Safety issues in the crushing and sorting mills of quarries based on the results of forensic technical examinations

The state of mining enterprises of the Russian Federation, despite the development of high-performance equipment and high-efficiency technologies, the use of modern technical means of monitoring the production environment and other measures, is characterized by the preservation of a high level of severe and fatal injuries. An analysis of the accident investigation shows that prior to 90 % injuries and accidents are caused by staff misconduct, including 60 % due to misconceptions about the actual level of danger. This is because the lack of reliable information at all levels of the production system hierarchy does not allow reliable forecasting and timely prevention of dangerous production situations. It is known that the conduct of forensic technical examinations on labour protection in criminal cases related to accidents at work greatly facilitates the work of the investigator. The purpose of this work was to identify safety problems at crushing and sorting factories of quarries based on the results of forensic technical examinations. The work includes an analysis of the results of technical examinations on labor protection of two fatal accidents that occurred in 2016—2017 at transport systems of crushing mills of two quarries of Perm region and conclusions on them are drawn. The main safety problems at the crushing and sorting mills of quarries were identified and recommendations were proposed.

Keywords: pit, accident, technical expertise, labor protection, employer, enterprise, bunker, conveyor, employee, circumstances of the case.
