How to carry out face rock shipment?

Loading the rock that has been blasted into the mining face into the mining surface is the shipping operation of the rock, also known as the slag. It is a relatively heavy work, accounting for 40%~50% of the tunneling time.

The most used loading equipment in the roadway excavation is the bucket type rock loader and the mine car, as shown in Figure 6-8. The rock loader is powered by gas, and it is also powered by electricity. When the rock loader moves forward, the bucket is inserted into the rock pile to shovel the rock; after the shovel is full, the bucket is lifted and turned backwards to be loaded into the rear mine car; then the bucket is dropped and shovel again. After a mine car is full, it is removed and transferred to another mine car to continue loading the rock.

Since the shunting is rather cumbersome and time consuming, in recent years there have been some equipments that solve the problem of roadway shunting and shunting, such as bucket loaders and shuttle mine cars. The former uses the bucket that can be lifted and moved up and down on the mine car, accepts the rock unloaded by the loader bucket, and sends it to the scheduled mine car for unloading until the entire rock that has been blasted is installed; In fact, it is a large-capacity mine car equipped with a transport aircraft, and the mine car is gradually filled by the movement of the transport aircraft.

In addition, the use of tire-type self-equipment, such as a scraper, to complete the loading, unloading, and transportation work can greatly improve the loading speed and effect.

Turning Conveyor

The sector belt of the turning belt conveyor is equipped with a special anti deviation roller (POM is added to the bearing) or high-frequency welding guide ribs are welded on the outside of the conveyor belt to make the conveyor belt run in a special guide rail. The roller adopts a special conical rubber wrapping roller. The turning Belt Conveyor can transport a wide variety of materials, not only various bulk materials, but also various cartons, packaging bags and other pieces of goods with small single weight, which are widely used.
