Coalmines are 1 of the most harmful work places in the world. The coal offers heat and frequently also electricity but output of coal occasionally means dangerous incidents, gas explosions or other situations, which are commonly described in the papers when the worst takes place.

However, the improving of the security in the coalmines are a significant matter for many people who cares the mines’ lifestyles and excellence of work.That is why, it is quite significant to comply with the security laws at any workstations. Another essential issue is using the right underground mining equipments. This products ought to be controlled by well-qualified workers who are familiar with the safety rules and know how to make use of the machines correctly to avoid dangerous. (underground drilling)Beneath the planet, in the coalmine, there are few 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 device, which works below ground, in the so-called exploration wall, or in the place where the coal is directly output. It moves making use of the particular conveyor (named scrapers); it does not apply caterpillars (like as boom-type roadheader). The CM operator works such a tool by the remote control. (roof bolter)The 2nd equipment applied below ground is known as boom-type roadheader. It moves using caterpillars and works underground where drills roadways in the mine. Its front part with the tool (mines machine) drills the rock and move forward. The obtained coal is transported at the bottom of the boom-type roadheader.The last equipment, which will be presented in that text, is known as coal crusher. It is a tool made use of for crushing coals into smaller parts. Here are machines for crushing mineral coal and brown coal, too.

Avoiding hazardous situations in the coalmines is the priority of the authorities and the coalmines’ authorities. Unfortunately, there are constantly many incidents created by mother nature and unacceptable usage of the coalmine equipment. Nonetheless, here are much less of them and the underground mining equipment is excellent quality and safe.
