• Description:
  This paper evaluates the strata dynamics associated with underground coal mining, particularly Longwall mining, and compares mining and strata control practices for European and us operations. Addressed in the paper are the effects of depth of cover and geological disturbances on ground control. Both gateroad pillar design and face support are evaluated. Load development on shield supports is addressed as are considerations for shield selection and determination of setting pressure and yield capacity. A historical perspective of the evolution of longwall support and recent developments in shield design are described. Recommendations are made for methods to evaluate longwall ground control effectiveness and methods to alleviate ground control problems. [Description provided by NIOSH]
