Large Section Once-tunneling High-speed Driving Technology for Extremely Thick Seam With Burst Potential

For the driving of extremely thick seam with large section roadway and burst potential, the once-tunneling high-speed driving technology of large section is demonstrated from supporting theory, design idea, labor organization, humanistic management and so on. Then, the paper puts forward the management system of taking team management as the core system, and engineering of speedy drivage based on " three technologies", "three times", "four diligents", "four clarities".
