Product Description:
Our raise borer KDTJ-2000 borehole diameter of the courtyard drilling rig is between 0.9 and
2.4 meters, with a depth of 280 meters. It can be combined with
freezing and drilling methods to form a comprehensive well drilling
technology, and can also be applied to vertical shaft construction
in underground engineering fields such as hydropower, metallurgy,
subway, transportation, civil defense, and military. Its
application prospects are broad.
Features:
♦ Safe and reliable. The rail mounted raise drilling rig adopts
fully mechanized operation and remote control operation, with a
good working environment and high safety.
♦ High work efficiency and good well quality. The rail type raise
boring machine adopts a rolling cutter mechanical rock breaking
method, with smooth wellbore walls, low deflection rate, and high
well completion speed.
♦ Easy to operate, low construction cost, and good economy.
Adopting advanced hydraulic transmission and control, the operation
is simple, the work intensity is low, and the labor cost is low.
♦ Easy to install. The host adopts a frame structure, with upper
and lower support positioning, high bearing capacity, stability and
firmness. It can be constructed vertically without the need for
preliminary foundation (in cases where the depth is less than 100
meters), greatly reducing construction costs and cycles.
♦ The drill rod has high strength. The drill rod thread of the
raise boring machine adopts the DI-22 international standard, with
a large helix angle and coarse tooth profile, which can effectively
prevent phenomena such as drill rod burning and fracture, and has
higher reliability.
♦ Widely used. The borehole diameter of the courtyard drilling rig
is between 0.9 and 2.4 meters, with a depth of 280 meters. It can
be combined with freezing and drilling methods to form a
comprehensive well drilling technology, and can also be applied to
vertical shaft construction in underground engineering fields such
as hydropower, metallurgy, subway, transportation, civil defense,
and military. Its application prospects are broad.

Applications:
The courtyard drilling rig has a wide range of applications in
underground engineering construction, including mining, tunnel
engineering, water conservancy engineering, etc. In mining
operations, raise boring machines are used to drill holes and
install anchor rods and wire rope nets, enhancing the stability of
the mine; Establish a mine ventilation system to ensure the safety
of miners; Eliminate accumulated water in the mine to prevent
flooding; And transporting ore to improve transportation
efficiency.
In tunnel engineering, raise boring machines are used to drill
holes and install anchor rods to enhance tunnel stability. In
addition, the courtyard drilling rig is also used for sampling and
geological exploration in hydraulic engineering to ensure the
quality of dam and embankment construction.
In terms of infrastructure construction, raise boring machines are
mainly used in construction and transportation engineering. In
construction engineering, a courtyard drilling rig is used to drill
and install concrete piles and retaining piles, providing a solid
foundation for high-rise buildings and supporting structures during
excavation to ensure construction safety.
