Backfilling of the cavities created by mineral extraction to support the surrounding rock is understood to be an integral part of mining engineering. In contrast to this, underground waste disposal/utilisation is often referred to as a post-mining use of the mine workings, although it requires the same technology and know-how as extraction mining, however with one small decisive difference – ...

The extraction of rock salt at Heilbronn mine by conventional drilling and blasting is investigated on the basis of three key themes: Tests aimed at adapting the blasting pattern show that higher charging densities at the working faces result in greater efficiency in terms of advance per round and, even when all cost variables have been taken into account, can ...

Heilbronn mine, which is owned by Südwestdeutsche Salzwerke AG, Heilbronn/Germany, has for many years been producing rock salt by both conventional mining and mechanical cutting, the two methods being operated separately. With the rearrangement of the mining sections the mine has now recently managed to combine the two techniques in such a way that staff productivity has been increased, average ...

Dewatering in clay mining is one of the most important tasks in the extraction of raw materials, which have a direct influence on production processes as well as on the environment and water protection. The environmental awareness of the clay raw materials industry is of great importance in the Westerwald and against this background, a framework agreement on the discharge ...

Negative environmental effects in connection with mining and tunneling are repeatedly highlighted in the media. Particularly critical are the issues of emissions and occupational safety. Through battery electric machines and automation of processes and machinery, a mine can unlock a number of benefits: improved health and safety, reduced greenhouse gas emissions and lower operating costs. At the same time, battery ...

Along with steel, concrete is used as one of the most important materials in shaft construction and is used in almost every job. Concrete is also used as a building material in construction areas such as structural and civil engineering. Only the working conditions in shaft construction are completely different from those in other construction areas such as building construction ...

In the course of the development of new types of drilling rigs for use in the surface and subsurface areas, which has been ongoing since 2017, a large number of concept ideas and resulting application options have been developed. One focus of these developments is the efficient extraction of reef and gangue ore deposits. The challenge is to develop the ...

The energy consumption of modern belt conveyor systems has fallen considerably in recent decades. Although extensive research has been carried out to produce energy-efficient belt conveyors, there is still considerable scope for further reducing energy consumption, especially for heavily loaded or long overland conveyors. From this starting point, a new rail-based conveyor system has been developed to reduce the energy ...

Mining companies that rely on preventive maintenance should visit the stand of ScrapeTec Trading GmbH, Kamp-Lintfort/Germany, at bauma. The company, which specialises in optimising belt conveyor systems and is known for its contactless AirScrape sealing system, integrates robust sensor technology into a guide roller, evaluates the data in an industrial computer and sends it by radio, e.g., to maintenance software. ...

The Corona pandemic and the Ukraine war are rocking the economy and society. Climate protection is an ongoing issue. Supply chains are partially broken and container ships are waiting to be unloaded in all parts of the world, including Germany. The issue of procurement applies to many companies and the question is: How can we become more independent? As a ...
