Non-coal mine safety supervision mode based on risk monitoring and early warning
Abstract
At present, non-coal mine safety supervision mainly includes safety management inspection and on-site safety supervision inspection. They rely on safety information management platform and on-site inspection by safety inspectors respectively. There are problems of low supervision efficiency, delayed information acquisition, and it is difficult to realize dynamic and comprehensive supervision. In view of the above problems, this paper puts forward a non-coal mine safety supervision mode based on risk monitoring and early warning, considering the characteristics of non-coal mines, such as large number, scattered, poor, small, and the differences in risks and informatization management and control of different types of non-coal mines. Based on the risk monitoring and early warning system of non-coal mine, the risk monitoring index data in five aspects of personnel, environment, equipment and facilities, management and monitoring topics are extracted. The single risk early warning analysis and comprehensive risk alarm analysis are carried out in two ways of risk point and risk surface respectively. The graded push of single risk early warning and the graded control of comprehensive risk alarm can be realized. The monitoring data and special topics of various types of non-coal mines are sorted out. The trigger and disposal mechanism of single risk graded early warning is introduced. This study focuses on the construction process of the model for comprehensive risk research and judgment and graded supervision. Based on the risk monitoring data of non-coal mines, the risk monitoring index system is established. The entropy weight method is adopted to give weight to the risk monitoring index, and the scoring standard is formulated to score the risk index of non-coal mines. Based on the index weight and score, the comprehensive risk level of mining enterprises is determined. The non-coal mine safety supervision mode based on risk monitoring and early warning realizes the graded supervision and inspection of non-coal mines by supervision departments under different supervision periods and ranges. The mode optimizes the allocation of supervision and inspection resources, and improves the efficiency of supervision and inspection.
