【摘要】 针对井下复杂环境因素对煤与瓦斯突出危险性预测指标确定的影响和预测指标确定的要求,着重研究了钻屑量与钻屑解吸指标在煤与瓦斯防突中的应用及钻屑瓦斯解吸指标之间的关系,分析了突出危险性预测中影响单指标值测定误差的常见因素,并在此基础上提出了一些指标测定中应该注意的事项和减少误差的措施.更多还原

【Abstract】 In order to investigate the effect of underground complex environmental factors on the identification of forecast indicators for coal and gas outburst fatalness and meet the need of determining forecast indicators,the value of drilling cuttings weight and desorption index for drill cuttings were focused on,which were applied in coal and gas outburst controlling.The relation between desorption indexes for drill cuttings was discussed.After analyzing common factors which affect the error of single-index measurement,some attentions in mensuration and measures to reduce the error were put forward in preventing coal and gas outburst.更多还原
