摘　　要：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, three dimensional model of coal is established. Pressure field, velocity field and deformation of coal were coupled in the numerical simulation of water injection in coal seam, the effect of low pressure water injection on the water injection hole in the same plane parallel drilling was analyzed. The simulation results show that the water injection hole should not be in the same plane, so as not to affect the wetting effect of coal by squeezing each other.
