Analysis of rock burst accidents in coal mine based on behavioral safety

Abstract

In order to study the behavioral causes of coal mine rock burst accidents, 24Model was applied to analyze the unsafe acts and physical causes of 10 typical rock burst accidents occurred after 2011. The results show that the depth of 80% of the rock burst accidents is over 800 m, 50% of the accident points are located in the fault area, and 90% of the rock burst accidents occur in the state-owned key coal mines. The occurrence process of the rock burst accidents can be divided into two stages: the formation process of the high stress concentration zone and the process of eliminating the rock burst risk. Seven categories of unsafe actions, which mainly include risk operation and failure of anti-impact measures, are obtained to eliminate the failure of rock burst hazard.
