Declaration of Originality I, Pritam Kumar, Roll Number 214MN1510 hereby declare that this thesis "Reliability, Availability and Maintainability Analysis of the Main Conveyor System in Underground Coal Mine: A Case Study of Churcha (RO) Mine" represents my original work carried out as a postgraduate student of NIT Rourkela and, to the best of my knowledge, it contains no material
Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust. The fire safety requirements are similar for the most hard coal mining countries.
Optimisation of cutting cycles in conventional underground coal sections to improve productivity serves as an area of study that deals with the utilisation of the machines in conventional underground coal sections. Utilisation of machines focuses on reducing the time that machines spend idle and increasing the amount of time during shifts that machines are actively .

Longwall Mining – One of three major underground coal mining methods currently in use. Employs a steal plow, or rotation drum, which is pulled mechanically back and forth across a face of coal that is usually several hundred feet long. The loosened coal falls onto a conveyor for removal from the mine.

The conveyor belt with world's highest tension rating has recently been commissioned at Codelco's new Chuquicamata underground copper mine. End of the strongest underground conveyor belt to date. With the end of German hard coal mining, the strongest underground conveyor belt, ST7500, ceased operation in December 2018.
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6–1.0 m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (1.9–2.5 mi) long and 250–400 m (820–1,310 ft) wide.
The layout of this manual and its easy approach to belt design will be readily followed by belt design engineers. Should problems arise, the services of FENNER DUNLOP are always available to help with any problems in the design, application or operation of conveyor belts.

Underground Coal Mining . Roomandpillar mining is the oldest underground coal mining system, and the first to use the concept of regular roof support to protect mine workers. The name roomandpillar mining derives from the pillars of coal that are left behind on a regular grid to provide in situ support to the roof.
