3&4 incline existed in same leasehold property of the mine.The upper most seam V ( Khajura) was being
worked by Katkona 3&4 inclines above seam III . Seam II ( Khond) was virgin. The overlying Seam V was
120.0 to 140.0 mt.above Seam III and developed by board & pillar method, average size of pillar varied from
20 mt. x 20 mt. to 35mt x 35 mtcentre to centre and average thickness of Seam I was 2.0 to 5.0 mt , that of
Seam II was 0.90 to 2.00 mt and seam III was 0.90 to 2.50 mt . Coal was being directly loaded onto
poneybelt by extra low height SDLs , And then by a series of belt conveyors coal carry up to UG strata
Bunker . from where through a ROM belt coal carry up to surface bunker and then from surface bunker coal
transported up to Katora Siding by contract tippers.
11) Degree of Mechanisation:-
Bord and Pillar development with solid blasting of coal in seam III was being practiced in the mine. Loaded
tubs from the working districts were being hauled by a series of conveyor belts to underground bunker, from
bunker to surface bunker coal was being transported by conveyor belt.

8. SYSTEM OF STATUTORY INSPECTION AND RECORDS:-
The statutory inspection in the mine is done three shifts (First, Second and Night) by Mining sirdar, Overman
and shift Incharge of Relay A, B,C. In general shift, District Incharge of both the district and Production
Incharge look after the requirement of materials for safety and Production. Ventilation Officer Dusting
Incharge inspect around the mine especially old workings, (isolation, sectionalisation and ventilation )
stopping including air crossing. Safety Officer visits the mine and promote safe practice among the
concerned mine employee and report to Manager about his visit stating that the provisions of Mine acts,
Rules and daily visit the mine and fulfill the requirement of machine and materials used for safety and
production.
Regular Back Shift Inspection is practiced by sr. Officers of the mine. All types of report and records like
Shot Firers, Mining Sirdar, Overman Report Books, manager’s Diary, Electrical Supervisor Log Book ,

TERMINOLOGY OF SAFETY MANAGEMENT PLAN (SMP)
Safety Management Plan (SMP):
SMP is a working document which outlines all the action to be carried out to ensure safety and health
at the workplace based on ‘Risk Assessment’ exercise to be done by a team consisting of workers and mine
management beside others.
Hazards:
It is source of potential harm/situation with a possible to cause loss.
Risk:
It is the change of something happing that will have an impact upon objectives. It is measured in terms
of Likelihood and Consequences.
Consequence;
It is the size of loss or damage and it indicates the magnitude or amount of severity of risk. In terms of
health and safety, it is the degree of harm that could be caused to people exposed to the hazard, the potential
severity of injuries or ill health and /or the number of people who could be potentially affected.
Likelihood:
It is used as a qualitative description of probability and frequency.
Risk Management :
Risk Management is a systematic application of management policies, procedures and practices to the
task of Identifying, Analyzing , Accessing , Treating , and monitoring the risks at workplaces.
Risk Assessment;
Risk Assessment is logical and systematic method of identifying, analyzing and evaluating Potential
Hazards in a particular process/ operation. Hazards are quantified in terms of numbers.

26
Risk Control:
Implementation of strategies to prevent or control hazards.
Risk Management Process
1. Establishing Context:- This means to clearly define the particular task, issue or situation and underlying
hazards that one is trying to resolve as a part of risk management activities. By doing so the risk assessment team
understands what the issue is, where the issue is located and what specifically will be covered.
2. Hazard Identification:- This is the first and the most important step of Risk Management process. Hazards
are best identified by variety of technique that may include-Consultation with mine worker, Inspections, Accident
& incident report, manufacture booklet, safety audits, checklists etc.
3. Risk Analysis:- Analysis risk is the process of adding meaning to the identified hazards i.e. what loss event
could be associated with the identified hazard.
4. Evaluating Risk:- This is done to provide an estimate of resultant risk, in terms of consequences and
likelihood. Most commonly Risk Grid Matrix is used to provide a qualitative measure of the risk magnitude.
5. Treating Risk:- For this Hierarchy of controls is used to identify where we are putting our effort for
controlling risk. The elimination being most effective and PPE & action reliable on human behaviour are least
effective.
6. Auditing & Monitoring of Risk Control Measures :- Reviewing the effectiveness of programmes within
the Safety Management Plan. This should be an on-going process. Both internal and external audits should be
considered. This should be show whether policies, regulations and expectations are being met or where systems.
7. Review: - Once the control measures have been implemented it is important to review them as soon as they
have been implemented and periodically afterwards to verify their effectiveness.
8. Communication: - It is the key ensure that the hazard identification and risk management is fully effective.

Possible Degree of Consequences
While identifying hazards in a classified sector, number of workers who may be exposed need
to be taken in account to ascertain possible degree of consequences in the event of a mishap in
following manner:-
TABLE -1
Serial
No.
Percentage of work persons employed Impact assessment of exposure
1. >40 Maximum
2. 20-40 High
3. 10-20 Medium
4. 5-10 Low
5. <5 Very Low
REVISITING OF SMP:-
The SMP may be revisited when;
1) Geo- Mining conditions changed; or
2) Mining process is changed or altered; or
3) New equipement is introduced in the mining process; or
4) Incident of near miss is reported; or
5) Accident takes place.

PROCESS TO CALCULATE RISK SCORE FOR A HAZARD
Using the equations in Section 6.2.3. of DGMS Cir. No.02/2002 , the following values has been
used to calculate Risk Score for a Hazard.
Risk Score = Consequence x Likelihood
Risk Score = Consequence x Probability x Exposure
Scale for Consequence
• Several dead 5
• One dead 1
• Significant chance of fatality 0.3
• One permanent disability/less chance of fatality 0.1
• Many lost time injuries 0.01
• One lost time injury 0.001
• Small injury 0.0001
Scale for Exposure
• Continuous 10
• Frequent (daily) 5
• Seldom(Weekly) 3
• Unusual (Monthly) 2.5
• Occasional 2
• Once in 5 years 1.5
Scale for Probability
• May well be expressed 10
• Quite possible 7
• Unusual but possible 3
• Only remotely possible 2
• Conceivable but unlikely 1
• Practically impossible 0.5
• Virtually impossible 0.1
Risk = Consequence x Probability x Exposure(CPE) for Maximum –
Maximum Risk – 5*10*10 = 500
Hazard identified as High Risk when (Risk>200)
Hazard identified as Risk requiring Management Action whe (Risk<200 and >20)
Hazard identified as Low Risk but to be reviewed when (Risk<20)

35
Hazard Identification Process
The process of identifying hazards is possibly the most important part of the whole risk assessment
process. Objective is to ensure that all of the possible hazards are identified. Hazards are only discounted
when they have been assessed not to pose a risk. Normally the best process is to proceed step by step
through a task. A number of other processes can also be utilised-
• Previous experience of accidents or occurrence in the mine.
• Work process evaluation.
• Consultation with employees who may have experience in the job.
• Off-side specialists with experience at other mine sites (consultants).
• Fault tree analysis to determine underlying issues and hazards that might not be
evident at first glance.
• Safety statistics for this or other mines.
• Significant incident, near-miss or accident reports
• Inspections in the mine.
Tools of Risk Management
Following documents has been considered for consideration of team,
• Minutes of safety committee meeting
• Workmen’s Inspection report
• Contraventions pointed out by regulators and action taken report
• Safety officer’s inspection report
• Report (s) submitted by Internal Safety Organization, if any
• Previous risk assessment document, if any
• Report (s) on accidents and near misses
