Iron underground working place Chengchao risk analysis and management technology

And as a weak link in the preliminary recommendations made to improve the work process. Risk control system, diagnosed as the weighted average 72.19 points, including 75 mining level, mining workshop 72 points, the design and construction of metallurgical and mining team 34 No. l of 69.59 points. Through the system hazard identification, system risk control diagnostics, application security control theory evaluation model Chengchao iron ore mining car to ask the operating risk of the situation and control the status of a comprehensive assessment, the following conclusions: (1) mining plant systems security degree was 65. 53, in the good grade; (2) system risk index for the control effect of 0.41, indicating a downward trend in the degree of system security; (3) risk identification system, the results show that the higher risk of mining plant. Risk by 19 sources, A level 1. Grade B 5, C-level 9, which may occur on the deaths accounted for 78.95% Total risk sources, one person died and more than 3 accidents accounted for 31.58% hazards, accidents occur each year probability of death or serious injury 0.926. 4 security management recommendations are based on evaluation findings can be seen above, the mining plant control system effect coefficient is negative, indicating that the advantages of the system is in danger, risk control systems at a disadvantage, the system security in decline, therefore, should focus on improve job quality and worker safety management level of cadres and security, pay close attention to hidden rectification and the implementation of modern safety management of specific recommendations are as follows: (1) full use of hazard identification information, the implementation of risk control management. The basic ideas of modern safety management is knowledge is dangerous, accidents can be avoided. Hazard identification is essentially a process of comprehensive understanding of risk for targeted security management. Hazard identification should be done from time to time (usually 1-2 years) for a revision in order to timely control the state changes. (2) team conducted a focus on risk prediction pre-control activities. Risk of pre-control activities include team activities dangerous to predict, safety inspection and rectification of the three aspects of risks. Dangerous to predict activity is an important education reform team security measures to control human error, improving their safety awareness and safety skills, the implementation of safe operation and personal responsibility, the job safety education, real \Security check system implementation is the premise of dynamic feedback control. Emphasis on the mining risk should check the shop and workshop, section of the mobile inspection, and check the contents, line inspection, cycles to make specific provisions. Hidden nature of the rectification is to improve the hazard level of an important means of security should be based on ease of hidden rectification, classification for. The major risks can not be rectified in time. Rectification before the development of reliable temporary measures to control the casualties caused by its not being triggered. (3) further efforts to improve and implement rules and regulations including block caving mining method to supplement and improve the relevant safety requirements, to seriously implement the cans up and down the shaft to enhance the management of staff, stop transmission management, and shooting (especially the second solution Gun) Safety management, team organization and other safety activities. (4) to strengthen the system of feed-forward control. Through inspection and testing, to detect the production process into the factors related to changes in regulation of the conduct to ensure the safe operation of the system. (5) to implement or improve the three-tier security evaluation to truly create a dynamic binding mechanism. Safety evaluation work is a division of upper management to understand effective means of management deficiencies. Safety evaluation of work-site inspections should be noted that the accumulation of normal, El regular routine check of information obtained and accurately reflect the actual safety management. (6) to strengthen information management well developed security information management system as early as possible from the perspective of modern scientific management control information is a prerequisite. Information management, including information collection, transmission, processing, storage. And even the way from the current wave of mining iron ore plant security information management situation, the security information of the accumulation of a lot of work to do. Proposal to further regulate some information tables in order to develop safety management information system, to achieve long-term storage of security information to improve the speed and quality of information processing, optimizing safety information delivery channel. (7) we will focus on dangerous parts of the control. Including the shaft hoisting system, blasting equipment, haulage, oxygen bottles and the proper use of acetylene cylinders, electrical facilities, day chute, in high pressure areas to develop dangerous face and so on. 5 Conclusion Chengchao iron levels in the Wuhan Iron and Steel under the leadership of the company, after the mine workers at all levels of leadership and the concerted efforts of the whole ore, the basic form of the mineral, workshops (Section), three levels of safety assurance system team, all mine safety steps into the track of healthy development. Of course, safety management Chengchao Iron deficiency still needs further improvement and refinement. But if we are serious implementation of modern safety management, safe working Chengchao Iron will leap to a new level. Mouth
