Determination of the miners’ individual injury risk as a result of the dynamic manifestation of rock pressure

Abstract

The injury rate in underground coal mining is extremely high. One of the factors leading to injuries in underground mining is rock bursts. Although rock bursts are not the most common cause of injury in this industry, their consequences are extremely severe. At the same time, the level of injuries as a result of the manifestation of this factor remains high and almost does not change over the past years. The paper presents a method for determining the risk of injury of varying severity as a result of rock bursts. Multifunctional security systems that allow obtaining information about the state of the rock mass are analyzed. Based on the data obtained from these systems, the probability of a rock burst is assessed. The paper also deals with the processing of statistical information on light, severe and fatal injuries caused by rock bursts in the coal mines of the Kuznetsk coal basin. On the basis of statistical data and the results of measurements of the main parameters of the rock mass, the value of the individual risk is determined. It is advisable to correlate the obtained value with the average occupational risk in production.
