The full-face tunnel boring machine is built for rock tunneling in coal mines and meets required safety standards. It performs well in stable formations and offers much faster excavation compared to older methods
⚙️ Description of Full-Face Tunnel Boring Machine for Coal Mine
This full-face tunnel boring machine is made specifically for digging rock tunnels in coal mines. It’s already been certified for use in coal mine environments, so it meets the safety standards needed underground. In geological conditions featuring relatively intact rock masses with partial self-support capacity—particularly when the rock firmness index exceeds f7, it performs way better than older methods like the cantilever excavator or drilling and blasting. In fact, it can boost work speed by four to six times.. In fact, it can boost work speed by four to six times.
In the world of coal mine roadway construction, this equipment enables a fully mechanized excavation process, representing a pivotal advancement in the modernization and technical upgrading of underground coal infrastructure.
⚙️ Technical Features of Full-Face Tunnel Boring Machine for Coal Mine

Details
The hard rock double shield TBM is a high-performance tunneling machine designed for complex geological conditions, capable of operating in both hard and soft rock.
Details
EPB (Earth Pressure Balance) tunnel boring machines are extensively used for tunneling in confined or pressurized ground conditions. Progressing under pressure, these tunnel boring machines require the use of products with very specific characteristics for optimum productivity in excavating the tunnel at all levels.
Details
Slurry balance tunnel boring machine is well-suited for geological conditions featuring low groundwater pressure and high soil permeability. Which is widely applied to the operation of road, rail tunnels crossing the river and sea.
Details
The open-type tunnel boring machine (TBM) is primarily employed in hard rock tunneling environments characterized by high geological stability and limited fracture zones.
