The trend of fatal accidents occurring in Indian underground coal mines is higher than in the USA''s and Western Australia''s underground coal mines, as shown in Fig. 1 (DGMS, 2017; Department of Mines, Industry Regulation and Safety, 2018; MSHA, 2017). The different fatality rates from 2002 to 2017 are represented in Fig. 2.
Conveyor belt cleaners designed to keep product moving efficiently from the face of an underground coal mine or the high wall of a quarry.

Thus, of the 86 accidents reported in the coal industry of Kuzbass in the last 5 years, 82 have occurred in the mines, and 42% were caused by underground fires. Statistics on accidents show that up to 70% of exogenous fires in underground coal mines occur in the excavations equipped with belt conveyors because of the fire of conveyor belts.
Although the real HRR curve from a mine fire is important in simulating the fire accurately, the HRR curves for different mine fires may not be available in practice. For the users of the MFIRE program, it is desirable to have typical HRR curves for commonly used combustible materials in underground mines such as coal, wood, and conveyor belt.
and numerous split air reach each working area. Most underground coal mines in India employ an exhaust ( negative pressure) ventilation system. This project deals with the pressure and air quantity survey of an underground coal mine ventilation system at Nandira colliery, Talcher. The survey work has been carried out with the
The subsequent chapters describe dust control methods for different kinds of mines and mining equipment. This includes underground coal and hardrock mines, as well as surface mines, stone mines, and hardrock tunnels. Because dust sampling has so many pitfalls, a chapter on methods used to sample dust is included.

The operation uses underground conveyors suspended by cables from the mine ceiling. Keeping the belts running in the center of the suspended conveyors is a continuous challenge. Martin designed a special suspension bracket to allow installation on the suspended conveyors. Units are built with bronze bearings to avoid problems with static electricity in the underground coal mine.

A Phoenocord St 5400 was supplied for the German hard coal mining group RAG, 15 years later. Like the St 4000 it was for a incline conveyor, carrying coal from underground straight to the surface. Another 10 years later, St 6300 belts were used on bucketwheel excavators in German brown coal .
India has emerged as the third largest coal producer in the world after China and USA with a 9% share of the total global coal production. While the coal production from underground mining in countries like China, USA and Australia are about 95, 33 and 20% respectively, India produces only about 15% of coal from underground mines (Prasad 2009).
