Mining industry contributes 2 to 2.5% of total GDP of nation which is 10 to
11% of GDP of industrial sectors.
India possesses the 7th largest reserves of iron ore in the world
Demand of Ore increased
Production of Steel is increased
Manpower planning of Mines and Ore Processing Plant is essential
3. Production need to increase
proportionally with demand
of Iron Ore.
To support the required
production, manpower
planning of Iron Ore Mines
and Ore Processing Plant
(OPP) is required on urgent
basis.

Bowey (1977) defines:
Strategy for matching future manpower numbers and
skills with organizational activities
Lagodimos and Leopoulos (2000) Proposed:
A mixed integer programming based model for the
manpower shift-planning problem
L.H.C. Tippett(1935 ) Develops:
Work sampling (WS) technique, consists of a chain of random
sampling (or observations) of the activities being carried out by
the group of workers (or possibly the machines) under study

9. Work sampling is defined as the
application of statistical sampling
techniques to the study of work
activities. In the audit context, work
sampling is typically used to estimate
the proportion of workers' time that is
devoted to different elements of work
activity. Work sampling is also known as
activity sampling. It can be also used to
estimate equipment or vehicle
utilization

Frequency of Study:
Samplings are made
randomly or at fixed
intervals.
Study Length:
Depends upon the job
type. It is very important
to make sure that equal
numbers of sub-cycles
are included in the study
Establish independent
workload:
This will help insure that
as many of the
underlying variables
which govern the work
performed will be
accounted for.
11. Working continuously without any break
is not possible for any worker. Even
under the best working method situation,
the job will still demand the expenditure
of the human effort and some allowance
must therefore be made for recovery from
fatigue and for relaxation. Allowances
must also be made to enable the worker
to attend to his personal needs.

different HEMMs, their assessment is done
depending upon the vehicle requirement in next
section.
• Manpower (OPP): 5 Company, 27 Contractual
• To determine Manpower required for different
activates in OPP following Mathematical formula is
used:
