Nevertheless, the improving of the protection in the coalmines are an essential problem for numerous individuals who cares the mines’ lives and excellence of work.
That is why, it is extremely essential to comply with the security laws at any workstations. Another essential problem is making usage of the right underground mining technology.

This equipment ought to be managed by well-qualified employees who are familiar with the safety rules and know how to make use of the devices properly to avoid dangerous. (underground drilling)
Below ground, in the coalmine, there are some tools 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 mining machine, which works underground, in the so-called exploration wall, or in the destination where the coal is straight output. It moves making use of the special conveyor (known as scrapers); it does not make use of caterpillars (such as boom-type roadheader). The CM driver works such a tool by the remote control.

The 2nd equipment used underground is called boom-type roadheader. It moves making use of caterpillars and works underground where drills roadways in the mine. Its front side with the tool drills the rock and move ahead. The obtained coal is transferred at the bottom of the boom-type roadheader.
The last appliance, which will be introduced in the article, is named coal crusher. It is a device used for crushing coals into smaller parts. There are products for crushing mineral coal and brown coal, too.

Avoiding dangerous situations in the coalmines is the goal of the government and the coalmines’ authorities. Unfortunately, there are constantly some accidents caused by nature and inappropriate use of the coalmine equipment. However, there are much less of them and the underground mining equipment is excellent quality and safe.
