Abstract

A center-pillared full-face shaft drilling machine comprises a center pillar (1), device platforms (2), a derrick (3), a driving system (4), a personnel and material conveying system (5), a well wall support and protection system (6), a safeguard system (7), and an operation chamber (8). The derrick (3) is mounted at a wellhead. The operation chamber (8) is disposed on the derrick (3). The center pillar directly leads from the well bottom to the wellhead and is connected to a slide rack comprised in the derrick on the ground. The driving system (4) is mounted at the front end of the center pillar (1) of a device. The multiple device platforms (2) are sequentially mounted on the center pillar (1) of the device from rear to front. The personnel and material conveying system (5) and the safeguard system (7) are separately mounted on the device platforms at the rear of the driving system (4) and on the ground. The well wall support and protection system (6) is mounted on the device platforms at the rear of the driving system (4) and around the driving system (4). The shaft drilling machine solves the construction problem of large shafts in mines and the like, implements parallel construction operations of automated mechanical integrated complete devices having a series of functions such as shaft driving, residue discharging, support and protection, drainage and ventilation, facilitates dismounting and mounting of the device, saves preparation time, improves the construction efficiency, reduces construction cost, improves construction safety, and has a wide application range.
