A Case Study on Optimization and Control Techniques for Entry Stability in Non-Pillar Longwall Mining

In order to reduce large deformation failure occurrences in non-pillar longwall mining entries due to roof weighting behaviors, a case study in Halagou coal mine was conducted on optimization and control techniques for entry stability in non-pillar longwall mining. The Universal Discrete Element Cod...
