Bucket elevators are characterized by considerable efficiency as bulk material conveyors. Chains or rubber bands are the pulling elements of buckets. The nature of the transported materials often creates the risk of an explosion of a mixture of dust and air. The effort is to reduce the risk of creating an explosive environment and the occurrence of sources of initiation. If this is not enough, devices are used to suppress the explosion by detecting and extinguishing it in time. Further, construction measures are also implemented to reduce the consequences of an explosion - installation of elements for explosion relief or for flameless explosion relief....

The article deals with the mineralogy of secondary minerals at the ČSA site. The subject of the research was primarily the area of the coal seam bedrock at the bottom of the quarry. The main result was the discovery of the relatively rare mineral thenardite. This is the third occurrence in the Most Basin area and the first in the ČSA area. The mineral was determined by X-ray diffractometry on a D 5000 Siemens device.

The Hořany Energy Corridor is a strategically important part of the energy and industrial infrastructure. High safety requirements are placed on the entire corridor, while its newest part passes through the Slatinická dump. A network of continuous geodetic and hydrogeological monitoring was built in previous years for the purpose of detailed control measurement. This monitoring network using IoT principles has become the basis of a geo-information database platform that enables the automation of the process of storing, processing and displaying measured data with the possibility of further future development. A GIS database and a web map application...
