    • Abstract
  • Taking characteristics of rockburst of the third level transport tip in a coal mine into consideration, a conclusion was gotten that rockburst in the zone was highly-stressed medium rockburst in deep district by analyzing influence factors of rockburst from mechanical properties of rocks and precipitating factors. Electromagnetic radiation method was used to predict rockburst and rational critical indexes were determined through analyzing monitored electromagnetic radiation value. Feasibility of the method was verified by field application. Three blasting pressure-release schemes were put forward and a short-hole blasting scheme with extending the secondary hole was chosen by use of numerical simulation. Perfect rockburst prevention and control effect of the scheme was verified by field test.
