摘要
利用岩石孔隙度和渗透率测量系统，对不同煤质及不同类型构造煤的孔隙度和渗透率进行测试，结果表明，随围压增加构造煤的孔隙度和渗透率降低；不同煤质和不同类型构造煤有不同的变化规律。并进一步探讨了煤的结构、气体压力、气体成分等因素的作用机理。
By using the porosity and permeability measuring system,the porosity and permeability of different types of disturbed coal samples with different qualities are measured.The results show that the porosity and permeability of disturbed coals are decreased with confined pressure,and there are different variation laws in the coals with various qualities and structures.Further,the action mechanism of the factors such as coal structure,gas pressure,gas component and so on are discussed.
