摘要：
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.
