This CGI animation shows the full process of a coal mine from start to finish. The process starts with the underground mining machinery working which includes road header, bolter miner, shutter car. The coal leaves the underground mine via the conveyor system leading to the wash plant and stockpile shed.
's MT series of roadheaders offers the best cutting performance in a wide range of rock formations. Equipped with geometrically optimized transverse or longitudinal cutter heads, these flexible machines can be used for a wide range of applications. They can also be used for rehabilitation of existing tunnels, and excavation of underground caverns.

The roadheader is a machine for excavating rock in mining and civil construction projects. It is a hybrid machine, with better manoeuvrability than that of tunnel boring machines.
A personnel carrier travelling inbye, from the pit bottom area, on a main road collided with the bucket of an Load-Haul-Dump (LHD) that was crossing the road at a cut through. The LHD operator had stopped and sounded the horn but the personnel in the carrier did not hear the horn or see the lights of the LHD and the LHD driver did not see the lights of the personnel carrier.
04-09-2020· Tunnels and underground excavations, horizontal underground passageway produced by excavation or occasionally by nature's action in dissolving a soluble rock, such as limestone.A vertical opening is usually called a shaft.Tunnels have many uses: for mining ores, for transportation—including road vehicles, trains, subways, and canals—and for conducting water and sewage.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and ...

Design of Surface Mine Haulage Roads – A Manual By Walter W. Kaufman and James C. Ault ABSTRACT This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions.
EBZ120 Underground Coal Mining Roadheader Machine is compact in the structure and it is short. The center of gravity is lower, easy operation, stable when working. The cutting head is driven by motors, and it can be both available in the horizontal axis or vertical axis form.
The pillar is design is carried out for both underground coal and metal mine. Conventional theory proposes that local stabilty is ensured if pillar strength exceeds the stress place on it . 17. PILLAR STRESS – The ratio of pillar's estimated strength to the pillars stress is expressed as the factor of safety.
08-09-2020· Coal mining, extraction of coal deposits from the surface of Earth from underground. Coal has been used since the Bronze Age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries.
28-11-2018· Coal mining has been performed since the arrival of the Industrial Revolution in the mid-18th century. Coal is used as a fuel primarily for steam-generated electrical power plants, as well as being a component of certain industrial applications, such as steel manufacturing.
