rail fencing which can be erected between the drilling operations and the edge of the
mine can be provided. Attachment of a safety line to the drilling rig and provide
harness for the driller to wear can be done. Newer drill machines are provided with
cabin which controls noise level within cabins. Driller operators should be protected
with ear protection.
5.6.2. Loading
Possible risks during loading of mined rocks are falling of rock on the driver, plant
toppling aver due to uneven ground, failure of hydraulic system, fires, fall while
gaining access to operating cabin, electrocution in Draglines, failure of wire ropes in
Dragline. In order to overcome these risks:
Operator cabin should be of suitable strength to protect the driver in
event of rock fall.
Electrical supply to dragline should be properly installed with adequate
earth continuity and earth leakage protection.
Wire rope should be suitable for work undertaken and be examined
periodically.
Ensure that loaders are positioned sufficiently away from face edges
5.6.3. Transportation
Brake failure, lack of all-around visibility from driver position, vehicle movements
particularly while reversing, rollover, Vibrations, Noise, Dust and improper / no
signalling are some of the factors causing risk. This can be avoided by following
measures:
Visibility defects can be eliminated by the use of visibility aids such as
closed circuit television and suitable mirrors.
Edge protection is necessary to prevent inadvertent movement.
Seatbelt to protect driver in event of vehicle rollover.
Good maintenance and regular testing necessary to reduce possibility of
brake failure.
Avoid driving at the edge of roadway under construction
Heavy earth moving equipment and vehicle drivers and those giving
signals should be well trained.
5.6.4. Unstable face
Chances of Rock fall or slide exists. Regular examination of face must be done and
remedial measures must be taken to make it safe if there is any doubt that a collapse
could take place. Working should be advanced in a direction taken into account the
geology such that face and quarry side remain stable.
