潘一矿煤钻屑瓦斯解吸指标Δh2值的突出敏感性及其临界值
Sensitivity and its critical value of gas desorption index △h2 in coal drilling cutting at Panyi coal mine
摘要
Abstract
Based on current study on sensitivity index and its critical value of outburst prediction at coal face in China, this paper proposes an assessment method that uses coal drilling cutting gas desorption index △h2 as a critical index for assessing outburst in coal face based on theoretical analysis, laboratory experiments and site test. A case study at 13-1 coal mining face in Panyi coal mine demonstrates the method proposed using three rates method and grey correlation theory. The problems that crossing of sensitivity indexes and fuzziness of critical values are overcome using coal drilling cutting gas desportion index △h2 as a critical index for outburst in coal face. In addition, the adaptability of sensitivity index is improved.关键词
