c) Issue cards stating the name of the contractor and the
work and its validity period, indicating status of VT & IME.
d) Every person deployed must wear safety gadgets
e) To submit to DGMS Returns
- Quarterly (by 10th of April, July, October & January)
Other Recommendations:
With the increased scope of work, some of the
recommendations of IX & X Conferences, which were
supposed to be complied by the Mine Management, will now
be expected to be within the scope of the Contractors,
particularly in the scope of the MDOs.
The Contractors / MDOs have to learn to share these
responsibilities, willingly or under the pressure of penalties
and the Mine Managements have to ensure that these form
the part of the Tender Documents / Contract Agreements.
1. Occupational Health Surveillance:
a) To establish Occupational Health Services as recommended by
7th Conference,
b) The frequency of PME: Three years for employees +45 yrs age.
c) Once a year Eye Refraction Test Employees engaged in driving/

- arrangement for classification of chest radiographs and
- also wherever required facilities for audiometry.
e) Chest radiographs to be classified for detection, diagnosis and
documentation of pneumoconiosis in accordance with ILO
classification for pneumoconiosis.
.
f) Computerisation of all records of medical and Environmental
surveillance.
g) The PME Medical Officer to be trained in occupational health
and use of ILO classification for pneumoconiosis
h) Noise mapping of machines used in the mine,
- personal noise dosimetry of workmen exposed to noise

i) Prior to introduction of machinery in mines:
- Vibration studies,
- Ergonomical assessment of all machines, to include:
* Assessment of work process.
* Assessment of working Aids/tools
* Assessment of working posture
j) Potability tests of drinking water supplied to employees,
once in a year irrespective of its source, preferably after
Rainy seasons
2. Quality Control for Improving Safety:
a) Setup Quality Control Cell for quality assurance of critical items,
b) To notify authorities promptly any defect or failure of approved
items or those having BIS certification, for further action.
3. Increasing Effectiveness of Worker’s Participation in
Safety Management:
a)

Wireless Communication & Mobile / Landline Phones
- within the mine with face supervisors & attendance rooms and
- at offices and residences of Managers & other key officials.
c)
Strengthen communication system within DGMS offices and
mine sites, besides other concerned agencies.
5. Constant Vigil on Dangers from Water Sources
a) Fast and Accurate Mine Surveying and Platting Instruments
along with associated Software.
b) Use of latest Technology like GPS, GPR, Micro-Seismic Systems
to monitor the Workings, Barriers, Water Bodies and other
associated Alarm System.
c) Dump Slope Design and Monitoring using Latest Gadgets like
Target less Theodolite, Infrared Sensors and Monitoring
Instruments.
d) Design Embankments against rivers and jore to guard against
Inundation keeping in view the engineering parameters.
- Show construction details in the relevant plans.
e) Warning Mechanism about impending heavy rains for taking
necessary preventive actions.
f) Also coordination with concerned agencies/departments about
opening of dams in the rivers on the upstream side.
6. Safety Management System (SMS):
[Strategies for Implementation and Path Forward]
a) Employ a sound Risk Analysis Process,
- Conduct Risk Assessment, and
- Develop a Safety Management Plan to address the significant
hazards identified by the analysis/ assessment.
b) Adopt the process of Safety Management System and
- Commit for proper formulation and implementation in totality.
c) Allocate necessary Resources for implementation of the control
measures.
d) Organize necessary Training of all employees with the help of
experts, both national and international,
- for Optimal Adoption of the Safety Management System.
7. Accident Reduction Program:
a) Identification of Fatal Risk Areas and Corrective Measures:
b) Detection of Fire and Spontaneous Heating through continuous
monitoring and analysis of data and information;
c) Introduction of safe methods and system in adverse geo-mining
conditions.
d) Reduction of Accidents during Transportation.
e) Introduction of latest technology for anti collision and personal
emergency devices to track the men and machinery in mines.
f) Elimination of Risk of Silicosis and Pneumoconiosis through
use of effective dust control measures.
g) Regular Medical Surveillance on identified group of persons.
8. R&D and Innovation:
Reversal of Dumpers & Tippers:
- Several accidents have occurred in opencast mines while
reversing of equipment especially in dumpers / tippers.
- The manufactures provide only audio visual alarm and rear view
mirrors in the equipment, but the driver/ operator does not have
a clear view of the rear side of the equipment.
- Operator takes the assistance of a spotter while reversing, who
is exposed to danger of being crushed by equipment.
- The audio visual alarm warning at times may not provide
sufficient time for the spotter and others to escape from the site
and incidents/ accidents takes place.
Provision of Rear Vision System in Equipments
The system provides:
a) A monitor installed inside the cabin and
b) An automatic switch on the reverse gear which actuates ultra low
light camera installed at rear of the vehicle.
The Safety is improved:
• Rear view camera provides clear pictures of objects behind .
• Assists rear view during reversing and turnings.

9. Some Important Safety Features for HEMM:
a) Dumpers:
- Mechanical steering locking to prevent untoward movement
of steering wheel and tyre while work persons working below
the cabin while engine is running.
- Blind spot mirror apart from rear view mirror to enable
operator to have clear visibility of blind spot in and around
dumpers.
- Mechanical type Anti collision device to avoid head to tail
collision on haul road such as tail gate, bumper extension or
any other strong device.
b) Excavators:
- All functions cut off switch,
- Swing Motor Brake
- Vent valve on top of hydraulic tank should be able to be
removed without any tool
- A baffle plate between cold zone and hot zone.
- Provision for Limiting of hydraulic cylinders – Stoppers.
c) Dozers:

d) Common:
- Fire resistant hydraulic hoses in place or ordinary hoses
to decrease the chance of fire. All the sleeves and
conducts where cable /wire are passed shall be fire
resistant.
- Seat belt for operators.
- The approved type of fire suppression system.
Also
The stability of HEMM shall be carried out at least once in year
and after every major over haul by an independent agency.
10. Separate road for Light Motor Vehicles
A considerable number of fatal accidents occurred in the mine
premises of Mechanized Open Cast Mines when Dumpers of high
capacity rare over Light Motor Vehicles on the haul roads.
These accidents could have been averted if the Light Motor
Vehicles would not have been allowed to ply on the haul roads and
a separate road for Light Motor vehicles would have been provided
and maintained in the mine premises.
Therefore, in the interest of the safety of the persons employed in
mines, a separate road in the mine premises for the light Motor
Vehicles-used for inspection and transportation should be provided
and maintained. This road should not cross the Haul Road at any
place in the Mine premises.
11. General:
a) Facilities for monitoring the environmental parameters
b) Arrangements for transport of men where long or
arduous travel is involved,
c) Structured Training in Safety Management of all front-line
supervisory officials, for at least two weeks, once in every
five years.
d) Implementation of recommendations of DGMS (Tech)
Circular No.18 of 1975 (Protection of workers against
Noise & Vibration in Working Environment.)
e) Install properly manned check gate(s) at the entrance(s)
to check entry of unauthorized vehicles in mine premises,
f) All persons engaged at any work within the mine premises
to be provided relevant Training and other job-related briefings
h) Drivers of vehicles to be explained the salient provisions of
“Traffic Rules".
The Time has now come for a Mining Contractor to share all the
responsibilities of a Mine Owner and ensure compliance of all
the recommendations Safety Conferences and the provisions
made under different statutes.
The ‘Mine Owner’, as defined in the proposed amendments of
the Mines Act, also includes a Contractor as Mine Owner. The
Contractors, therefore, should now mentally prepare themselves
for these increased responsibilities.
