Research On Coal Mine Vulnerability Assessment And Strategy Of Emergency Management

Since the nineteen nineties metaphase, China coal production has been ranked first in the world. But with the fast development of the coal industry, coal industry events long continuously, which seriously restrict the further development of coal industry. Although in recent years, the party and government attach great importance to the coal mine safety, enacted a number of laws and regulations and a series of corresponding measures, but the coal security situation has not fundamentally improved. All of this, to understand the mechanism and the accident, development and evolution is not complete, lack of corresponding emergency management idea and method, as well as the emergency management system is not scientific and not sound all has the very big relations. Mine as a vast complex system, in the course of its operation, all the relevant state are open, dynamic, interference and invasion would inevitably influenced by all kinds of security problems, so we need to study a suitable and measure vulnerability identification, emergency management of coal mine evaluation method, and puts forward some more adaptive emergency management strategies and techniques, so the study of emergency management in coal mine accident will have a very real practical significance to the improvement of China’s coal mine safety.The paper starts with the analysis of current situation of emergency management of coal mine and the existing problems, through field investigation and extensive collection of information, the purpose and significance of vulnerability evaluation according to the connotation of vulnerability of coal mine emergency management, in order to determine the affecting factors of emergency management of vulnerability, based on the method of identifying vulnerability factors and identification process, applying the theory and method of system engineering, the effect of emergency management of coal mine vulnerability of all possible factors were comprehensively analyzed, and summed up three kinds of coal mine emergency management vulnerability factors, namely the human factors, material factors and the environment, and makes the detailed introduction of influencing factors. According to main factors of affecting the emergency management of coal mine vulnerability and identify relevant principles of evaluation index and method, a primary index system of vulnerability assessment is divided into personnel, supplies vulnerability and environmental vulnerability evaluation indexes, two grade9, three grade indicators of a total of24. Then using the F-AHP fuzzy analytic hierarchy process to determine the weights of evaluation indexes, on the basis of this, according to the grey difference information principle of grey information system, the non-uniqueness theory is more suitable to solve the evaluation process encountered inaccurate, incomplete, constructs the multi-level grey comprehensive evaluation for vulnerability assessment of grey system theory in coal mine emergency management model based on the score, by determining the evaluation index system of weights, expert evaluation matrix, obtained to determine the evaluation of grey, grey evaluation coefficient, obtained by grey evaluation vector, comprehensive evaluation, according to the authority principle to determine the grey emergency management of coal mine vulnerability belongs to, it belongs to the comprehensive vulnerability level. According to the same principle, can get the level indicators and two indicators of the various specific emergency management vulnerability grade, finally comprehensive vulnerability index, according to the incident frailty Logistic model index and the severity of the incident identified by severity.In order to verify the practicability of the evaluation model, in the Shanxi Jincheng coal mine in Daning as a case study. Multi-level grey comprehensive evaluation model using the emergency management of coal mine vulnerability assessment, available coal mine comprehensive vulnerability index is0.2008, so the mine emergency management vulnerability as the "low", namely the ability to resist risks stronger; according to the vulnerability model Logistic index and the severity of the incident to determine the evaluation result is the mining area a serious injury accident risk. Through the evaluation process, identification and found in emergency management problems and hidden dangers, and to develop practical control measures. Finally, in the light of the main problems and situation of emergency management of coal mine is summarized. Improving measures and suggestions for emergency management of coal mine.The research of emergency management from the traditional to the matter of emergency response and rescue as the focal point for change in emergency preparedness and disaster prevention and mitigation of scientific advance is the core of the model, the prior emergency preparedness as the core of emergency management, change from passive to active response to emergency, disaster reduction center of gravity shifted to the vulnerability identification and control. Through the scientific construction of emergency management of coal mine vulnerability evaluation index system and evaluation model, a new evaluation method theory is applied to the emergency management of coal mine vulnerability evaluation problem, the relevant departments to conduct vulnerability assessment provides theoretical reference for a more comprehensive system. The emergency management of coal mine vulnerability evaluation hierarchy grey comprehensive model, is conducive to a comprehensive grasp of coal mine emergency management capacity, improve the decision accuracy, ensure safety in production of coal mine and more practical.
