One of the methods used in underground mining is called room and pillar, and is often used for mining coal. Part of the mine is open to the surface and part of it is underground. The coal face is dug out, but pillars of coal are left behind to keep the tunnels open and support the roof. Machines called continuous miners are used to remove the coal.

Aug 25, 2020018332To meet energy demand, India plans to upgrade the equipment and technology used in many of its mines, particularly in the coal sector. In 2020, the Indian Government passed an ordinance allowing commercial mining of coal in India and removing all restrictions on enduse of mined coal.
And since these systems are capable of tracking equipment location, miners can use them to analyze dump movement and haul road congestion as well—making changes as needed to keep their coal mining operations running safely and at peak performance.
The coal industry in the United States—encompassing coal mining, processing, and transportation—is a relatively small but vitally important component of the nation’s economy.Coal provides nearly a quarter of all energy supplies in the United States, with most of this coal used to generate more than half of the nation’s electricity.
The tools used by the miner in the process of coal getting are comparatively few in number and of a simple character. After the coal has been broken out it must be carried to the surface by some means or other. This demands the use of certain mechanical appliances which indirectly become part of the equipment of the miner.
In particular, U.S. coal mines and other gassy mines are required to use equipment in certain areas of the mine that has been approved by the Mine Safety and Health Administration MSHA for use in a methane and coal dust environment to limit the risk of the equipment creating an ignitioncapable spark or a thermal energy ignition.
