XCMG Footprint | New Breakthrough! Successfully realize large inclination anchor digging!

May 29, 2024

Recently

100 meters underground from Shanxi Coal Mine

There is good news——

XCMG Roadheader and anchor machine

Successful excavation and anchoring operation with large inclination angle

This is a new breakthrough.

Under the mine，Successful excavation and anchoring operation with large inclination angle

Why is it widely concerned?？

Before answering this question,

Let's get to know first.

Situation on the spot

The geological conditions of this coal mine are complicated.，The average dip angle of the coal seam is 36°，Belonging to a mining mine with large dip angle and three soft coal seams.。A design length of 800 meters，High 4.2 meters，Width 5.4 meters，The slope is over 21°It is a difficult problem in the construction of large inclined uphill roadway.。

“Fully mechanized Roadheader of conventional production in China

Gradeability is 16°

Can't meet our needs.……”

Previously, the project adopted the construction technology of blasting excavation.

The average monthly footage is only 30 meters.

How to ensure safety?

Improve efficiency better and faster？

XCMG has in-depth communication with the project side again and again.

Increase the traction、Braking force，Enhance track grip，Increase safety auxiliary traction，Improve hydraulic system performance，Improve the adaptability of the shipping mechanism，Increase the number of airborne roofbolter......

Through customized professional design

This one“Stuck in the neck”Question

Make a breakthrough

Customized XCMG Roadheader

Large gradient hard rock intelligentEBZ260M-4H

Set tunneling、Support、Dust removal and other functions in one.

Production efficiency has been greatly improved.

It has successfully broken through the difficulty of digging anchor with large inclination angle.

Nowadays，Stable footage of 50 per monthm，The effective rate is improved by 60 percent%Above

Compared with blasting excavation construction，Large gradient hard rock intelligentEBZ260M-4HThe bolter is safe and efficient，It can form a lane at one time.；Compare with that common fully-mechanized Excavator，The use of airborne roofbolter replaces the manual anchoring operation.，And that labor intensity is reduce。

At the same time，The roofbolter can also realize advanced zero-empty roof operation and all-round anchoring.，Construction is safer and more convenient，Quality is more guaranteed，And manpower is effectively reduce.、Financial resources and other costs。
