Hydraulic hose failure in mining can stop your machines. This can slow down your whole work site. You face risks like air and water contamination. There are also extreme temperature changes, low fluid levels, and human mistakes. The table below shows the most common causes:
| Cause | Explanation |
|---|---|
| Air and Water Contamination | This is the main reason for hydraulic failures. It causes 80-90% of problems. It happens from broken pumps, system leaks, and temperature changes. |
| Temperature Problems | Very hot or cold temperatures can change the fluid. The fluid can get too thin or too thick. This can hurt lubrication and cause leaks. |
| Fluid Levels and Quality | Low fluid levels and bad filters can let air in. This can also cause temperature problems. |
| Human Error | If people install or fix things wrong, it can cause big problems in the hydraulic system. |
You need Hydraulic Hose Solutions that can handle tough conditions. They must be reliable. Kingdaflex gives you proven quality. They have global certifications and advanced technology. These work for your mining drills, excavators, and roof supports.
Downtime Risk in Mining Operations

Productivity Loss from Hose Failure
If a hydraulic hose breaks, it is not just a quick fix. Your machines stop working. This means you lose money fast. For example, if you make $10,000 each hour, four hours stopped means $40,000 lost. These losses can hurt your business. You might miss delivery dates. This can make clients unhappy.
A broken hose does more than stop work. It can be dangerous for workers. Fluid leaks can make people slip or fall. Sometimes, leaks can even start fires. Fixing the hose quickly costs more money. You still pay workers even when machines are off. Emergency fixes cost more than planned repairs. All these things lower how much work gets done.
Cost of Maintenance vs. Prevention
Skipping regular checks may seem cheaper, but it is not. Emergency repairs and sudden stops cost much more. Here is what can happen if you wait too long:
- Machines do not work until you get a new hose.
- Leaks or bursts can cause spills and make things too hot.
- Emergency fixes cost more than regular checks.
- One broken hose can stop all your work and cause big losses.
If you have fewer breakdowns, you spend less fixing things. Checking hoses often helps you avoid big problems. It keeps your mining work going well. Using good hoses and regular checks protects your machines and your money.
Mining Hydraulic Hose Challenges

Pressure and Abrasion Resistance
Mining work puts a lot of pressure on hoses. Hoses must handle heavy loads and sudden changes. Six-spiral wire reinforced hoses, like SAE 100R15, are very strong. They can take hard hits and rough use. You also need a tough cover and a spiral guard. This keeps hoses safe from rocks and sharp things. Picking hoses that handle more pressure helps stop sudden breaks and stops.
Extreme Temperatures and Chemicals
Mining can be very hot or very cold. Heat can make hoses crack and leak. Cold can make hoses stiff and easy to break. You need hoses that work in many temperatures. Some hoses work up to 260°C (500°F). They are tested to make sure they do not leak or break under heat. Look for hoses that meet ISO 18752 and API Spec 7K. These hoses work well in tough places.
- High-temperature hoses work from 150°C (302°F) to 260°C (500°F)

Roof Support Hydraulic Hose Solutions
Load-Bearing and Safety
Roof support systems in mining need strong hoses. These hoses must hold heavy loads and keep workers safe. Longwall mining uses high-pressure hydraulic lines. The hoses work with petroleum-based or water emulsion fluids. Two wire braid hoses are common because they handle both steady and changing pressure. The hydraulic circuit inside roof supports stays steady most of the time. This lets hoses handle higher pressure without breaking.
You should pick hoses that meet EN 853 2SN standards. These rules say the hose’s working pressure is about one part, and the burst pressure is two and a half parts. This helps you know the hose will not burst during normal use. EN rules set the burst pressure, so you have a good safety margin.
- High-pressure lines are used for longwall mining and roof supports.
- Hoses work with petroleum-based and water emulsion fluids.
