Quality management of brown coal at open-pit mine in the presence of several consumers with varios requirements to it

Article preview

The article considers main stages of mine planning and modern methods of quality management at open-pit coal mines in Germany. The object of research is the company «MIBRAG GmbH» producing brown coal and providing them a wide range of consumers which have dif-ferent demands to the coal’s quality.

Water economic recultivation of sandy opencasts in Leningrad region as the complex way of decision of region’s environmental problems

Article preview

One of the most perspective recultivation directions of the fulfilled sandy open-cast mines is water economic. There of working out of new more simple and economic projects water economic recultivation is required, thus capable in a complex to solve various geoenvironmental problems. The short review of the basic existing recultivation directions the fulfilled sandy open-cast mines is given. The water economic direction in which the special accent becomes on designing of fire reservoirs is in more details analyzed.

Estimation methods of ore storage’s capacity for opencast startup time

Article preview

It is considered the technique of definition of ore warehouse’s capacity for the period of opencast development. This period is characterized by non-uniform opencast’s productivity on a mineral. The technique allows to estimate an initial ore warehouse’s stock, which is necessary for concentrating factory’s stable work, the possible moment of factory’s starting, and also dynamics of ore’s stocks at warehouse during period under review mining enterprise work.

The integrated reloading point at the combined auto-railway transportation

Article preview

In article it is considered the technology of creation and exploitation of reloading ore warehouse. As the reloading equipment it is offered to use a hydraulic backhoe excavator. At the combined transport the warehouse is an irreplaceable link in a technological chain. Basic difference from existing schemes of warehousing is that ore is housed not in a stack but in a concentration trench. The concentration trench is formed in immediate proximity from a face. It allows to prolong the operation term of the warehouse and to exclude rigid interdependence of the combined transport links.

Justification of optimal parameters of associated minerals stockpiles

Article preview

The majority of mineral deposits are complex, i.e. composed of various minerals. In this case not only the main commercial mineral is mined, but also a number of co-products. As a rule, it is possible to achieve stable extraction of the main mineral, the concentration plant efficiency being directly depended on this issue. Production of co-products is a variable value as it is dependant on the direction and mode of mining operations. This results in disturbances in the concentration plant operation. Extraction of useful minerals from the ore is decreasing. Thus, production of coproducts should be stabilized through storing primary materials at storage areas. Such intermediate storages play an essential role in enhancing the ore grades. The paper offers a method to calculate basic parameters of storages for associated mineral products.
