摘要
以望云煤矿3#煤层为例,应用临界孔隙尺度这一概念来分析加压水可以进入的最小孔径范围,并用实验验证加压注水可以提高煤体润湿性,最后在临界孔隙尺度的基础上提出合理的煤层注水压力,为煤层注水提供参数。
Take scale is used 3^# coal seam of to analyze the Wangyun Coal Mine for an example, the concept of critical pore minimum range of aperture reached by pressurized water, the experiment is used to verify the effect of coal wetting raised by pressurized water. At last, based on the critical pore scale, the reasonable value of the pressure on coal seam allusion is put forward, the parameters are provided for coal seam allusion.
