Abstract

Problem Statement (Relevance). In today’s world there is a need for rationalizing the methods of mining with a constant increase in the production capacity of open pits. In the existing open pits, extraction and loading operations are conducted by using various types of mining equipment: rope shovels, face and backhoe hydraulic shovels, front-end loaders, etc. It should be noted that power shovels are currently the most widespread extraction and loading equipment. Due to its design features, various plans of open pit mining may be used. Front-end loaders, in turn, are mainly used as auxiliary equipment. However, front-end loaders can be used in extraction operations, when process flow charts and design features contribute to achieving maximum efficiency. In some mining conditions, it may be more appropriate to use front-end loaders than other types of mining equipment. Originality. The use of extraction and loading equipment has been described by many scientists, but some data are outdated, while the current research is relevant for modern mining machinery. Results. Data analysis and integration have shown a potential use of front-end loaders as main extraction and loading equipment in open pits. The studies resulted in establishing dependences between digging height and dump height, bucket breakout force and bucket capacity for shovels and front-end loaders. Practical Relevance. The obtained data can be applied both in designing and making corrections to mining operations directly on deposits to provide rationale for choosing extraction and loading equipment operating at a face.
