文章通过实验室对煤体滲透中的测定得出以下结论:实验室测定结果还不能直接应用于现场实际,只能做定性研究阶段:在煤样应力升高时,可用负指数方程和应力降低时可用负幂函数方程来分析煤层开采前后渗透率的变化情况;突出煤的渗透率小于非突出煤层的渗透率;平行层 理煤样渗透率大于垂直层理的渗透率.因此,煤体的渗透率可作为煤层突出危险的一项指标。
The article through the laboratory on the measurement of coal penetration obtained the following conclusions: The laboratory test results can not be directly applied to the actual field, can only do the qualitative research stage: In the coal sample stress, the available negative exponential equation and stress reduction The negative power function equation can be used to analyze the change of permeability before and after coal mining; the permeability of protruding coal is less than the permeability of non-protruding coal seam; the permeability of parallel stratified coal sample is greater than the permeability of vertical bedding theory. Permeability can be used as an indicator of salient coal seam hazards.
