The construction and reinforcement of tunnels in underground mining is a process that uses modern equipment and tools available in the market today. However in mine-preparation projects by "Block or Panel Caving" with tunnels smaller than 4m x 4m, standard machinery cannot be used since it does not have enough space to operate and maintain the same productivity level. Mining Equipment Manufacturers: Construction and mining equipment cover a variety of machinery such as hydraulic excavators, wheel loaders, backhoe loaders, bulldozers, dump trucks, tippers, graders, pavers, asphalt drum / wet mix plants, breakers, vibratory compactors, cranes, forklifts, dozers, off-highway dumpers (20T to 170T), drills, scrapers, motor graders, rope shovels etc.

1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Let's follow a rock through a crushing cycle to see what variables will have to be controlled. First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher "breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can't fall through will

Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense comprises extraction of any resource (e.g. petroleum, natural gas, salt or even water) from the earth. Mining of rock and metals has been done since prehistoric times.
