The article describes design principles for autonomous cargo transportation systems and social aspects of their implementation. Economic prerequisites for creation of autonomous cargo transportation systems in Russia and in the world are analyzed as well as the composition of the complex autonomous system. Issues of economic justification for implementation of autonomous cargo transportation systems, regulatory framework and safety provision of autonomous dump truck application are also addressed.
This article considers one of the approaches to solving the problem of improving the efficiency of the functioning of unmanned open pit transport. The actual data on the movements of robotic dump trucks within the framework of a continuous transport and technological cycle at one of mining sites of a coal mine are analyzed.During the study, the movement times in the loaded and empty states are recorded. In addition, the time of passing by dump trucks of individual sections of the transport route is monitored, in order to empirically determine the speed reserves for each robot. As a result, several options have been obtained to increase the target performance of an autonomous dump truck by changing the speed modes of movement in certain sections. One of the variants is presented in the paper as an illustrative example. The paper also briefly discusses possible approaches to formalizing the procedure for determining the optimal driving modes of robotic dump trucks, depending on the terrain and features of the route as well as the roadbed condition.
Digital transformation of the economy is a global trend. Digitalization has become a strategic priority for most companies no matter which industry they belong to, which form of property they are and how specific their business is. The article presents strategic priorities of digital transformation of Kuzbass coal industry. These priorities are part of ‘Strategy for social and economic development of the Kemerovo region (Kuzbass) up to 2035 and for longer perspective’ developed under the guidance and according to methodology of Dr. V.L. Kvint. Strategic analysis of world leaders’ activity in mining industry has shown that the first step to digitalization is connected with changes in the strategic management system and creating a digital transformation centre. The authors define the levels of digitalization of a mining company: automated production, digital flow control, “clever production”. The basic strategic priorities of digitalization of coal industry of Kuzbass are automated dispatching systems, equipment reliability management, energy efficiency of production, robotization, digital modeling, industrial labour safety and security. Coal industry enterprises create their own way of digital transformation and determine the list of essential digital technologies by themselves. Kuzbass coal industry will become the largest regional individual buyer of innovations and technical decisions in the nearest perspective. Digital transformation of coal industry will help automate the industrial process, increase labour and equipment productivity, and raise the level of industrial and environmental security and the industry’s efficiency indexes, and improve the life quality of employees and people of Kuzbass.
The article addresses the issues of ensuring safe operation of mining equipment in surface mining. It describes the main factors and situations that pose a high risk to human life and health. The most dangerous incidents are shown to be related to limited visibility and blind spots for operators of mining equipment, which can result in collisions and personnel run over. The main technologies and specific solutions used to design collision avoidance systems are described and their general comparison is provided. A particular focus is placed on monitoring the health of employees at their workplace by means of portable personal devices that promptly inform the dispatcher of emergency situations. General technical requirements are formulated for designing of the system to prevent equipment collisions and personnel run over in surface mining operations. The paper emphasizes the importance of introducing a multifunctional safety system in surface mines in order to minimise the possibility of incidents and accidents throughout the entire production cycle.
