Application In Mine Projection

After the underground mineral are mined, there maybe sudden or gradual collapses, and even some place will be changes of terrain. These are called as mining goaf. The mining golf have a big influence on people’s life and production. For traffic, it is more like a disaster, it can make hundreds kilometers of highway be broken, several collapse and deformation on the highway projections. It is serious threat to the driving on way.

Due to the process of mining goaf is slow and irregular, then before the collapse being stable, we have to take several years for maintenance and protection, until the collapse are stable, the traffic can be carried out again.

Corrugated steel structure is light weight structure, and it has a good deformation resistant performance, so for mining goaf, it is a good construction material. For a concrete structure, the uneven land subsidence will caused it broken easily, but corrugated steel structure shows a obvious advantages because of its flexible characteristic.

Difference applications on mining projections of corrugated steel structure

Water drainage system: On the process of mining, water drainage is a important step. The corrugated steel culvert is widely adopted for drainage culvert because of its big strength and anti corrosion ability.

Ventilation system: Steel corrugated culvert pipes can be used as natural ventilation pipelines to make sure the are in the mines. Some time as customer request, we drilling holes on the walls corrugated steel pipes for ventilation.

Protection of cables and machines: in mines, rolling stones occurs occasionally, it maybe cause a damage on mining facilities. Then the corrugated steel pipe can be used as a protection well to prevent the damage from rolling stones.

Safety cabin: some mines use corrugated steel structure to be a part of safety cabin becasue of its Its high strength and compressive performance.
