摘要
对钻屑指标的原理进行了分析,重点研究钻屑量S和瓦斯解吸指标K1值在实际突出预测中的应用,探寻其在钻孔中的变化规律,并提出测定过程中减少误差的措施与方法。
The principle of drill cuttings index was briefly analyzed.The drilling cuttings weight and gas absorption index of drill cuttings were investigated as an emphasis in practical application to predict the risk of coal and gas outburst.The variation of desorption index for drill cuttings was discussed.The measures were proposed to reduce the errors during the measurement.
