摘要
两淮煤田新生界松散层底部含水层分选性差、粘拉含量高。本文以淮北临涣矿区底含为分析对象,探讨底含粒度结构与渗透系数关系,证明底含渗透性由粒度结构决定,渗透系数与粘粒含量和不均匀系数的复相关系数达到83．93%。
Analysis on core samples in Huaibei ＆ Huainan Coalfield, Anhui Province shows poor sorting and high contents of clay minerals for the bottom aquifers of thick Cenozoic system. It is proved with core sample data from Linhuan mining area that the permeability of the bottom aquifers in each section is determined by granularity structure, and the complex correlation index between clay contents and uneven index is up to 83.93%.
