The drilling process itself involves a technique known as 'circulation.' A drilling fluid, commonly referred to as 'mud,' is continuously pumped down the drill string, through the bit, and back up the annulus between the drill string and the walls of the hole. This fluid serves multiple purposes it cools and lubricates the bit, carries cuttings to the surface, stabilizes the borehole, and provides hydrostatic pressure to prevent underground fluids from entering.

Corrosion is a universal concern, causing significant economic losses and structural degradation in various sectors. Traditional materials like steel and concrete are highly susceptible to chemical attack, leading to weakening and eventual failure. However, FRP's unique properties make it a game-changer in combating this issue. The non-metallic nature of FRP ensures that it is not subject to electrochemical reactions, which are the root cause of corrosion in metals. Moreover, its chemical inertness allows it to withstand exposure to harsh environments, acidic or alkaline substances, and extreme temperatures without degrading.

Coal drilling is not a task for the faint-hearted, nor is it a job that can be accomplished without the right equipment. It demands robust, high-performance drill bits that can withstand the harsh conditions of the earth's crust and the abrasive nature of coal. The primary function of a coal drill bit is to penetrate the rock layers, creating boreholes for blasting or inserting mining machinery.
