Abstract
This paper describes a field study at the Olga Mine in McDowell County, West Virginia, to assess the effects of various mining practices on the control of coal mine bumps. Observations indicated that retreat mining systems that involve sequential extraction along several rows of pillars effectively redirect loads away from the pillar being mined, reducing the occurrence and severity of bumps by spreading the excess stress over a greater number of outby pillars. Other control techniques discussed include the uses of shot firing and auger drilling.
