On December
29,2016, Lalmatia mines of Eastern Coalfields Ltd. in Jharkhand,
there was a cave-in of an open cast mine. 23 workers were buried
, and their dead bodies were recovered. This is one of
the country’s worst mining disasters in recent times in terms of casualties as well as in terms of the size of the slide .The accident took place
when a mountain of earth formed by the overburden dug out in the open cast mine caved in .According to the
Director general of Mines safety(DGMS), the management of Eastern Coalfields
Ltd , despite the clear signs
like cracks developing and getting wider, did not remove workers and equipment out of bounds. This
is an example of how mining can be a disaster to human beings working there.
Minerals
are raw materials for a number of
important industries. They are non-renewable natural resources. The extraction
of minerals from nature is called mining. Mining often affects the environment
adversely. Therefore , mining has to be done
keeping into view the overall objectives of economic development and
environmental preservation .The mining sector in India employs more than one million workers. The main minerals produced in India are Iron
Ore , Bauxite , Chromite ,
Limestone , Coal and Copper ore.
Mining affects
environment in four ways:
1.Air
2.Water
3.Land
4.Health and Safety
Air: Surface mines
may produce dust from blasting
operations and haul roads. Many coal mines release Methane, a greenhouse gas.
Smelter operations with insufficient safeguards in place have the potential to pollute the air with heavy
metals , sulphur dioxide , and other pollutants.
Water: Mining throws Sulphide containing minerals in air
,where they oxidise and react with
water to form Sulphuric acid .This
impacts ground water , both from the surface and underground mines.
Land: The movement of rocks due to mining activities and overburden impacts land severely, as happened in
Jharkhand recently. These impacts may be temporary where the mining company returns the rock and the overburden to the pit from which they were extracted.
Health and Safety: Underground mining is hazarduous because of poor
ventilation and
visibility and the danger of rock falls
.The greatest health risks arise from
dust , which may lead to respiratory problems , and from exposure to radiation
, where applicable.
Since
1973, seven mining disasters have taken
place in India.In February 2001, 30 miners lost their lives in Bagdigi mines in Bihar .Every year , many mine workers lose
their lives in mining accidents in India
.Widespread illegal mining in government
and private mines accentuates the
problem.Mine sites which are no longer in use are also a major environmental
challenge.
The
historical and ongoing conflict
between mining and conserving environmental resources will continue to exist in future
as India’s forests, mineral bearing areas , major river watersheds,
tribal habitat regions and most backward
regions overlap significantly in the of Orissa , Chhattisgarh ,Jharkhand , Madhya
Pradesh , Maharashtra , Rajasthan .
Among
regulators in the sector,Indian Bureau of Mines(IBM) has the
mandate to play a proactive
role in minimising adverse impacts
of mining on the environment by undertaking environmental assessment studies on a regional basis.
Under the
environmental regulatory regime ,undertaking
mine level Environment Impact Assessment(IEA) and formulating management plans
(EMP) are mandatory for seeking
Environmental Clearance(EC).Under EIA Notification 2006, mining projects
that have a lease area more than 50ha in
size are classified under category A and
need EC from National Level
Environmental Impact Assessment
Authority , created with MOEF in Government of India. Mining projects that have
a lease area between 5ha to 50 ha are classified as Category B projects and require EC from SEIAA created
with respective Department of
Environment in the State Government. Mine leases smaller than 5ha in size
are not covered under the EC
process initiated by EIA Notification
,2006.Majority of mines that have lease
areas less than 5ha and do not fall
within the purview of EIA Notification ,
2006, though their data is not available , especially in the minor mineral
sector. Illegal mining that continues
unchecked also adds to the number of mines that operate without prior
environmental and social assessment
and appraisal by appropriate authorities.
The
following mining regulations provide for
environmental protection by integrating it as part of mining plans:
1.Mines and Minerals (Development and Regulation)Act , 1957.
Section 4A provides for powers to terminate lease holdings in case found detrimental to environment due to mine operations. Section
18 provides for ensuring environmental protection
along with mineral development.
2.Mineral Concession Rules 1960:Section 22(5) states that mining plan shall
incorporate environmental assessment and
management.
3.Mineral Conservation and Development Rules , 1988:Chapter
5 covers the environmental protection
issues comprehensively.
State Minor Mineral Concession Rules stipulate environmental protection
as basic and minimum
requirement for quarry license
issuance and operations.
Significantly
, the mining regulations cover all mines
that operate legally unlike
environmental regulations which do not
cover mines less than 5ha in size. However , lack of enforcement of mining sector regulations
have rendered the above provisions
in different mining regulations
ineffective and notional in terms of management of environmental and social impacts.
In Uttar Pradesh, unfortunately
, mining department is allegedly involved in encouraging illegal mining , so
much that High Court on July 28,2016
ordered for a CBI probe into
alleged illegal mining in the state,
including the role of government
officials in facilitating the same . The
case of suspension and subsequent
revocation of suspension of an IAS officer Durga Shakti Nagpal in September ,
2013 was also connected with her efforts to stop illegal mining .There was largescale illegal
sand mining in the Hindon and Yamuna river
banks in Gautam Buddh Nagar. This was
responsible for soil erosion and changing the natural flow of Hindon and Yamuna
which shifted its course by about
500 metres towards East and posed a threat to flood embankments in six sectors of Noida . This illegal sand
mining was due to high demand for sand
for increased construction activity. When officers led by Nagpal impounded vehicles and machinery used for
illegal mining , arrested illegal miners and lodged FIRs with police , she was
suspended and after reinstatement , was
shifted out of Gautam Buddha Nagar.
The above
is just an indication of how the mining department in one state has been encouraging illegal mining and
thereby , encouraging the destruction of
ecology and environment .The situation is similar in many other states where
illegal mining , encroachment of forest areas, underpayment of government
royalties, conflict with tribals regarding land rights are rampant , due to nexus of political ,
bureaucratic and mining mafia, playing havoc with the ecology and environment
.But there have been voices against such
operations from civil society , which
are growing louder and louder with time , as public awareness rises. The
department of Mines as well as Ministry of Environment and Forests , both at
the Centre and at the States level , have to act in a co-ordinated and determined manner to protect environment ,
ecology and human lives from mining.
