Assessment and management of injury risk of personnel in case of rock failures in coal mines in Kuzbass

Authors: Kolvakh K.A.

Rock failure in coal mines includes roof rock falls. These failures are one of the critical hazards in coal mines in Kuzbass, and can lead to slight and permanent injuries or event to deaths. Although events of different severity traumas because of rock falls reduce in coal mines in Kuzbass, their number is yet abnormally high. The injury risk assessment in different severity traumas of coal mine personnel should use information provided by multifunctional safety systems. Equipment of coal mines with these systems should adhere to the effective normative and legal documents in the Russian Federation. However, risk assessment using the information acquired from the multifunctional safety systems is underinvestigated. Thus, this is a relevant research topic. The article describes the method to determine rock fall probability using the data of geomechanical observations included in the multifunctional safety systems. Then, on the ground of Bayes’ theorem, the failure probability thresholds are estimated; the overrunning of these values brings the risks of slight, permanent and lethal injuries. After that, the personal risk of different severity traumas is calculated.

Keywords: personal risk, multifunctional safety systems, highest likelihood criterion, failure probability, rock mass, Bayes’ theorem.
