1. Applicable Scenarios
CYTJ76 mining hydraulic excavation drilling vehicle is suitable for
blasting drilling in underground mines, tunnels and underground
workshops, especially for small-section excavation.

2. Technical features
The width of the vehicle body is only 1.45m, with a retractable
safety roof. When the roof is at the lowest position, the height of
the vehicle body is only 1.8m, and normal driving and operation can
be carried out at the lowest height. The maximum working area is
18㎡ (maximum width is 4.5m, maximum height is 5.2m), the drilling
diameter is 41-76mm, the overall structural design is reasonable,
the strength is high, the adjustment and maintenance are simple and
convenient, the equipment has high operating efficiency and good
economy.
Due to its small size, it can smoothly pass through the
small-section tunnels. CYTJ76 has obvious advantages in replacing
manual operations: taking a 28-hand pneumatic drill as an example,
its average drilling efficiency for rocks with F=10-12 is
0.35m/min. CYTJ76 is equipped with a hydraulic rock drill. With the
same rock hardness, when drilling 45 holes, it can handle rocks
with F=10-12 with an average efficiency of 2m/min, and the drilling
speed is 5.7 times that of a 28-hand drill.
In terms of drilling, since the hydraulic system can keep the
propulsion beam completely parallel, the drilling efficiency can
reach 5-8 times that of the air-leg rock drill.
