Description |
The production of underground coal is directly
related to the safety of the mine. When any fatality
occurs, mostly due to roof fall and side fall,
production of the mines gets affected. In India roof
fall in underground mines still contributes a fair
amount of percentage, i.e., in and around 40%
towards the fatalities of the accident. Thus the roof
fall in underground mines has to be minimized by
the application of a rational and appropriate
support system. The design of support for soft rock
formation still drives a real concern for engineers as
it requires lots of effort, hard work and experience.
In this study, support design is given for the incline
lip opening in fragile and soft rock geological
formation. The study on the apt support for incline
drivages has also been conducted. Rock load has
been estimated applying CMRI rock mass
classification, Bieniawski’s Geomechanical System
and numerical modeling. On comparing rock load
obtained by CMRI rock mass classification has been
observed on upper side. To ensure the safety and
stability of incline drivages, CMRI rock mass
classification has been considered to design a
support system so as to maintain factor of safety
above two.
