Micro computed tomography data for: X-ray µCT investigations of the effects of cleat demineralization by HCl acidizing on coal permeability

UCS ROI Pre = this is the Upper Core Section's Region of Interest before acidizing
UCS ROI Pst = this is the Upper Core Section's Region of Interest after acidizing

LCS ROI Pre = this is the Lower Core Section's Region of Interest before acidizing
LCS ROI Pst = this is the Lower Core Section's Region of Interest after acidizing

UCS ROI Pre 指的是在酸化处理之前，上层核心区域的感兴趣区域；UCS ROI Pst 则是指酸化处理之后，上层核心区域的感兴趣区域。
LCS ROI Pre 指的是在酸化处理之前，下层核心区域的感兴趣区域；LCS ROI Pst 则是指酸化处理之后，下层核心区域的感兴趣区域。
