Abstract
A major factor determining the efficiency and economy of underground coal mining is stability of the openings. Gate roadways and intersections are particularly susceptible to ground control problems due to the inherent wide roof span, excessive stress and variable intersection shape. Adverse conditions such as high horizontal stress and abutment pressures from longwalls also have a deleterious effect on ground control.
