Chuangyuan CY-R40C: The Ultimate Raise Borer for Seamless Vertical Shaft Excavation

Raised Boring Machine (RBM), also known as a Raise Borer, is a crucial tool in Underground Mining operations, facilitating the excavation of circular shafts between two levels without the need for explosives. This innovative machine is set up on the upper level of the mine, typically on a concrete pad, to begin the drilling process.

The RBM starts by drilling a small-diameter hole, called a Pilot Hole, to the desired lower level. The diameter of this hole typically ranges from 230mm to 445mm (9" to 17.5"), allowing for the insertion of the drill string or extension rods. Once the Pilot Hole reaches the target lower level, the drill bit is removed, and a Reamer head with the required excavation diameter is attached to the drill string.

The Reamer head is then raised back towards the RBM, gradually grinding the hole to the desired diameter while the drill

cuttings fall to the lower level floor. This process ensures the creation of a smooth-walled vertical tunnel, with the necessity of rock bolting or additional ground support depending on the rock type and intended purpose.

Moreover, RBMs like the CY-R40C exemplify cutting-edge technology in Raise boring rigs. These robust machines are renowned for their reliability and versatility, capable of drilling holes ranging from 1.5 to 3.1 meters (5-10 ft.) in diameter. Standard features of the CY-R40C include anti-jamming mechanisms, automatic makeup, and a gradual ramp-up of speed and torque.

Importantly, this model of RBM by Epiroc boasts impressive drilling capabilities, with the ability to reach lengths of 550m to 750m. Additionally, it can operate within a range of inclinations from 60 to 90 degrees, making it suitable for a variety of mining and construction applications.

In conclusion, Raised Boring Machines play a crucial role in Underground Mining operations, offering precise and efficient excavation of vertical shafts between mine levels. With advanced models like the CY-R40C, these machines continue to drive innovation and progress in the mining industry.

Feature:

HIGH PRESSURE LOAD SENSING HYDRAULIC SYSTEM

Crawler raise boring machine hydraulic system with 40 Mpa high pressure has a number of advanced technologies such as constant power control, load - sensing control, multiple filtering proportional solenoid control and so on. In addition, the system stays ahead in mine field. The advanced advantages of higher intelligent degree, bigger power density, stronger anti–dirty ability and higher reliability can ensure that RBM effectively excavate for hard rock.

TWO DRILUNG MODES AND THREE OPERATION MODES

The control system supports two drilling modes (high accuracy drilling mode an speed drilling mode) and three operation modes (manual operation, wireless operation and wired operation). The user can select drilling mode according to accuracy requirement and geological conditions and select operation mode according to operating position and the actual situation.

FULL- MECHANIZED CONNECTING & BREAK NG OUT DRILL PIPES SYSTEM

By means of the automatic positioning technology and two hydraulic wrenches inserted dynamically, the operation that operators connect and break out drill pipes can be accomplished without being directed. The system greatly reduces working strength and saves auxiliary working time.

RCS INTELLIGENT CONTROL SYSTEM

Crawler raise boring machine installs RCS intelligent control system with safety protection automatic operation, fault diagnose, data storage, internet communications, digital display so on ( See specification of RCS intelligent control system)
