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。
Taking the coal seam # 3 of Wangyun Coal Mine as an example, the concept of critical pore size is used to analyze the minimum pore size range that pressurized water can enter. Experimental verification shows that pressurized water injection can improve the wettability of coal and finally the critical pore scale Put forward a reasonable pressure of water injection, coal seam water injection to provide parameters.
