Coal mining

Overview

EMIL, the mining arm of the Aditya Birla Group, is in mining business since 1950 operating iron ore mines in the Barbil region of Orissa. To garner the experience gathered in iron ore mining, EMIL has decided to diversify in to other minerals like coal etc.

However due to policy restriction, coal for merchant mining is not allowed to private sector in India and the only available route to enter into the sector was through the mine developer cum operator (MDO) route. The MDO contractor carries out entire gamut of activities right from land acquisition, R&R, mine planning to development and operation of mine and coal extraction and coal transportation up to the owner's loading silo on behalf of mine owner who holds the mining lease. In return, the mine owner pays a contractually agreed fixed mining fee on per tonne of coal and/or per cum of over burden (OB) basis to MDO. Large sizes heavy earth moving machinery (HEMM) are deployed to achieve economies of scale. Focus is more on achieving higher levels of equipment availability through Maintenance and Annual Repair Contracts (MARC) given to reputed vendors.

EMIL is the largest mine-developer-cum-operator (MDO) in the private sector in India. EMIL currently operates two projects — Bhubaneswari Coal Mine & Rajmahal Coal Mine, through its subsidiaries Bhubaneswari Coal Mining Limited (BCML) in Odisha & Rajmahal Coal Mining Limited (RCML) in Jharkhand states respectively.

EMIL diversified into coal mining business following the Government of India’s decision to invite private participation to bridge the deficit in coal production. EMIL became the first MDO in India when it was awarded the Bhubaneswari open cast project, now the largest coal mine, under Mahanadi Coalfields Ltd. (MCL) in Odisha.


BCML

EMIL is the lead partner in the consortium operating the Bhubaneswari Coal Mines Ltd (BCML). Operations commenced in November 2011. Since then, it a history in making. Year after year BCML has surpassed the targets given by MCL. In the very first full year of operation, it produced 11.44 Mn Te of coal and considered as the fastest ramp up of coal production in Indian coal mining history. Year on year, BCML has grown its coal production and achieved the peak rated capacity one year before its schedule. Contractually, it is expected to produce 269.5 MnTe of coal over 15 years. Its contribution in the growth of MCL both volume-wise and profit-wise has been applauded by both MCL authorities as well as entire coal mining fraternity.

BCML’s operations have resulted in higher realisation of coal, hassle free environment for managing operation, optimal time utilization and greater emphasis on environment and safety.

RCML

EMIL is the lead partner in the consortium operating the Rajmahal Coal Mining Ltd (RCML). Rajmahal Coal Mines of Eastern Coalfields Ltd is located in Godda District in the state of Jharkhand.

RCML which operates the Rajmahal open cast mines of Eastern Coalfields Ltd., a Government of India undertaking. The mining operation is expected to produce 200 Mn Te of coal over 12.5 years. The mining operation has started in July 2013.The physical possession of land is in the scope of RCML, in FY 17 -5 (Small hamlets) and in FY 18 -Bhadotola (Major village) rehabilitated. This established itself as partner to ECL in R & R. The coal production figures are:


At RCML, OB stripping is using large size state of art HEMM, including those using ACERT technology engines for fuel conservation and minimizing emission.

Introduction of Surface Miner for 1st time in the Rajmahal OCP to improve quality parameters of coal.

Successful dove-tailing with ECL CHP (20 years Old) without disturbing the existing structures of Ground bunker with conveyor system & a 4 KM Conveyor is being installed for transport of +0 – 100 mm crushed coal directly from the pit to the ground bunker of ECL

For Monitoring of ground vibration, suitable seismographs are being used at RCML

Once the mined out areas become available backfill and subsequent reclamations –restoration is already in the plans.
