Nevertheless, the improving of the security in the coalmines are a significant matter for numerous individuals who cares the mines’ lifestyles and excellence of work.

This products should be operated by well-qualified employees who are familiar with the security rules and know how to use the devices properly to avoid dangerous. (drilling underground) Below ground, in the coalmine, there are few equipments which help miners to output the coal. They are: longwall shearer, boom-type roadheader and coal crusher. The first device is called longwall shearer. It is a exploration device, which works underground, in the so-called exploration wall, or in the destination where the coal is straight output. It moves using the special conveyor (known as scrapers); it does not apply caterpillars (like as boom-type roadheader). The CM driver operates such a machine by the remote control. (see roof bolter) The 2nd equipment used below ground is called boom-type roadheader. It moves making use of caterpillars and works below ground where drills roadways in the mine. Its front side with the tool drills the stone and move ahead. The obtained coal is transported at the bottom of the boom-type roadheader. The final appliance, which will be presented in the text, is named coal crusher. It is an instrument used for crushing coals into smaller parts. Here are products for crushing mineral coal and brown coal, too.



Preventing hazardous situations in the coalmines is the goal of the government and the coalmines’ authorities. Regrettably, here are constantly some accidents caused by nature and unacceptable use of the coalmine products. However, here are much less of them and the underground mining equipment is excellent quality and safe.
