machines; their working bodies are equipped with cutters. The cutters are placed on the coal mining machines in the amount of 38-96 pieces, depending on the design of the executive body (Fig. 1). Figure 1. Working element of coal mining machine with cutting tools. In 2011 134 coal mining machines operated in Russian.
A continuous mining machine retro-fitted with coated flight bars has achieved overall sound level reductions of 5-7 dB in a laboratory setting. This paper evaluates the effectiveness of this engineering noise control in reducing the noise exposure of continuous mining machine operators in an underground coal mine.
Coal Mining and Processing. Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines. Modern mining methods allow.

The oldest of the basic underground methods, room-and-pillar mining grew naturally out of the need to recover more coal as mining operations became deeper and more expensive. During the late 1940s, conventional techniques began to be replaced by single machines, known as continuous miners, that broke off the coal.
Scrapers are dual-purpose machines performing both loading and transport operations. They are found mainly on infrastructure works sites and at coal mines. The work cycle (scraping) is voluntarily limited by the manufacturers for technical reasons. For further information, please refer to the manufacturer's documentation.

Apr 14, 2010 . One way new technology is not likely to help, at least in the near future, is by replacing coal miners entirely with automated machines, although in some mines it may be possible to operate machinery remotely. Some of the latest mining machinery allows operators to program them to do repetitive tasks, such.
The Mine Safety and Health Administration's (MSHA) final rule requires underground coal mine operators to equip continuous mining machines, except full-face continuous mining machines, with proximity detection systems. Miners working near continuous mining machines face pinning, crushing, and striking hazards that.
Ten feet can be measured with a ten-foot pole; measurement of respirable dust requires a full shift sample that must be weighed by a laboratory away from the mine site. This procedure usually takes several days. During that time, conditions change as the mining machine advances further into the seam of coal. In addition.
