother.

The Taj Mahal, beauty par excellence built in 17th

century byEmperor Shahjahan in memory of his beloved wife MumtazMahal has been built using white marble from Makrana areaNagaur Distt. of Rajasthan.

Although Delwara temple at Mount Abu, built earlier than

Taj Mahal could not give impetus to marble industry as the Tahad given. It has remained the trademark of India for the lasthree hundred years.

MARBLE

The term marble is derived from the Latin word MURMUR which itselfcame from Greek root Marmorous meaning ShiningStone.

Murmur in Persian means White and Sang means stone hence

Sange-murmur

Geological definition: A metamorphosed limestone produced byrecrystallisation under condition of thermal and also regionalmetamorphism.

In commercial parlance almost any rock which can take polish easilymore especially unmetamorphosed lime stones are termed as marble.

Marble definition (USGS):Commercial marble includes metamorphosedlime stones and serpentine rocks, all of which are capable of taking apolish. An important member of this classification is serpentine marble,which is also known as Verde antique, and comprises green-to-black

serpentine, which is a hydrous magnesium silicate mineral that iscrisscrossed by veins of lighter minerals, such as calcite or dolomite.


10/88

Why is marble so beautiful?

It is largely consisting of calcite, whose boundaries are fused.

This has the ability to transmit lights to a depth of 12.7 to 38

millimeters from where it is reflected by the surfaces of deeper

lying crystals which gives a pleasing and cool look. Your eyes

will never tire off looking at marble.

Indian Classification of Marble BIS : 1130-1969 (reaffirmed in October 1998) for marble blocks, slabs and tiles to be utilised

dimension stone has classified marbles into 25 different categories comprising 7 categounder a broad group ofwhite marbles and 18 categories under a group ofcoloured marblesnew varieties are also in the trade

The important new types not included in BIS classification are:

1) Yellow marble of Jaisalmer

2) Pista marble (amphibolite variety) of Andhi-Jhiri belt, Jaipur, Alwar and Daudistricts, Rajasthan

3)Brown green and golden ultramafics of Dunkar, Churu district, Rajasthan 4) Chocolate-brown and English teak wood marble of Jodhpur district, Rajasthan

5) Parrot green marble of Jhilo in Sikar district, Rajasthan

6)Chocolate-brown or wood finish marble of Mandaldeh, Chittaurgarh district, Rajasth 7) Purple marble of Tripura Sundari in Banswara district, Rajasthan

8) Blue marble of Desuri in Pali district, Rajasthan


13/88

International Classification of marbleGroup ASound marbles with uniform and favourable working qualities containing no geological flaws

or voids.

Group BMarbles similar in character to the preceding group, but less favourable working qualities

may have natural faults such as hairline cracks, voids and inclusions, a limited amountof wasting, sticking and filling may be required.

Group CMarbles with some variation in working qualities, geological flaws, voids, veins and lines of

separation are common. It is standard practice to repair these variations by one or more

of several methods - wasting, sticking, filling or cementing. Liners and other forms ofreinforcement are used when necessary.

Group DMarbles similar to Group C but containing a larger proportion of natural faults such as cracks,

voids, discolouration, maximum variations in working qualities and requiring more of thesame methods of finishing. This group comprises many of the highly coloured marblessignificant for their decorative values.The soundness classifications merely indicate what method and amount of repair andfabrication is necessary prior or during installation, as based on standard tradepractices.

Resources of Marble

Geological distribution:

Dharwar System:

The marble belonging to Dharwar System is mostly distributed in Aravali and Raialo Series ofRajasthan, Champaner Series of Gujarat, Sakoli Series of Madhya Pradesh and Chilpi Series

of Maharashtra.

Cuddapah and Delhi SystemsMarble deposits of Cuddapah System are located in the Papaghani Series of Andhra Pradesh,

Bijawar series of Madhya Pradesh and Kaladgi Series of Karnataka. Delhi System marbles

are located in Alwar Series and Ajabgarh Series of Rajasthan. Marbles of Ajabgarh Series are

exposed around Jaipur Bharatpur, Kishangarh, Ajmer, Mewar, Udaipur and Sirohi areas of

Rajasthan; Danta and Palanpur area of Gujarat; and Narnaul area of Haryana.Vindhyan SystemIt is mostly found in Morena district of Madhya Pradesh, and Guntur & Kurnool districts of Andhra

Pradesh. Bhima Series are developed in Bijapur and Gulburga districts of Karnataka. Marble

belonging to Vindhyan System is of creamy, grey, bluish and buff in colours and is capable of

taking a good polish.

Jurassic SystemFossiliferous limestones of Jurassic System occurring in Jaisalmer and Bikaner districts of

Rajasthan take very good polish.Cretaceous SystemCoraline limestone belonging to Bagh Beds of Upper Cretaceous age furnish a very handsome

marble capable of taking a good polish and are located at Kherwan, Chirakhan and Bowarle in

Dhar district of Madhya Pradesh.

Mining of marble

marble mines are semi-mechanised and few are fullymechanised

preferred mining method is 'Bench-Quarrying'

mining machineries like line drillers, chain saws, belt

saws, diamond wire saw cutters, derrick cranes,loaders and tippers are used

ultimate product in marble mining is parallelepipedregular blocks, luffers and khandas

Fully mechanised mines recover about 35% regularblocks, 30% luffers and 30% khandas

UNDEGROUND MINING OF MARBLE


44/88

UNDEGROUND MINING OF MARBLE

Not practiced in India.

Italy is fore runner owing to its Geology.

Adopted where open pit mining is unfriendly to

Environment.

Overburden is difficult or un-economic to move. Overburden is entirely non-productive.

Rock quality is sound to sustain load.

The quality and Quantity of marble is proved bydrilling.

ADVANTAGES & DISADVANTAGES OFUNDERGROUND MINING


45/88

UNDERGROUND MINING

Advantages

Less destruction to environment. No generation of dust. No or less pollution. No effects on surroundings.

Disadvantages Cost intensive. Contamination of ground water. Not suitable for selective mining.

Costly product.
