Hose for Mining Applications: Best Practices ...

Missouri is home to countless rock quarries and coal mines as well as strip and underground mines and the businesses that operate in this space require specialized hydraulic and industrial hose solutions. You need a partner you can trust.  

For more information, please visit HT-HYDRAULICS.

We understand the supply needs of our mining customers in the Greater St. Louis region and beyond and take the time to get to know your business.  

Here&#;s why that matters: 

The hydraulic and industrial hoses commonly used in surface and underground mining have unique needs based on each application. Choosing the wrong hose can wind up costing you time and money. 

Here are two examples:  

• Some hoses may run several miles long and involve multiple couplings at various connection points, increasing the potential for leak points.  
• Some applications require a hose that can stand up to wild temperature fluctuations or face a devastating breakdown in the hose construction.  

Any miscalculations on these hose assembly needs can result in dangerous and costly hose failure.  

If your goal is to better manage costs, mitigate risk as well as protect people and equipment at every stage of your mining operation, we can help with expert guidance every step of the way.   

What is the difference between surface mining and underground mining operations? 

What is surface mining? 

Surface mining is a method of extracting minerals near the surface of the Earth. The four most common types of surface mining are coal mining, open-pit mining, strip mining and quarrying. Surface mining is often used to uncover materials that include:  

• Sand, gravel, crushed rock 
• Marble, granite, limestone, sandstone and slate 
• Coal, phosphate and other minerals 

Facts about Surface Mining:  

• Surface mining typically requires larger hose and fitting coverage than underground mines.  
• The equipment used &#; scrapers, dozers, haul trucks, water trucks, hydraulic shovels and drill rigs &#; all have similar hydraulic needs and may use hoses between ¼ inch to 4-inch in diameter.   
• Most hydraulic hoses and couplings used in mining applications must meet or exceed the Mine Safety and Health Association (MSHA) requirements. 
• Some operations require specialized lines premade by the manufacturer to cover any warranty issues on new equipment. 

What is underground mining? 

Underground mining is different than surface mining in that when any ore body lies a considerable distance below the surface, the amount of waste that has to be removed to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. 

Underground mining typically incurs higher costs due to:   

• Size of underground mining equipment  
• Limitations of ground conditions, ore body geometry 
• Limited access 
• Increased labor hours 

Facts about Underground Mining:  

• Hoses can have high-pressure requirements between 3,000 to 5,000 psi.  
• Hydraulic hoses may be used in equipment to hold up the roof of a mine. 
• Monorails and other systems used in the process may rely on hydraulic hose systems.

Note: While hose needs may be similar across mining applications, it&#;s important to remember all hoses are not the same. For instance, a common cause of failure is using the wrong hoses interchangeably. For that reason, braided hoses and spiral hoses should never be assembled together.  

Additionally, hoses can come in various pressure ranges &#; low, medium, high and ultra-high pressure ranges. So, take care when selecting the right hose to meet those demands.

How are the supply needs of the mining industry different from other industries?  

Mining is tough on equipment and components. 

The mining industry is different than most industries due to the conditions of the environment and landscape. Extreme temperatures, rugged terrain, exposure to dirt, sand, wind and debris and even routine handling can quickly break down hose assembly components.  

This is significantly different from industrial facilities where operations managers can implement solutions to mitigate wear and tear, such as temperature control, routine cleaning and proper storage.  

Due to the harsh environment, mining operations require the use of high-quality and durable hose equipment. What&#;s more, because most mining operations occur in remote locations far away from supply houses, businesses need reliable access to inventory like high-pressure hose lines, fittings and other components required for their assemblies.  

Did you know? Superior Industrial Supply can place an onsite hydraulic hose crimping machine, inventory and protective storage on your worksite to reduce hose-related downtime, maintain access to critical spares and extend the service life of your hoses. We also have the widest selection of specialty hoses and fittings your mining operation needs.  

Costly Implications of Failed Hose Systems 

Mining often requires multiple operations to occur simultaneously and if one area goes down many other areas will be compromised. It&#;s another reason to seek expert advice when creating your hose assembly. 

