焦作煤田煤层渗透率控制因素及预测

Controlling Factors and Forecasting of Coal Seam Permeability in Jiaozuo Coalfield

结合焦作煤田煤层渗透率的现场测试结果和实验室测试结果,分析了煤体结构、煤层裂隙、构造作用、煤化程度、煤岩组分和煤层埋深6个控制因素对煤层渗透率的影响,预测了焦作煤田的煤层渗透性。

Combining with the onsite testing results and laboratory testing results of coal seam permeability of Jiaozuo coalfield,the paper analyzes the influence of six controlling factors of coal structure,coal seam fracture,tectonism,coal rank,coal maceral and coal seam burial depth on coal seam permeability,and forecasts coal seam permeability of Jiaozuo coal field.
