摘要: 針對井下復雜環境因素對煤與瓦斯突出危險性預測指標確定的影響和預測指標確定的要求,著重研究了鉆屑量與鉆屑解吸指標在煤與瓦斯防突中的應用及鉆屑瓦斯解吸指標之間的關系,分析了突出危險性預測中影響單指標值測定誤差的常見因素,并在此基礎上提出了一些指標測定中應該注意的事項和減少誤差的措施.

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.
