Building stone quarrying companies in the Republic of Karelia commonly have limited information on the geological structure of a deposit. They do not have their own geological survey, and this type of service is not yet properly offered in Karelia. When product quality problems arise, it is difficult to rapidly find the correct solution. The quality of raw materials at any quarrying stage can be analyzed using GIS applications at the initial stage of quarrying in order to collect and systematize information on the...

Spatial information became ordinary for everyday use hidden in different kinds of both paper and web maps, navigation, and map applications. People perceive more than 85% of the information by eyesight. Also, the majority of maps is produced for reading with eyes. Visually impaired including blind people perceive the world differently and have the insufficient amount of possible ways how to investigate the surroundings. Also, creating a particular map for blind people is conceptually different, more expensive and ...

The paper presents a mathematical model designed to calculate the depth of the rut formed by a small-sized skidder on soft soils.

One of the reasons for spontaneous combustion of coal waste dumps is the air intake into the body of a dump. Despite the measures taken to isolate the bases and dump slopes, spontaneous combustion of dumps occur in many countries around the world. That breeds a hypothesis that spontaneous combustion process is facilitated by placement of a dump in the geodynamically active zone of the earth's crust. In geodynamically active zone, due to its high permeability, the interaction of the dumps with environment occurs. P...
