STUDY OF THE INFLUENCE OF DYNAMIC LOADS ON THE OPERATION OF MINING MACHINES

Abstract

The dynamic loads that occur during the operation of mining machines are an important aspect of the safety and efficiency of mining. These loads can be caused by various factors, such as surface irregularities, changes in speed and direction of movement, ruptures of materials during blasting, and others. They can lead to accelerated wear of machine parts, increased fuel consumption, increased technical stops and emergency situations, which threaten the safety of workers and reduce mining productivity. The purpose of this study was to study the dynamic loads on mining machines and establish optimal ways to reduce these loads. The research was carried out with the help of mathematical modeling of processes. The main parameters that affect dynamic loads include the speed of the machine, the overall dimensions of its wheel base, the degree of filling of the bucket and others. The obtained results of the research made it possible to determine the optimal methods of reducing dynamic loads on mining machines. For example, it has been established that the use of adaptive undercarriage control systems allows reducing the impact of surface irregularities on the machine and reducing the risk of its overturning. The obtained results can be used to increase the safety and efficiency of mining machines, which in turn will contribute to increasing the productivity of mining production and reducing its impact on the environment. The load of the elastic system of the working body when the external resistance changes as a function of speed is proposed, which allows to reduce dynamic loads and reduce the energy consumption of the work process.
