Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This article considers the problem of occupational health and safety in crushing and grinding mineral ore at the processing plants of mining enterprises.Occupational risks at workplaces are dust of complex composition (aerosol of fibrogenic action), industrial noise (80-105 dB) and vibration (up to 43-56% of working time), unfavorable microclimate.In the structure of occupational injuries, injuries of musculoskeletal system, concussions of the brain and contusions prevail.The aim of the study is to review the literature to identify occupational hazards of workers employed in ore crushing and grinding areas in order to compile a body of knowledge to investigate safety in the workplace.The study synthesizes theoretical statements and results of 38 scientific papers published between 2000 and 2023 in PubMed, Core Collection in Web of Science, ScienceDirect, and RINC databases to display the existing body of knowledge on occupational hazards in ore preparation for further processing in mining companies; PubMed database data were processed by VOS Viewer 1.16.18;descriptive analysis and textual narrative syntheses were compiled through a systematic literature review.Data on occupational risks of occupations such as plate feeder and conveyor (transporter, elevator) operators, crusher operators (jaw, cone, roller, hammer), screen and mill operators were obtained.The results of this study can provide useful information for making proposals for organizational and technical improvement to reduce occupational morbidity during ore preparation at concentrators and reduce the limitations of socio-economic consequences of occupational diseases and accidents.
