This standard applies to electrical equipment and electrical installations below ground in an underground coal mine and electrical equipment and electrical installations on the surface directly associated with the underground operations of a coal mine. This standard does not apply to the general surface of an underground coal mine.
The purpose of this standard is to provide a technical standard for selection, installation, maintenance and use of stone dust barriers or other explosion barriers in underground coal mine roadways, to assist in reducing the risk of propagation of an explosion to an acceptable level.
used and was mobilized underground into the mine via a shaft and launched from an underground chamber. Figure 2 shows the TBM used at the San Manuel Mine. The construction of the Rio Blanco water diversion tun-nel to supply water for the El Teniente Mine in Chile was also launched from a large underground chamber within the
Underground coal mining is one industrial activity that has not kept pace with the application of improved lighting technology in the working environment. There are several reasons for this, including the following: 1. Initially, mining lagged behind other industries because (1) early lamps had short service life in this appli-

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
Underground mines have changed their operation systems in accordance with the evolution of equipment, the system and method of mining. Transport is also of critical importance in underground mines as is the mining operation itself. The underground transport system of ores, materials, equipment and persons has been developed from
