Numerical Simulation Research of Flexible Shield Support Lateral Caving Technology

Abstract:

The arrangement and caving order of the mouths after the shield are the key technological problems of lateral caving in flexible shield support face of steep inclined coal seam,and restrict the production.Based on the geological and production conditions of Muchengjian Mining 5113 flexible shield support face in Beijing mining area,lateral caving was simulated by using PFC2D.Single mouth caving and double mouth caving in different orders were researched.It showd that double mouth caving discharged more coal than the single one.When opening two mouths,caving from the upper to the lower had discharged the most coal.Open the third mouth between the two mouths could discharge more coal.The best technology of caving was caving from the upper mouth to the lower one.It increased the rate of recovery and decreased the workload.
