Since ancient times, man has had to extract certain minerals. Without this, progress was out of the question, for the copper or iron produced was used to make new tools and instruments, and silver and gold were used for jewelry and money.
Mining excavators
The modern mining industry according to the method of mining is divided into two main directions: the open method of mining when materials are extracted in the pit, and underground, with the construction of mines. The machinery used in mining is also divided in the same way – each type of work uses its own, often very specific machines.
Quarry dump trucks.
To work in tandem with excavators and to transport the mined rock in the quarry can not do without special dump trucks. Quite a number of manufacturers produce such machines, but the strongly pronounced trend in recent years is the economic benefit that is provided by high-capacity models, and here not all factories can boast of having giant dump trucks in their product line.
Loaders and bulldozers.
For loading and transportation of loosened rock in quarries, there is also a place for front-end loaders. They are applied in mining since 1970s, both at stripping works, and as the additional loading and auxiliary equipment. Of course, quarry front loaders differ significantly in size from their smaller counterparts.
Other equipment
In a part of open-cast mines there are deposits of strong rocks, for their further working out special equipment is required – boring machines, namely they are used at one of the basic technological operations of drilling and blasting operations – drilling of blast holes. Unfortunately, recently the conditions of hard rock mining have become significantly more complicated, and often the cost of drilling reaches 30-35% of the total cost of mining operations.
There are a lot of companies – manufacturers of mining equipment, but we should not forget that fleet of equipment for each separate quarry is selected individually, depending on production tasks faced by the developer.
