Accident Analysis in Relation to Main Roof Structure When Longwall Face Advances toward a Roadway: A Case Study
Practices show that hydraulic supports crushing accidents or roadway supports failure often take place when a longwall face advances toward an abandoned roadway or a predriven equipment recovery room. Therefore, a 2D similar simulation experiment is conducted to reveal the loading mechanism. The res...
