Abstract

To study the mechanism and control technology of fully mechanized caving gob-side entry driving under the dynamic pressure, S1202 working face of Yuwu Coal Company is taken as objection, a formula for the depth of plastic zone of the roadway floor strata is drawn by analysis the bottom plate force; then the paper analyzes the deformation and failure characteristics of roadway floor under the dynamic pressure. The studies showed that the roadway floor strata were asymmetric deformation, which put forward a reasonable floor heave control technology.
