Yanbian excavation and modification hydraulic rock

What are the different types of rock excavation applications?

Rock excavation applications in the construction industry include trenching, underwater dredging or excavation for foundations. In addition, you can successfully use hydraulic attachments for excavation of frozen ground where a standard bucket is too weak. The ease of excavating depends on many properties of the rock material and rock mass.

Why does a hydraulic breaker eficiency affect rock excavation?

The main factor of a hydraulic breaker’s eficiency is the stability, and therefore better rock exca-vation is possible when the balance between the carrier weight (Wc) and hammer weight (Wh) is stable, as shown in Figure 1.

Are hydraulic breaker or drum cutter a good alternative for rock excavation?

The performance capacity and adaptability of heavy-duty hydraulic breakers or drum cutters make them an interesting alternative for rock excavation. Use of hydraulic breaker or drum cutter is more economical, than use of a drill rig and explosives. Heavily fissured rock sometimes makes it difficult to drill and blast.

What is rock excavation?

Rock excavation is done for multiple purposes or applications. In open pit mines, it extracts metallic or non-metallic deposits and bedded deposits like coal or in quarries; rock excavation extracts building materials like aggregates or stones in the dimension stone industry.

Why are hydraulic rock breakers used in excavating rock masses?

The demand for the usage of hydraulic rock breakers in excavating rock masses has increased recently for environmental and economic reasons. The conventional method (i.e., drill and blasting technique) has many restrictions due to envi-ronmental aspects.

What factors determine the duration of a rock mass excavation?

The breaking rate or the productivity is the most reli-able factor determining the duration which is taken for the rock mass excavation in the first place. These param-eters are used in the selection of the optimum size of rock breakers to fulfil the objective or the targeted time frame.
