摘要
通过对几种不同煤层煤样的孔隙特性分析 ,结合实验室试验 ,确定出水在煤孔隙内渗透与保存的最小孔隙为 0 0 7～ 0 2 2 μm ,平均为 0 1 4μm ,提出了沟通孔隙率这一新概念 ,并导出了沟通孔隙率与煤层注水增量的关系 ,对指导煤层注水具有实际意义 .
Based on the characteristic analysis and laboratory test on coal samples taken from different seams, the minimum coal pores for water permeating into and maintaining in them is determined which have the size from 0 07 μm to 0 22 μm and 0 14 μm on average, a new concept of linked porosity is put forward and the relation of the linked porosity with water infusion increment in seams is derived, which have actual guiding significance for infusion in coal seams.
