基于瓦斯地质图的工作面突出区域预测技术
Technology for outburst prediction at working face based on gas-geological map
摘要
Abstract
In order to accurately predict coal and gas outburst risk at working face, a large number of measurements on basic gas parameters were taken on the basis of analysis and compilation of gas-geological data. The prediction indexes and critical values were determined with the study of the adsorption characteristics at 15# seam. In addition, the gas-geological map at the working face was drawn based on the study of gas distribution rale. With the prediction of outburst area, the prediction results were verified. This study shows that the adsorption ability of 15# seam is strong. Therefore, using a gas content 10.0 m3/t and absolute gas emission 4.0 mVmin as the prediction indexes and critical values is sound and rational. Using gas-geology map predicting outburst area and classifying management, the gas distribution can be clearly observed and the division results are reliable. The prediction method is simple, effective and feasible for site operation. The study result has a useful reference value and is of significance for coal and gas outburst prevention.关键词
