10 Questions You Should to Know about Mining Machinery

View Details

Humans have been mining for thousands of years, even in pre-historic times! Mining accidents have claimed hundreds and thousands of lives since the early 20th century. Because of that, safety has always been a concern. Since then, governments and institutions have been looking for ways to keep miners safe.

Mining is the excavation of minerals and materials from the earth. Each mine site has its own unique hazards that are extremely dangerous to workers. Mining often involves heavy machinery, industrial vehicles, large power tools, hazardous chemicals, and much more. Miners are at the risk of falling, experiencing hearing loss, breathing in dust, and are usually working in dark confined spaces.

Topics covered:
It is important for employers to understand the dangers of mining so they can adequately keep their workers safe. Read through our answers to some of the most commonly asked questions when it comes to mining safety. Some of the topics that we will be covering include:

• Mining PPE: PPE, while it should be the last resort in keeping people safe, is a life saver in these types of hazardous environments. We will go through some of the most common articles of PPE that miners will likely need while performing tasks.
• Visual communication: Visual communication is everything in these kinds of environments. They not only help alert workers of dangerous conditions; they also help to remind employees of the proper ways to prevent accidents or at least remind them of using the right PPE.
• Common hazards: Mines are rife with hazards. Not only will we go over which ones are especially prevalent, but we will also cover the precautions that employers must take to protect their employees from them.

Mining safety is incredibly important. The Mine Safety and Health Administration works hard to provide regulations that aim to prevent disaster and lower mortality rates. Learn all about mining safety here with our Q&A section.

The mining industry is highly dependent on water. Interactions of the mining industry with water resources are highly complex and site-specific, with potential impacts to both hydrology and water quality occurring at all stages of a mine&#;s life. The water requirements and impacts change significantly throughout all stages of a mines life&#;s:

• pre-development 

• development 

• operation 

• rehabilitation 

• post-closure 

A range of water management approaches are employed by the industry to mitigate the risks of adverse water impacts occurring. Mining occurs across the full spectrum of hydrological contents, from the arid regions of central Australia through the tropics and to the sub-arctic conditions of Canada and Finland. The local climate and hydrology dictates infrastructure requirements at mining operations and has a profound influence on the nature of water related risks faced by mines and nearby communities, ecosystems and industry.

Q1) Why do mines need water? 

Mining is a very water-intensive industry. In mineral processing, slurry transport, dust suppression, fire control, flotation, grinding, screening, dust scrubbing, wash water, pump gland seal water, reagent mixing, cooling of equipment, and to meet the water needs of employees. Mining operations need water to process ore and run camp operations.

Zoneding machine are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

Q2) How does mining affect water?

The development of a mining operation can significantly alter the natural flows and quality of water in a region. Large scale movement of material and the development of mining voids can result in significant alterations to natural water flow pathways through an area. When mining takes place in areas where water is scarce, mine water consumption can severely impact local supplies. 

Q3) Does mining affect ground water?

Infiltration of groundwater into mine voids can significant and so active dewater of aquifers is often required to lower the surrounding groundwater table and reduce infiltration rates. Acid rock drainage, leaks from tailings or waste rock impoundments, or direct disposal of tailings into waterways can additionally contaminate surface and groundwater. 

Are environmental regulations, health and safety concerns or potential profit loss a concern right now?

Q4) What is water balance at a mine site?

The overall water balance of a mine is either water positive or water negative. A water positive mine site, during accumulates water in dams, ponds and mine voids during periods of high rainfall and low evaporation. On a water negative mine site, evaporation rates are sufficient to prevent water accumulation. A variation in local hydrology results in fluctuation between the two extremes.

Q5) What are the sources of water in mines?

The sources of water in mines include atmospheric water, surface water, groundwater (renewable and fossil) and sea water. On the actual mine site, they may be dedicated ponds and dams for storing raw water, recycled process water, seepage containment, evaporation ponds and fire water. 

Q6) How much of the water used in mining is typically recycled?

Modern mines often recycle all available water. For example, in Canada, metal mines recycle a higher percentage of water than any other industry. The high rate of water recycling means water consumption depends not on the amount of water required for individual unit operations, but the amount of water lost to permanent water sinks, such as evaporation, seepage or retention in the concentrate or tailings material.

Q7) How can water conservation be improved in mining?

When conservation of water is a concern, mines are increasingly seeking to reduce evaporation rates from water stores using covers, shading, or even floating solar panels. To reduce water losses for dust suppression on the mine roads, the water can be superactivated to make water work. This effort reduces road dust suppression water requirements by over 50%. 

Q8) How much water does mining use in Australia?

According to the Australian Bureau of Statistics (ABS), in -20 the Australian mining sector extracted 1,100 gigalitres of water &#; 1,100,000,000,000 litres. A mine water truck uses more water in one trip than each of us consumes in a year, just for dust suppression. Consider how much water mines need to source and use on-site annually.

Q9) Can mining affect water resources?

There are major long-term trends within the mining industry, such as increasing mine size, declining ore grades, and increases in overburden and waste material. These trends place upwards pressure on water use requirements and the potential for water quality impacts to occur.

Q10) Does mining dust suppression use a lot of water?

Yes. For example, a CAT 777G water truck carries 76,000 litres of water. A typical household uses around 200 litres of drinking water per person per day based on Lower Hunter Region&#;s Hunter Water Corporation. That&#;s 73,000 litres per person annually. A mine water truck uses more water in one trip than each of us consumes in a year for dust suppression. 

Water &#; a precious resource. GRT focuses on these 2 key elements &#; water quantity and water quality. Saving water through high tech dust control solutions has long been the focus of the company. Use of water alone dust suppresion is not sufficient owing to high surface tension of water on interaction with hydrophobic dust particles. GRT&#;s products reduce the surface tension of water therefore reducing the water required and improving dust control sustenance compared to water alone. Our commitment to managing water has expanded into the creation of cutting edge technologies to save directly save water and to also improve stored/retained water quality. Along with our dust and erosion control products, GRT&#;s range of direct water management technologies are focussed on improving and conserving this precious resource.
