As per the technical report from the Department of Mines & Geology the proposed

area has enormous amount of economically viable building stone deposits and

therefore not fit for agricultural purpose.

ii. Brief Description of nature of project

The proposed quarry area is spread across over an area of 4.00 acres. The area is

abundant in building stone. The building stone shall be extracted by open cast with

semi mechanized method and processed further to produce final product suitable for

construction and building purpose.

iii. Need for the project and its importance to the country and or region

The Indian real estate sector has witnessed high growth in recent times with the rise for

office and residential spaces. The major need of building stone is due to its high

compressive strength and durability (among the hardest, dimensional & structural

stones) it can effectively withstand the vagaries of nature. Fine-grained granite is

employed for ornamental and monumental work as well as for inscription purposes.

The mineral-rich colours, and the hardness & density, makes it useful for many

applications. Polished slabs and tiles are used in countertops, flooring, retaining walls

and landscaping around a centre fountain/pond, staircase and many other design

elements (residential and commercial applications). It is also known as the

maintenance-free stone. The proposed mining project will full fill its end uses in

buildings and construction, bridges, paving, monuments and many other exterior

projects. The mining and associated activities in the mineral bearing areas bring about

gains in gross domestic product, i.e. there is though a minor contribution by the

proposed project but will add to the gains in G.D.P. (Gross Domestic Product).

iv. Demand and Supply Gap

The demand of building stone is huge and it is a continuous process.

v. Imports vs. Indigenous production

The demand for building stone is in only domestic market since it is a locally produced

product.

vi. Export Possibility

Since the building stone is a locally produced product there is no possibility of

exporting.

vii. Domestic and Export Markets

There is a continuous demand for building stone in the domestic market for all the

developmental & infrastructural projects.

v. Project description with process details (a schematic diagram/flow chart showing the

project layout, components of the project etc. should be given).

The said quarry of building stone would be extracted by open cast method by manually

and semi mechanised method by using air compressor operated jack hammer drills,

excavators, truck dumpers etc. Since the rocks and reserves are exposed, the open cast

quarrying is sufficient enough to extract the deposits. Further continuous development

and production will be ensured till the deposits exhaust. The flow chart of the project is

as follows:

vi. Raw material required along with estimated quantity, likely source, marketing area of

final product/s , mode of transport of raw material and finished product and Finished

Product

The said project is not manufacturing any product as such. The project’s process itself is

involved in extracting raw material i.e., rock from the earth and process further into

desired size of jelly stone. The raw material from the site to the processing plant would

be transported via trucks and Lorries. The finished products from the outlet to

customers would be transported in suitable vehicles based on the quantity. The

finished product will be sold out in domestic market.

vii. Resource Optimization/recycling and reuse envisaged in the project, if any, should be

briefly outlined.

The said quarry area is a hillock and the top soil generated during the process of

quarrying is very minimal. However, topsoil excavated from the quarry will be dumped

separately at pre-determined place and subsequently will be utilized in spreading over

reclaimed areas for plantation.

About 5% of the reserves are considered as waste. The waste rock mainly consists of

weathered rock and intercalated wastes which are non-toxic in nature. The 60% of

waste will be used for retention wall, agriculture, roads etc., and the 40% of waste will

be transported to dump yard designated for the purpose. Therefore, the waste dump

area identified is sufficient to accommodate the dump in a phase wise manner.

viii. Availability of water, energy sources/ power requirement and source should be given.

The water is used for the domestic purpose and for the suppression of dust particles

generated by transportation of raw material on haul roads. There are borewells in the

neighbouring site from which the water will be sourced for said purposes. For the

operation of Air Compressors DG sets will be utilized.

