Site Analysis
Location and Connectivity: Mine is located 1.19 km from Lumshnong village connected by NH-
44 at 0.39 km NE. Bihara Rail way Station is 35.46 km SE.
Land use and Land ownership: Land of the mine lease area is a private land which has been
acquired. It is an existing mine.
Topography of the area: The topography of the area is hilly terrain. The ground surface shows
rough and rolling topography, with elevation difference of28m from 524 m RL to 496 m RL.
Drainage Pattern: There is no water body in the ML area. A river named Wah Lukha and Lubha
river are the main river in the area, Wah-lukha flows at about 4.83 Km NEE and Lubha river
flows 3.53 km SE from the lease boundary. The general slope of the area is towards South East.

Local Geology: The limestone formation occurring over the applied area belongs to the lower
Lakadong limestone unit of Sylhet formation of Jaintia Group. The base of this limestone unit
lies conformably over the Therria Sandstone. The Lakadong Sandstone is underlain conformably
by Lakadong Limestone inter bedded with sandstone to the further south of the area.
Exploration Undertaken: Exploratory four boreholes up to average depth of 37.5 m were
drilled during the year 2001 before the execution of lease. During the year 2011, 3 DTH holes
were drilled up to depth of 20m each. Five DTH holes were drilled at the site in the year 2014-
2015.

boundary is 12.50 km SE from the mine area.
Existing Infrastructure:
The area is connected with all season motor road. The nearby villages are electrified, though
mining operations will not need electricity. The main source of water is water tankers from
cement plant.
Soil classification:
Soil consists of yellowish brown silty clay mixed with boulders of sandstone and yellowish
brown, medium to fine grained, weathered and fractured with brown stain.
Climatic data from secondary sources:
The climate of the district is directly controlled by the southwest monsoon originating from the
Bay of Bengal and the Arabian Sea. The climate shows a variation from the warm, humid
tropical in the plains in the eastern and southern part and temperate climate is experienced in
the western part around the district headquarter Jowai. The climatic conditions vary
substantially from place to place due to wide differences in altitude. The average annual rainfall
in the district is 4173 mm recorded at Rymphum seed farm in Jowai. The district receives a
fairly high rainfall throughout the year. Most of the precipitation occurs between April and
October.(Source: CGWB report)
Social Infrastructure available:

assured.
Analysis of proposal (Final Recommendations)
The project is proposed to mine 179943TPA limestone mineral in an area of 4.20 ha. which will
be supplied to cement plant "Barak Valley Cement Limited". The direct employment about 47
workers besides indirect employment. Most of the employment is given to locals. Interest of
the schedule tribes especially the weaker section of the committee shall be ensured. Low cost
of production and high demand and remunerative price will make the project viable.
