摘要
根据突出区域预测理论制定了突出危险区域划分指标,它包括瓦斯压力、瓦斯含量、煤的坚固性系数、瓦斯放散初速度、钻屑指标、综合指标D和K、工作面瓦斯涌出量和煤与瓦斯突出点;并结合桃园煤矿具体的指标测定情况对其进行了突出危险区域划分,为下一步突出煤层瓦斯治理提供了依据。
On the basis of the theory of outburst, regional prediction of the index of divison has been established, including gas pressure, gas content, initial speed of methane diffusion, coal rigidity, synthetic index, cuttings indes, gas emission for coal mining face, as well as outburst point. Combining with index mensuration of Taoyuan mine, compartmentalize the danger zone of coal and gas outburst. It provides gist for gas controlling on coal outburst in future.
