The XW milling and excavating machine can be installed on any type of hydraulic excavator, efficiently replacing general configurations such as digging buckets, crushing hammers, and hydraulic shears. It is applied in multiple fields such as open-pit coal mines, tunnel excavation and contour correction, channel groove milling, asphalt concrete pavement milling, rock permafrost milling, and tree root milling. The milling and excavating machine provides a new construction method for tunnel excavation.

Features of XW milling and excavation machine:

1. Wide range of milling and excavation;

2. Low vibration and low noise;

3. Accurately control construction;

4. The material excavated by milling has a small and uniform particle size, which can be directly used as backfill material;

5. Good safety;

6. Simple structure and convenient use.

By integrating the natural working environment and setting up the energy of the mechanical equipment, the ER250 standard road hydraulic milling and digging machine is selected to carry out the excavation work of tunnel construction. The selected milling and cutting method is on the Carter 312D hydraulic excavator, the hydraulic system control circuit of hydraulic hammer or hydraulic shear is used to assemble the ER250 milling and digging machine, and the milling and digging head of the milling and digging machine is used to drill the rock formation at high speed.

In order to meet the requirements of the design scheme, it can effectively reduce the oscillation of surrounding rock caused by excavation, manipulate the overcut and undercut, improve the quality and safety factor of excavation, and reduce the labor efficiency of actual employees.

According to the construction plan of air shaft foundation pit and its cross safety passage and section line, the construction shall be carried out after the longitudinal hydraulic milling and digging machine is successfully assembled on the excavator.

First of all, the excavation of the foundation pit of the intermediate air shaft and the excavation of the tunnel are carried out. The key applications include the milling and digging of the foundation pit of the air shaft, the digging in the tunnel, including the sharpening of the tunnel wheel corridor to carry out the underexcavation and renovation, the release of the prominent loose surrounding rock after the crushing of the tunnel arch excavator, and the construction of the horse head gate of the cross safety channel in the deep foundation pit excavation link.
