Mine Shaft Hoisting System Security Risk Assessment Studies

Mine shaft hoist system accidents occur occasionally, causing casualties, while also caused damage of the equipment, the duration of the delay or interruption of production, seriously affected the normal conduct of the mine production activities. Causing huge losses to the State and enterprises also have a considerable negative impact. Situation of safety production had faced with great challenges. Study of risk assessment has important significance to carrying out.Under the above background, this article did the following study on safety risk assessment for the mine shaft hoist system:1. Through various accident investigations and summing up for the mine shaft hoisting system, established the index system of safety risk assessment index system for mine shaft hoisting system. From human-machine-management-environment perspective, the index system explored the various risk factors in the system. The index system for mine shaft hoisting system provided a basic level model for safety risk assessment.2. On the basis of summing up the discussion and the entropy theory, reference study on application of entropy theory in other areas of risk assessment, safety risk assessment for mine shaft hoisting system made a systematic study. Introduced the entropy theory into safety risk assessments for shaft hoist system and realized the semi-quantitative evaluation of safety risk assessment for mining shaft hoist system.3. Use the mine shaft hoisting system of safety risk assessment index system and entropy theory based safety risk assessment methods to evaluate the mine shaft hoisting system for safety risk assessments on one mine shaft hoisting system. The result is positive.
