Analysis On Coal Mine Safety Accident Causes And Forewarning Management Research

The Security Management which is the important composition of modern enterprise management holds more and more important station. It becomes a critical issue of how to build a set of Security Forewarning Management System and use it to assure high efficient and safe operation of coal mine enterprise.Coal mine is the key industry in China, two-thirds of fuel consumption is from coal. From 1990, the yield from coal mine occupied the premier status. With the increase of yield from coal mine; security becomes more and more prominent. Every now and then big and unusual accidents happen. Because of the peculiar working condition of the producing process, there're more dangerous and insecure factors of coalmine industry than other kind of industries. According to some status, in the 50 years from the setting up of our new country, the imperfect management of secure manufacturing brought many accidents and our loss would be added up to more than 500 billion RMB. This big loss severely affected the stable running of coal mine manufacturing. All these give us the cautions of the austere situation and the urgency and necessity to improve our level of security management.This thesis sets out from the above background, focusing on the characteristics of safe production in coal mine enterprise. Taking the theory of safety and forewarning management as its guidance. Based on the statistical analysis on coal mine accidents and causation model, The paper has proposed three underlying causes leading to coal mine accident, which is the instinct reasons, the direct causes and the indirect causes. The conclusion that security management is one of an instinct reason provides the basis for the construction of security forewarning system to. By strictly controlling the leading elements of coal mine safety accident and postpone coal mining casualties is considerably necessary and valuable.The main ideas of this article is identifying the main factors affecting coal mine safety and designing early warning management indicators, constructing of Coal Mine Safety warning indicator system, and building the mine safety warning management system. All these based on the description safety issue on coal mining enterprises and the advantage and disadvantage of mine safety management.The major views are as following:The first chapter sets out explaining the purpose, the current research status and research methods this article.The second chapter focuses on theoretical research, combining basic principles of the early warning and accident causation theory, to point out security early warning management is a new security management model, which helps to change the passive situation of coal mining enterprises and enhances the control ability to potential risk factors solves the coal mine current shortage of precautions defects.The third chapter finds the main reason for coal mine accident based on a large number of cases, which are combined with accident causation theory to identify the mechanism of coal mine accidents. It points out that an accident is caused by multiple factors. If we control or eliminate one of the factors, the accidents can be prevented. The reason causing accident can be divided three levels, which included direct cause, indirect causes and essential causes. Direct cause is the root causes lead to accidents directly. Indirect cause is the result of the direct causes, while the essential reason is the most fundamental cause lead to security incidents occur continuously. The essential reason can be included as safety management and supervision. For the coal itself, because security management can be controlled and improved, the main way to solve security issues is to strengthen its safety management, especially forewarning management, pre-control the direct cause may lead to o accidents and transfer one of "domino". All of these help to avoid safety accidents, completely change the situation of the after-accident control and turn to new preventive security management.The fourth chapter is to establish an early warning indicator system for coal mine safety, including the dig safety factor, electrical transport safety factors, fire and explosion factor, flood prevention factors, safety management factors, staff behavior factors. All these indicators reflecting on coal mine safety management early warning system are evaluated by fuzzy comprehensive decision method. Index system form as follows, laid the forewarning indicators principles based on the causes of coal mine safety accident and clarify forewarning indicators system based on these principles. The indicators are filtrated by three processes. First, I get universal indicator through literature, then accept factor chose by experts, then investigate some coal mine to ensure forewarning indicator system. It points out the mine objects of forewarning management and evaluation method on coal mine, tells how to determine the value of forewarning indicators. Coal enterprises may determine whether to do security measures according to measurement methods and the value of forewarning object of coal mining enterprises dangerous source state.The fifth chapter have constructed the forewarning management system from the function composition, operation mode and organization. Coal mine forewarning management system is composed by subsystems, data storage, show layer three modules. Sub-system forms by the supervisory control subsystem, data transmission subsystems, risk evaluation subsystem, automatic warning subsystem, real-time monitoring. Data storage and data collected by subsystem realize monitoring, evaluation and identification, diagnosis function. show layer reveals warning results to people. Coal mine safety warning management system operation mode is establishing all kinds of sensors to collect data on gas thickness, carbon thickness, humidity, mines pressure etc. All data will be transmit to the ground and evaluated by model methods, then will output early warning signal.
