Geoengineering: environmental protection, applied geotechnics, rock and soil mechanics, geohazards 4. Geoinformation: mining geodesy, GIS, photogrammetry and remote sensing, geodata modeling and analysis. List of Scientific Committee, Organizing Committee, Editorial Team are available in this pdf.

Evaluation of modern equipment for automated control and maintenance systems for mine transport

The article presents the results of an analytical study of the equipment of production facilities for automatic control and maintenance of mining equipment. The analysis of the needs of enterprises in parameter control systems and the actual availability of these systems is carried out. Based on the list of parameters, conclusions are drawn about the development of modern automated control systems. The list of parameters was divided into groups to simplify data processing, as well as to be able to draw conclusions about each specific group. The solution of the problem is presented, which allows one to optimize the operation of the equipment and to avoid the occurrence of critical situations as much as possible.

New Solutions for Mine Transport for the Transition to In-Line Mining of Minerals

Mining transport systems largely determine effectiveness of mining enterprises. The study aim is developing new technical solutions for progressive mining transport systems based on the harmonization of technological solutions and equipment. The aim is achieved through the introduction of new mine transport designs compatible with tunneling machinery, enabling change from cyclic concept of a mining enterprise activity to in-line system concept. The option is considered on development of designs of steeply inclined and curving conveyors in transport workings, including overhead and floor pipe belt conveyors and airdraulic pipeline systems for delivering lump ore from the face to the surface in the mine. At the same time, the basis of the proposed technology and equipment is the method of contactless hard rock breaking by using hydroimpulsive facilities. The proposed solutions allow decreasing mineral mining and processing capital and operating costs.

System Design to Prevent the Mine Transport Vehicles Stall

According to the characteristics of the ore under inclined lane transportation, design a kind of system which can prevent the transport vehicle’s speed out of control. The system can according to the different load of transport vehicles and the stall speed given different braking force to expand the application range of the system and increased its practicability. This set of system automation control and flexible intercept, prevent the stalled car accidents, and eliminate potential safety problems.
