Study on Surrounding Rock Control Technology of Gob‐Gob Roadway Driven by Fully Mechanized Caving With Large Mining Height and Small Coal Pillar in Extra Thick Coal Seam

Energy Science &Engineering, EarlyView.
The analysis showed that the roof rock beam fractured above the side of the 5 m small coal pillar due to the influence of an anticline structure, leading to the proposal of an asymmetric control mechanism. Grouting pillars and individual supports were used for support, and the technology was successfully applied in the field, meeting the production ...
