raising methods in metal mines.
i) Open raising method,
ii) Two compartment method,
iii) Long hole drilling method,
iv) Alimak raise climber,
v) Raise borer
vi) drop raising
i) Open raising method : For moderate length upto 8m and
inclination of 40°-60° with the horizontal. In order to accomodate the
stopper and starting drill steel of 800mm length, a clear hand of 2m
is required.
Description:
 This is simple and most common method adopted in majority of
metal mines.
 The workers stand on a platform made of timber supported on
iron bars into the footwall.
 The drill hole is done by jackhammer and generally done by
wedge pattern.
 Holes are 32mm dia and 1.5m deep.
 Before each round of blasting the platform is dismentaled.
 Immediately after blasting compressed air is forced to the
working face to remove the fumes of blasting and for ventilation.
 The platform is shifted after 2 to 3 round blasting i.e. after getting
a sufficient progress.
Disadvantages :
 Lack of ventilation.
 Damage to pipes and ladders etc, from the blasting.
when raise goes higher:
- loss of efficiency of manpower
- cycle time increases
 dismantling & shifting the scaffold or platform is time taking and laborious work.
