Abstract:

To relieve the tension of mining and tunneling replacing of DongPang Coal Mine and to eradicate the problem of slow advancing footage and low level of roadway quality-standardization, this paper, through improving drilling process of hydrogeology, optimizing the design parameters of roadway support, utilizing new devices and new technology, optimizing the labor organization, intersecting reasonably and parallel operation, wall chat operation, reversing schedule and so on, increases the large cross-section’s coal roadway’s advancing footage and creates the new level of 1050m of the monthly advancing footage of the large cross-section’s gob-side entry of DongPang Coal Mine.

Key words: Fast tunneling, Gob-side entry, Labor organization, Tunneling Technology
