    • Abstract
  • In order to overcome the existing shortage of coal mine deep rock breaking technology, the proposed static rock breaking technology should be applied in deep underground rock breaking work. Based on theoretical analysis of the principle of static breaking, we knew that rocks were broken by tensile failure, and proposed the technical requirements and positive effects. Engineering test in K8113 face reduced a large range of top roof hanging issue. After the test, roof distance was shorter than untreated about 10 m, reduced by about 50%, which indicates that the static rock breaking technology in deep rock-breaking work in coal mine is feasible and effective.
