Product Description
I. General Introduction
DFU-400 Underground exploration drill rig is mainly applied in the fields of coal, geology, metallurgy and
engineering.
It is used for drilling large dia. gas suction hole in mines, gallery as well as coal mine, water injection hole,
and big dia. horizontal hole. It can meet the big dia. roller drilling, hard tungsten-carbide drilling and
percussive-rotary drilling.
II. Main Features
1. It is separate in structure, small in size, light in weight, flexible in movement and convenient in
operation.
2. The hydraulic pump is driven by explosion-proof electric motor through operating system,
then the hydraulic pump enforces hydraulic motor to make drill head rotate, and at the same time, the
movement of drill head is realized by oil cylinder & chain double speed mechanism.
3. Hydraulic chuck can satisfy the function of shackles and power-off protection.
4. The sliding and extending & retracting function of the mast makes it convenient for the bottom
of mast to touches the ground or platform, thus the drill rig will be more stable.
5. The swinging arm and mast can do luffing movement, which satisfy the request of multi-angle drilling.
6. The range of spindle rotating speed is wide and the torque is large.

How to choose a suitable drilling rig?
1. What will you do using drilling rig?
---For water project, core sample, soil test, mineral prospect or others?
2. The depth you need?
---For water well, generally, 30-200m. For core sample, 30-600m, even more.
3. Any requirements to hole diameter?
---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.
4. Working land condition?
A. soil, sand, weathered land, etc. soft stratum.
B. soil, sand, soft and hard rock stratum, mixed one.
C. Mainly hard rock, like granite.
Based on the above information, experienced engineers will help you recommend suitable machine and price. If you have special demands, please tell us in advance.
