Dear Mr Arunachalam,
Thanks for the free and frank views on the slope-failure related subject accident at Lalmatia.
It is a super failure of the main duty of the management ( Supervision monitoring of the mine conditions). Although, reasons may be be revealed in the DGMS enquiery, but it can be assumed that contract mining has it's own drawbacks if allowed to continue without any safeguards and sole motive becomes cost-cutting corner-cutting attitude of the contractor. The mine-owner (i.e. CIL) also failed in its obligations. A fair DGMS inquiry and recommendation/ implementation of safe-guards will be essential for the practice to be continued.
Thanks Regards,
Hukam Chand Dahiya Mob:8800502229

There may be problem of availability of land.Hence there may be violations.
In the interest of safety owner and contractor have to move.If owner forces contractor or contractor violates in the interest of production such type of accidents may occur.
So Owner and Contractor have to give importance to safety.
The lower management has to give true picture to Top management.Top management should not force for production.Instead if the problem of land or ay other problems are there,Top management have to clear them.
There is no doubt about present education or Professors.
The young graduates are nice and talented.
Top management should not pressurise them for production at the cost of safety.This applies to owner and Contractor.
One more very important issue is that how many mining engineers are deployed in each mine under owner or contractor.
DGMS has to ensure strictly that a good number of mining engineers are deployed under owner as well as contractor.
It should be made mandatory to show records of everybody (owner,contractor,mining engineers,work man representatives)to prove that they do the required to prevent such accidents.
Mainly it is the deployment of sufficient mining engineers that is important and top management should not pressurise them.
thank you,
with best regards,

I agree with you and i am
happy that atleast there is some reaction.We as
responsible persons should be proactive. Such a big mass
would have definitely given warning signals and triggers.
Possibly those present are either ignorant or casual in
their approach. Also there could have been pressure from
interested without knowing the consequencesYet another area
is falling standards in educational institutions . One among
the reasons for falling standards is the lack of faculty
with good field exposure. Also when the students come for
training the attitude of management as well as the trainee
leaves a lot to be desired In general let us take it as an
eye opener to identify hazards concerning slopes and be
proactive. Let us not wait for some one else to point it out
as a violation and then take namesake corrective measures
. In this regard sincere implementation of Safety
Management system goes a long wayRgdsArunachalam

Following strategy may selected
for Pit Slope
Monitoring Long term
Monitoring ~ Seismic
monitoring system may install to detect vibrations caused by
movement and cracking on major fault planes. The frequencies
of vibrations may assess on a monthly basis. The system is
suited to detecting large scale failuresMedium term
Monitoring~ Conventional survey monitoring of
prisms may installed on top benches and alternate benches at
an interval of 50m or so in Zig-zag pattern., which may
monitored by Conventional Survey Instruments (EDM and
Theodolite combination and/or Total Station). The monitoring
may do by automatic total stations like GeoMoS
system.~ Sub-lateral Movement can be
monitored by Inclinometer systemShort term Monitoring
~ Daily visual
inspection of all active mining faces by geotechnical and
operations staff, which identifies areas of concern and poor
ground conditions.~ Identified problem areas
are equipped with crack meters and regular field inspections
highlight the deterioration of these areas. Real time
Monitoring ~ A
mobile, global monitoring system was required to detect and
provide warning of the small-scale brittle failures. The
GroundProbe slope stability radar (SSR) is one of the real
time monitoring system.
In our cases, Short
term monitoring must be conducted by geotechnical engineer/
Mining engineer/ geologist and medium term monitoring with
help of surveying team can give us an initial indication of
Slope status.
This group may have a good
technical discussion on it for the beneficial of our Indian
Mining Industry.

ECL Rajmahal Coal Mine Accident
Rescue Operations going on
Ex- Gratia compensation of Rs. 5 Lakh to each family of
the deceased announced Control Room Set Up at Project
Office of Rajmahal Open Cast Expansion Project CMD, Eastern
Coalfields Limited (ECL) has reported that an incidence of
overburden dump slide/subsidence has occurred in the second
shift of 29.12.2016 at about 7.30 P.M. in the Rajmahal Open
Cast Expansion Project in district Goda, Jharkhand, causing
the unfortunate demise of 7 workers. The company has
announced an ex-gratia compensation of Rs. 5 lakhs each to
the family of the deceased, in addition to the amount to be
paid under the Workmen's Compensation Act. All the
necessary help to the families of the deceased is being
extended by ECL. Two persons have met with injuries and
treated in the Area Hospital. One of them has been sent to
Durgapur for further treatment. Prima facie, it is
observed that the incidence is unprecedented, since an area
of 300 m length by 110 m wide solid floor of the Over Burden
dump area has slid down by about 35 m involving around 9.5
million cubic meters of earth material. This could be due to
failure of the bench edge along the hidden fault line/slip.
Senior management of ECL and State Government officials
have been supervising the rescue operations since yesterday
evening. Till 11 A.M. today, 3 excavators and 7 dump
trucks have been located. NDRF Team has also been engaged
for rescue and relief operations. An
Inquiry has been ordered in the incident by the Director
General of Mines Safety and a High Level Committee of
Experts has been constituted by Coal India Limited to
investigate into the causes of the accident. A control
room has been set up at the project office of Rajmahal Open
Cast Expansion Project of ECL and Shri R.R. Amitabh, GM,
