Research On Key Technology Of Gas Management

The coal is the principal energy in the industry production in our country, and the industry of mining technology has made the extremely important influence to the de-velopment of our country's society and economics. The gas is the derivative in the process of coal production, also is the important factor that affects the safety during the production procedure. The research work related to the gas disaster has been therefore the extremely important significance for constructing the harmonious society, and maintaining the production safety of the coal. The dissertation makes research on the predicting method of gas and prevention of gas process management which are related to the gas disaster, based on management science and artificial intelligence.Based on the analysis of the mechanism of gas production and some influence factors of gas output, the dissertation studied some predict methods of gas out-put.Considered to the gas output history data from coal mine production can objec-tively response the mutual relationship between gas output and its influence factors, the dissertation established the forecast model to solve gas output's predict problem based on the output history data. The paper through constructing information-tables of gas output and neural network which has self-learning capability to establish the fore-cast model of gas output, and attempted to study gas output by analyzing chaotic time series methods, and discussed the reconstruction question in the phase plane to the his-tory data of gas output. The research work and the preliminary application indicated that the forecast method based on the gas output data has the certain superiority.Through analyzing gas migration rule, the accident cause, management system, and management flow foundation, studying exist problems in the gas management, the paper proposed the spirits of safety responsibility management and the management principle, thus established safety responsibility chain management model that suited in the gas process control, and discussed responsibility object , the responsibility unit , the responsibility structure relationship ,the responsibility content in the safety control re-sponsibility chain.. Responsibility chain management mode that suited gas process control obtained the preliminary application in the coal mine gas management practical work.The paper studied the problems about personnel escaping way when the gas disas-ter happened .Through analyzing the influence relationship among selective escaping way and the weight of tunnel, the height of tunnel, the slope of tunnel, throttle facility in the tunnel, the paper proposed the optimal model of personnel escaping way when the gas disaster happened through taking the optimal goal as the equivalent length of tunnel. The paper studied the optimal model's solution strategy of personnel escaping way using the marking method .Based on analyzing miners'quality, miners'studies to safeguard function of the gas safety management , the paper discussed four essential factors: the power of gain-ing knowledge, the ability of gaining knowledge, the ability of internalizing knowledge, the ability of out-initializing knowledge ,which constituted miners'learning ability.The paper studied miners'learning ability function model, designed the methods of promoting miners'learning ability. The paper also established diagnosis pattern of miners'learning ability by hierarchy analytic method. The above research work ob-tained the preliminary application in the actual supervisory work of the coal mine.The paper finally studied the problems about coal mine's security cultural recon-struction. Faced to the existence questions in the traditional security culture, with the aid of the management theories in the study organization, the paper proposed the spirits of constructing study security culture of coal mine and studied its security culture model. The paper studied the security core idea, the security culture safeguard system, security culture constraint condition and its movement way. The paper also proposed study security culture assessment method based on the balance idea branch customs station. The paper obtained the application in the coal mine security cultural recon-struction aspect research results in the coal mine production practice.