Not only can a downed line halt production, but it can also have devastating impacts on people and property including burns from flammable or hazardous material, slip-and-fall accidents, explosions or even punctures and lacerations from high-pressure hose lines.   

Other impacts of hose failure include:

What Hoses are Right for Mining Operations?  

Hoses are an integral part of the mining process and have evolved over decades to improve production rates and worker safety.  

But choosing the right hose lines can make or break your productivity, safety and profitability. That&#;s why we only carry the best hoses, fitting and connectors like those from Danfoss Power Solutions (formerly Eaton). You can rely on us for trusted industrial and hydraulic hose solutions that meet or exceed the Mine Safety and Health Association (MSHA) requirements.   

&#;To reduce hose failure from using the wrong hose, some mining businesses may consider using a standardized hose system, either braided or spiral, for consistency across operations. This consistency can eliminate unnecessary inventory, save money on purchases and reduce mix-match hose systems. &#;

Blasting Operations Require Specialty Hose Solutions 

For blasting operations using ANFO, an industrial explosive which stands for ammonium nitrate/fuel oil, we recommend two hoses in particular.  

• The Series K Anti-Static Blasting Tubing from Kuriyama is ideal for the loading of ANFO blasting agents in mining and construction applications.  
• The Industrial H from Danfoss is ideal for water and diluted pesticide transfer, water suction and discharge from the ANFO truck to the blasting site.  

When choosing the right hose, it&#;s important to consider the pressure rating the application requires as well as the configuration of the hose end (what fittings you&#;ll need). This is a major reason why we recommend choosing one brand of hose lines so that you can ensure compatibility.  

&#;Rather than selecting a hose based on cost alone, be sure to think about the quality, durability and service life of your hose assembly. There&#;s nothing worse than being out in the middle of nowhere and a downed line halts your entire operation, especially when it could have been prevented.&#;

11 Common Causes of Hose Failure (Inspection Checklist Included) 

Hoses are the weakest link in your system and have limited-service lives, requiring regular inspections, maintenance and replacement for safe and reliable operation. We can help you plan for, assemble and service your hose assemblies to maximize their life and performance.  

Top 11 Reasons Why Hoses Fail in Mining Operations 

1. Abrasion on Surface Area 
2. Improper Assembly and Fittings  
3. Improper Routing 
4. Tube Erosion 
5. Pressure Surges 
6. Fluid Incompatibility 
7. Improper Bend Radius 
8. Wrong Insertion Depth 
9. Extreme Operating Temperatures 
10. Chemical Exposure 
11. Dry Air

Did you know? Abrasion is the most common cause of hose failure &#; rubbing against other components or equipment (Machine Design). Fortunately, hose coverings can minimize the likelihood of abrasions without impacting the bend radius. Some options include:  

• Steel or flat spring guarding  
• Plastic guarding  
• Abrasion-resistant sleeves 

These are just a few factors that can impact hose performance. Mining operators should be aware of the differences and limitations of their hose systems to prevent injury or failure from these missteps. And it&#;s a great reason to include regular hose maintenance and replacement training as part of your program.

The ferrule used with two-piece fittings allows greater flexibility in hose selection and connection, including 1SN, 2SN and multi-spiral hoses which allow for multiple two-piece fitting and ferrule options to accommodate the specific application.

Stainless 316 two-piece hose fittings are the best selection to ensure corrosion resistance and long service life, especially in chemical and offshore applications. In these critical applications where 316 stainless is used, the end user may require the hose fitting manufacturer provide material traceability.

Two-piece hose fittings are used for these critical and exceptionally high pressure applications, particularly when there is the possibility of extreme hose vibration and/or pressure surges. When severe conditions are present near the fitting components, two-piece hose connections are highly important for providing a powerful assembly of the fitting and hose.

In these high pressure applications the hose is sometimes inside/outside skived (or 2 skive), creating a metal to metal connection on both the inside and outside of the hose.
