Abstract: Taking a coal mine in Shanxi Province as the target, unsafe behaviors were identified by data collection and arrangement, questionnaire and deep interview, and then the safety status levels were evaluated by risk-matrix method and model evaluation method. The main results were as follows: the 842 unsafe behaviors were found in this coal mine. Among them, the amount of coal preparation plant, belt team and airshaft management department were the most, with their ratios in the total amount of unsafe behaviors in this coal mine being as 23.3%, 9.7% and 9.3%, respectively; the species of high-risk-level unsafe behaviors were 172, taking up 14.5% of total amount of unsafe behaviors in this mine. Among which, the amount of high-risk-level unsafe behaviors in coal preparation plant, 1# comprehensive tunneling team and underground electromechanical team were the most, and the amount of high-risk-level unsafe behaviors for maintenance facility fitter, mine-rescue-member and rig drivers were the most; the low level of identification degree for “strict management and discipline could put an end to accident”, ineffective conduction of behavior-correction-activities, non-standardized safety performance examine and other reasons were the 10 main reasons for unsafe behaviors in this coal mine; four concrete measures were finally proposed for the reduction of unsafe behaviors in this coal mine.
