基于COMSOL软件,建立三维煤体模型,对耦合压力场、速度场与煤体形变进行模拟,分析注水孔在同一平面平行钻孔情况下的低压注水润湿效果。模拟结果表明,临近注水孔不应处于同一平面,以免因注水孔间相互挤压而影响煤体润湿效果。
Based on COMSOL software, a three-dimensional coal model is established to simulate the coupling pressure field, velocity field and coal deformation, and the effect of low-pressure water injection under the same plane parallel drilling is analyzed. The simulation results show that the adjacent water injection holes should not be in the same plane, so as to avoid the influence of the wetting effect of coal due to the mutual squeezing of water injection holes.
