Article Highlights
-
The three-dimensional patterns of hydraulic fractures are presented with in situ underground observations.
-
The coal body structure and coalbed structure greatly affect the hydraulic fracture geometry.
-
Hydraulic fractures mainly develop in undeformed coal and weakly deformed coal.
-
Weak layers and strongly deformed coal should not be perforated during fracturing engineering.
