摘　　要：通过对公乌素地区16#煤的渗流物理参数测定,用综合评价方法对该地区16#煤的注水效果进行了评价。评价结果表明,16#煤层渗透系数初始值为2.432,镜质组最大反射率平均为1.13%,裂隙分形维数为1.512 4,孔隙率为6%,平均水-煤接触角为68.2°,研究认为公乌素16#煤属注水效果中等的煤层。为提高注水效果,采用了延长注水时间、重复注水等措施,有利地解决了该地区16#煤层的顶煤冒放性差、放煤过程粉尘大等问题。According to the seepage physical parameters measurement at No. 16 coal of Gongwusu Area, comprehensive evaluation method is used to evaluate the effect of coal injection. Experimental data show that the seam permeability coefficient is 2. 432 ;the average maximum reflectance of vitrinite is 1.13% ; fracture fractal dimension is 1. 512 4 ;porosity is 6% ; the average watercoal contact angle is 68.2°. Studies suggest that the injection effect of No. 16 coal in Gongwusu Area is moderate coal seam. Extending injection time, using repeated water and other measures are good solutions to enhance the effect of injection. It also can solve the problem of poor cavibility of the top coal and more dust during No. 16 coal caving.
