Supporting Design Optimization of Tunnel Boring

Tunnel Boring Machines (TBMs) are a cutting-edge excavating equipment, but are barely applied in underground coal mines. For TBM excavation projects involving the Zhangji coal mine, the The Mine Development Machine (MDM) is a type of non-circular tunnel boring machine (TBM) developed for use in underground mining in rock up to 200 MPa UCS, particularly for long access tunnels and development drifts. Unlike traditional rock TBMs that bore a circular cross section tunnel, the MDM utilizes a reciprocating cutterhead to bore aMine Development Machine Robbins

What Is a Boring Machine and How Does It Work?

Boring machines used in mining and tunneling are typically larger and more powerful than those used in manufacturing and construction. They are capable of drilling through hard rock and soil, which requires a significant amount of power and torque. These machines are also equipped with advanced sensors and monitoring systems that allowThe segment lining is a new type of support structure for mining tunnels. The disturbance of coal excavation leads to the deformation of segment lining and has great hazards to the safety of the tunnels. Based on the tunnel boring machine (TBM) inclined tunnels in Xinjie mine, the ultimate span L0 of the rock beam on the top slab of the coal seam was Mining Hazards to the Safety of Segment Lining for Tunnel Boring
