A mining company loses more from the downtime of an earthmoving machine than from any other breakdown on the site. One excavator produces several thousand tons of rock per shift, and if the machine gets stuck, the entire production chain slows down along with it. Dump trucks are standing, conveyors are idle, the mining plan is being disrupted. That is why the operation of mining equipment is not just a set of regulations, but a key factor in the economy of a mining enterprise.
Briefly
- Quarry equipment includes excavators, drilling rigs, dump trucks, conveyors and dredges: each class of machinery performs its role in the production cycle of mining in quarries.
- The standards for the operation of mining machines are set by the federal rules of industrial safety and GOST standards - non-compliance with regulations leads to an increase in accidents and violation of the requirements of supervisory authorities.
- The maintenance system is built on several levels: a shift-by-shift inspection, scheduled maintenance and major repairs - their observance reduces the cost of restoring equipment by 20-30% compared to the reactive approach.
The concept of "mining equipment" covers a wide range of machines: drilling rigs, dump trucks, wagons, dredges, conveyors and excavators - the main working body of open-pit mining. Among the entire fleet of equipment, wheeled and tracked excavators occupy a central place in stripping and mining operations in the quarries of coal, ore and non-metallic deposits.
The standards for the operation of mining equipment are regulated by federal industrial safety regulations, industry standards, and manufacturers' technical documentation. The documents alone in this system are not enough - it must be applied systematically, from the acceptance of the machine to its write-off.
Mining engineering and technical workers are increasingly engaged not only in how the machine is designed, but also in how to organize its operation so that the utilization rate of the fleet remains at a high level at minimal cost. The key areas are considered below: from the classification of technology to the economics of its content.
Classification of quarry equipment
A modern quarry uses several classes of machines, each of which is responsible for its own section of the production cycle. The structure of the park is determined by the type of deposits, the mining technology used and the performance requirements of the complex.
Drilling rigs form wells for explosive charges - without this stage, the development of dense rocks is impossible. Dump trucks of heavy-duty series carry out the transportation of rock mass from the face to the dump or transshipment