The total water requirement is as follows:

Table 2 Water Consumption

Sl.no Particulars Quantity in KLD

1. Domestic Purpose 2.8

2. Dust Suppression 4.0

TOTAL 6.8

ix. Quantity of waste to be generated (Liquid & Solid)

As such there will be no liquid waste generated from the entire process apart from

sewage waste generated from the office which is about 2.24 KLD and the solid waste

generated from the process would be only the weathered material of granitic gneisses

and its associated rocks with secondary intrusive. Weathered and highly fragmented

rock is also considered as waste along with chipped out remains of building stone

formed due to the quarrying process which will be utilised for back filling of the pit

7

formed due to quarrying and also can be used as aggregates in road and building

constructions.

4. Site Analysis

i. Connectivity

The said quarry area is very well connected to roads and railways. The distance from

the site to NH-17 is about 11 Kms.

The distance from the site to Gokarna Road Railway station is about 8 Kms.

The Distance from the site to Mangalore airport is about 160 Kms.

ii. Land form, Land use and Land Ownership

The said quarry land is a private land. Due to the presence of abundant rock material

just 1-3 m below from the top soil the said land is not suitable for agricultural purpose.

The private land belongs to M/s. Hirehosba Stone Crusher with the Sy.No. 346/2, 3 of

Hanehalli Village, Kumta Taluk and Uttara Kannada District, Karnataka.

iii. Topography (along with map).

The area identified is highly undulating terrain surrounded by rolling pediment and

pediplain shallow. In this terrain, Granitic gneiss is the basement rock formation above

which, grey granite is over lined with various dimensions horizontally and vertically.

The litho unit is partially exposed as well as hidden type in the identified area and the

trend of the formation is North 18⁰ West to South 18⁰ East. The highest ground level of

the area is around 85 m above mean sea level as per the GPS readings and also

Toposheet No. 48J/06. The quarry area is well connected by metalled and asphalted

roads.

iv. Existing land use pattern (agriculture, non-agriculture, forest, water bodies (including

area under CRZ), shortest distances from the periphery of the project to periphery of the

forests, national park, wildlife sanctuary, eco sensitive areas, water bodies (distance from

the HFL of the river), CRZ. In case of the notified industrial area, a copy the Gazette

The Proposed area is a non-agricultural land and there are no forests, national parks,

wildlife sanctuary, eco sensitive areas, water bodies, CRZ within the radius of 5 km from

the periphery of the proposed quarry site area.

v. Existing Infrastructure

The construction of site services like site office, workers shelter, site workshop, store

room and first aid counter will be constructed in the non- mineable area. Drinking

water facility will be made available for the labourers.

The post office is situated from the quarry site at a distance of 3.5Km at Gokarna

village and the power line passes at a distance of 60m from the identified quarry site.

The nearest railway station is at Ankola, which is located about 30Km north-west of the

site. The nearest port identified is Karwar at a distance of 58 Km from the site.

vi. Soil Classification

The area is covered by thick lateritic soil derived from chemical weathering of

basement rock granitic gneiss as well as over lined granitic formation. Pegmatite veins

are observed at the elevated portions and are identified as thin linear patches

embedded within the gneisses and granites. Grey granites are identified in the form of

younger rock types at shallow depths and are exposed rarely in the vicinity with

differential elevations.

The area is covered by thick layer of lateritic soil derived from chemical weathering of

granites and gneisses. The soil sometime looks like yellowish sandy and loamy and is to

medium grained in nature. The maximum thickness of the soil noticed in the area is

around 2.5 m at slopes.

These are the acidic intrusions embedded within the crevices of granitic gneiss and

granites. Thin intrusions of pegmatite veins were noticed in rock cut areas and are

white in colour due to enrichment of orthoclase minerals. The intrusions are seen

sporadically at deeper levels.

Granites occur in the form of exposure in and around the identified area and are grey

in colour with fine grain size. Granites are locally identified as building stones with

varying thickness and extended NNW to SSE in direction, cutting across the basement

rock granitic gneisses. The deposits run over a length of about 200 m with varied

thickness.

The study area is underlined by granitic gneisses, having strike direction NNW to SSE

and dipping towards south to south-east with 68⁰ to 70⁰ slope. The foliation and

lineation can significantly be seen in the gneisses with uniform mineral assemblage.
