Justification of engineering solutions on reduction of occupational traumatism in coal longwalls

The coal mining industry as an economic activity features an abnormally high level of occupational traumatism. Rock falls are the cause of 17% of fatal cases of occupational traumatism and the second prevailing cause of fatal accidents in coal mines in Russia. This study aims to justify engineering solutions in reduction of occupational traumatism in case of roof caving and rock falls in coal longwalls. The analysis of occupation traumatism, including roof caving and rock fall events, is performed as a case-study of SUEK-Kuzbass coal mines. An innovative engineering design of a powered roof support unit with load-bearing and lead beams enables elimination of traumatism cases connected with roof caving and rock falls during advance of the powered roof support, or in adjustment of the position, insufficient stability and load-bearing capacity of the support, which can reduce the level of occupational traumatism by 22%. The novelty of the research findings consists in structuring of occupational traumatism risks in coal longwalls with regard to the causes, which makes it possible to restructure and reduce the risks.

Keywords: coal mines, occupational safety, longwall, powered roof support unit, rock fall, occupational traumatism, risk dynamics, risk-based approach.
