Research On Gas Drainage Process Parameters Optimization In Zhaogezhuang Mine

Coal mine gas accident was one of the biggest disasters during production process. There were 201 gas accidents and death of 745 people in 2007. The number of gas accidents and deaths is 12.9% and 29.4% in total coal-mine accidents. Coal mine gas accident has become the first killer in China's coal mine production. The occurrence of gas accidents caused serious damage to property and loss and caused enormous shock, seriously affect the image of China's coal mines and even our country. Therefore, the study of coal mine gas control technology and measures to eliminate the gas disaster accidents has become the basis of the healthy development of China's coal industry, and the hot spots and focus of implement people-oriented, comprehensive construction of a harmonious society.Coal mine gas drainage is the prevention measure of manage gas accident. There are two main factors affecting gas drainage: one of them is the coal exploitation gas properties and the exploitation technical conditions and another is drainage technology selection and parameter optimization.Papers based on the analysis of coal seam gas occurrence and impact gas drainage process parameters optimization, the use of drilling radial flow method systematic evaluation of the exploitation of coal bed permeability and the effect of drainage effect. Gray Markov forecasting model could forecast coal seam gas emission. On this basis, the optimum design of the gas drainage method of coal mining face and gas drainage process parameters, through the decision-making computer software, it achieves a coal mine gas drainage process parameters optimization concise and accurate.Zhaogezhuang coal mine gas storage conditions are complex, on the basis of comprehensive statistical analysis of Zhaogezhuang mine gas drainage in many years of experience and data, putting results into the gas drainage work, establish Zhaogezhuang coal mine gas process optimization drainage systems, using it to guide the engineering practice, and to practice and improve in future examination.Mine gas drainage process parameters optimization has provided a scientific and effective way for the mine to achieve a comprehensive prevention control gas and prevent gas accidents disasters...
