钻屑瓦斯解吸指标K1值作为突出危险性预测和效果检验的一个重要指标,测试结果的准确性直接影响到煤层是否具有突出危险性。实验室及现场研究发现,“混样”是影响突出预测预报准确性的重要因素。通过现场试验,采用定点取样器取样可解决“混样”的问题,从而提高预测预报的准确率,最终可有效防止所谓的“低指标突出”的发生。
The K1 value of the desorption index of the cuttings and chips is an important index to highlight the risk prediction and effect test. The accuracy of the test results has a direct impact on whether the coal seam is of outstanding danger. Laboratory and field studies have found that “mixing” is an important factor that influences the accuracy of forecasting. Through the field test, using fixed-point sampler sampling can solve the problem of “mixed sample”, so as to improve the accuracy of forecasting and forecasting, and finally prevent the occurrence of so-called “low-index highlighting” effectively.
