Q. What has been and what should be the focus of Coal India Limited to ensure a robust growth?
Coal India is faced with meeting challenging targets in the years ahead. Going forward, in order to meet the production targets, Coal India needs to step up growth rate.
To sustain the growth momentum in its production and off-take in the future, Coal India has formulated the following multi-pronged strategies.

(i) Critical Railway Links – Collaboration with State Governments & Railways
There are a few important coalfields in the country which have huge production potential but are without rail linkages for evacuation of coal produced.
Among these, 3 rail lines linked to CCL (Jharkhand), MCL (Odisha) and SECL (Chhattisgarh)
are critical and expected to play a key role in the evacuation of coal.

(ii) Technology Development
A. Geology
I. In geological exploration, hydrostatic drilling is the most state-of-the art technology. CMPDIL has deployed hydrostatic drills for exploration of coal by replacing the conventional mechanical drills. These drills are high-tech and improves efficiency of operation significantly to achieve higher productivity.
II. The tungsten carbide inserts of Crab Bits needs to be replaced with PCD inserts which enables higher penetration rate and improved bit life.
III. To improve boreholes stability, mud mixer assembly may be introduced within the hydraulic system of mechanical drills for continuous mixing of drilling fluid.
IV. Resistivity Imaging System should be introduced for sub-surface geological investigation.
V. Manual hammering technique may be replaced with high power electro-mechanical
vibrating source for generating acoustic wave (e.g. Vibroseis) for greater depth of geological investigation in 2D/3D Seismic Survey.

B. Opencast Mining
I. The latestSoftwareslike GeoviaMinex may be used which facilitates state-of-the-art resource planning through pit design, pit optimization, scheduling of resources and dumps etc.
II. Laser Scanners as TLS (Terrestrial Laser Scanner) for measurement of overburden and mine face, that are in use,entails significantly higher accuracy levels and speed.
III. Use of dronesbe promoted for survey purpose.
IV. A wide variance of HEMM size have been provisioned in coal mining projects. Higher size HEMM viz. Electric RopeShovels of 42 Cum together with Dump Trucks of 240 T have been introduced in CIL mines.
V. Surface Miners ofvarying sizes are being used & proposed for new mines, wherever suitable.
VI. Dozers fitted with rippers are also beingproposed for band and thin seam removal in many of the projects.
VII. For better management and control of HEMM fleet,GPS based truck dispatch system has been introduced in large OC mines.
VIII. The use of silos with rapid loading system in large mines have been stepped up for faster and environment friendlyloading in the sidings.
IX. GPS and GPRS technology are used for vehicle tracking system for better surveillance.

C. Underground Technology
In underground mines, persistent efforts are being made to embark upon the use of mass production technologies,wherever the geo-technical conditions permit.
I. During the year 2015-16, a power support long-wall set having plannedproduction capacity of 0.7 Mty has been installed in Moonidih XVI seam and another long-wall set for Jhanjra mine(having planned production capacity of 1.7 Mty) is under installation. The long-wall set at Moonidih commencedoperation during the year.
II. Four continuous miners have been added and put into operation during the year in three more mines of CIL with totalplanned capacity of 1.84 Mty. Deployment of more numbers of continuous miners are expected in the coming yearsto enable enhancement of production & productivity from underground mines.
III. In 2015-16, the first ever diesel operated Free Steered Vehicle (FSV) has been introduced in Jhanjra mine of ECLfor transportation of men and material.
IV. Additionally, eight (8) numbers of man-riding system has been installedin arduous and long distant mines of CIL which plays a significant role in enhancing safety and productivity inunderground mines. It is envisaged to install more man riding systems in CIL mines in the near future.

D. Coal Washing for Quality improvement
At present, Coal India has a total coal washing capacity of 36.8 million tonnes per year (MTY) through its 15 existingwasheries, of which 12 are coking and 3 non coking with 23.30 MTY and 13.50 MTY capacities respectively.
In addition, Coal India plans to set up further 15 washeries with state-of-the-art and innovative technologies in coalbeneficiation with an aggregate throughput capacity of 112.6 MTY.
Out of these, 6 are coking coal washeries, with acumulative capacity of 18.6 MTY, and the rest 9 are non-coking coal washeries with a total capacity of 94 MTY.

Q. What is illegal mining? What steps coal India has taken to stop illegal mining?
Mining beyond leased area or mining without a lease license or mining even after expiry of leased license is called Illegal Mining.

Coal India has put in place electronic surveillance initiatives to keep watch on its coal stock and to keep a track on movement ofcoal loaded vehicles. Major initiatives include:
a) GPS/GPRS based VTS (Vehicle Tracking System) on coal transport vehicles.
b) OITDS (Operator Independent Truck Dispatch System).
c) Installation of CCTV at vulnerable points like entry/exit points, coal stock yards, railway sidings, material stores, explosivemagazines and important offices.
d) RFID based boom barriers.
e) Wide Area Networking for connecting all the Mines, Projects, Sidings, Weigh Bridges and HQ through dedicated networkfor data transfer and Coalnet implementation.
f) Installation of in-motion Weigh Bridges with RFID tags.
g) Weigh Bridge connectivity for weight tracking.
h) Geo-fencing of mine areas.
