hydraulic hose used in coal mining

Uses for Hydraulic Hose - Mining Products

Hydraulic hose are used in a number of industries including coal mining, tunnel building, petroleum related processes and welding. They allow liquids to be able to transfer at very high pressure safely and securely in hazardous environments. Hose are made from high quality rubber and are heavily insulated which increases their durability whilst being able to direct fluids in at consistent rates essential for the

Hose Safety and Reliability in Mining Hydraulics ...

Longwall mining is an underground mining operation in which a large panel or block of coal spanning up to 1,500 ft across distances of two to three miles is extracted. Longwall mines are characterized by low ceilings and tight spaces in which workers must operate heavy machinery. Hydraulic-powered roof supports, also called shields, protect the working area of the mine by extending as a shearer cuts back and forth along the coal face. Once it is cut by the shearer, coal

Within a particular coal mining activity all of the hoses on the Komatsu haul trucks will be replaced after 8000 operating hours, approx. 15 months of continuous operation. When hydraulic hoses fail as a consequence of external factors that are largely uncontrollable they very often cause the single machine that has stopped to create backlogs in production or operation for lengthy periods.

How do hydraulics ensure safety in mining machinery?

18/12/2018  It goes without saying, hydraulics are explosion-proof by their very nature. Hydraulic machinery was pivotal in mining to ensure productivity was high while remaining safe. Modern hydraulics with electronic controls are able to be used in mining with no safety concern thanks to the advent of explosion-proof electrical components. These are coils and switches with sealed electrical

Hydraulic coal mining - Seddonville NZHistory, New ...

Mining using water (called hydraulic or hydro mining) was common in the West Coast goldfields, but was applied only slowly to the mining of coal. There are major advantages in coal mining, as water minimises dust as well as the risk of explosion and fire. Westport entrepreneur and engineer Tom Moynihan was associated with a number of mines in the Seddonville area from the 1920s onwards, and developed

Hydraulics in mining Queensland Mining Energy

The final process of mining uses hydraulic vehicles to place coal and minerals on conveyor belts using stacker reclaimers and coal loaders. In underground mining, the equipment is almost wholly hydraulic. Even the reinforcing concrete in the tunnels is sprayed on using hydraulics. Hydraulic power is involved in the whole mining process. Whilst there may be some debate over some of the recent ...

Investigations into the ageing of hydraulic flexible hose ...

The hoses' performance characteristics suffered considerably from use in the coal mines. After six months of use only about 14% of the minimum pulse number were attained on average; at the end of two years this value had further decreased to approx. 2%. The maximum service life of hose assemblies in the mining industry should be shorter than indicated in ZH 1/74 (four to six years). As a first
