为了更好地提高生产安全性与突出预测的准确性,着重论述了钻屑瓦斯解吸指标△h2的概念、判断原则和确定方法。通过钻屑解吸指标的方法,分析确定了薛村煤矿96261工作面的煤与瓦斯突出情况,在得出数据与结果后,又通过煤与瓦斯突出单项指标的实际测定数据,验证钻屑解吸指标法的准确性。现场检验结果表明采用此种方法能有效地判断该矿突出危险性。
In order to improve the safety of production and the accuracy of the prediction, the concept, judgment principle and determination method of gas honing and desorption index △ h2 are mainly discussed. Through the method of drill cuttings desorption index, the situation of coal and gas outburst in 96261 working face of Xuecun Coal Mine was analyzed and confirmed. After the data and the results were obtained, the actual measurement data of single index of coal and gas outburst were also verified to verify the desorption index of drill cuttings Law accuracy. Field inspection results show that using this method can effectively determine the prominent danger of the mine.
