# What is Stockpile Measurement?
Stockpile measurement refers to the process of determining the size, volume, or weight of a bulk material stockpile. Across industries dealing with large quantities of goods, stockpiles are commonly accumulated at specialized storage facilities designed to house these materials. These piles are typically deposited by trucks, maneuvered by bulldozers, and managed by workers. But how do managers and staff know precisely what they're working with?
In the past, workers relied on manual estimation or GPS services, which could only provide approximate measurements within a certain range.
However, recent advancements in stockpile measurement techniques now allow businesses of all kinds to achieve hyper-accurate measurements, significantly boosting productivity and reducing costs.
## Why Is Stockpile Measurement Important?
Accurate stockpile volume measurements can benefit companies across numerous industries. Whether handling coal, ores, fertilizers, or industrial dust, precise stockpile calculations can help businesses cut costs and operate more efficiently.
### Increased Profitability and Efficiency
If workers are merely guessing the quantity of product within a stockpile, it’s inevitable that some materials will go to waste. Traditional measurement methods have limitations, and for every pound of product that isn't accurately measured, potential profits may be lost.
With advanced stockpile measurement solutions, businesses can reduce excess inventory and the associated costs. Stockpile calculations can also help businesses decide when to reorder or resume mining activities. This planning enables companies to schedule machine downtime and better allocate workers and contractors, saving on maintenance, repair, and labor costs.
Moreover, precise stockpile measurements improve strategic decision-making, leading to increased productivity and profitability. Investing in upgraded stockpile measurement tools proves to be a worthwhile return on investment.
### Valuable Data for Decision-Making
When gathered effectively using modern technology, raw stockpile measurement data can support businesses in various ways. We’ve seen how stockpile calculations can enhance internal efficiency, but they also assist companies in tax savings, loan applications, and other financial assistance opportunities.
The more accurate a company’s stockpile measurements are, the easier it becomes to leverage that data for external purposes. Using stockpile volume calculation techniques, businesses can transparently assess their inventory for financial reports and excise duties. This data can also be used to secure loans from banks and address other financial needs.
In essence, the more accurate your stockpile volume data is, the easier it is to use that data strategically to your advantage.
### Compliance with Regulatory Requirements
Stockpile measurements can also help businesses adhere to specific regulatory requirements. For instance, the EU Emissions Trading System necessitates businesses to conduct mass balances to calculate CO2 emissions, a task made simpler with precise stockpile management.
The key here lies not just in accuracy but transparency as well. Regulators and compliance boards can trust data that has been measured to the inch, ensuring that the information hasn’t been altered or estimated. In this way, stockpile volumetry benefits both the business and regulatory bodies by enabling faster and more efficient operations.
### Enhancing Worker Safety
Stockpile measurement can minimize risks for workers by ensuring they are only mining, collecting, or retrieving materials when necessary. If no ore is wasted, workers spend less time in potentially hazardous environments, reducing the likelihood of accidents.
Increased efficiency from stockpile calculations not only boosts profits but improves worker satisfaction. Additionally, modern stockpile measurement technologies, like drones, have replaced traditional tools in several industries, creating an extra layer of protection between workers and hazardous materials.
Take, for example, the 3D fly-through of stockpiles at a salt mine. This visualization was created using LiDAR data collected by the Elios 3 drone—read the case study to learn more.
Large stockpiles of dust, stone, or fertilizer can pose dangers to human workers, often containing hidden air pockets that could lead to accidents. However, with a UAV or other robotic measurement tool, the risks are virtually eliminated.
Finally, proper stockpile management reduces downtime and maintenance costs, further decreasing the likelihood of workers putting themselves in risky situations during repairs.
## Which Industries Utilize Stockpile Measurement?
### Aggregates
An aggregate is a construction material made from natural resources like sand, gravel, and crushed stone. When mixed with a binding agent such as water, asphalt, or cement, these materials form different types of concrete used in roads, bridges, and parking lots.
Managing aggregates presents challenges due to their varying sizes and compositions. Stockpile measurement ensures materials are used efficiently and prevents cross-segregation of different mixes. It’s also critical for protecting stockpiles from degradation like water damage or erosion.
### Construction
Construction suppliers dealing in materials like sand, dirt, or wood chips rely on daily stockpile calculations to manage inventory and assign workers. This information is also used to plan hauling routes, improving worker safety and satisfaction by giving dozer and crane operators clear guidance on material availability.
### Mining
Mining and ore management heavily depend on stockpile measurement solutions. Technologies like mining drones enable up-to-the-inch accuracy in measuring inventories of materials like iron ore. These tools also enhance worker safety by eliminating the need for manual measurement of potentially dangerous stockpiles.
### Recycling
Accurate stockpile data is crucial in recycling and waste management. A case study by Flyability showed that a recycling company increased the accuracy of its inventory estimates by over 200% using drone technology. This allowed the company to better predict recycling timelines, maintain optimal stockpile levels, and comply with storage regulations.
### Shipping and Ports
Ports and shipping centers are among the most common locations for stockpile management. Whether managing aggregates, ore, chemicals, or agricultural products, constant supervision and measurement are essential. Even slight variations in data can lead to significant losses in fuel, time, or money.
## Stockpile Measurement Methods
Stockpile volume can be calculated using various methods, each offering different levels of accuracy and applicability. Let’s explore some of the most common approaches:
### Manual Measurement
Traditional manual methods are the least accurate and are now largely replaced by modern solutions. However, if manual methods must be used, options include walking wheels, measuring by truckload, or visual estimation. These methods are prone to inconsistencies and inaccuracies.
### Smartphone Applications
For budget-conscious businesses, smartphones can serve as effective data collection tools. Paired with appropriate software, these apps can deliver surprisingly accurate results within 24 hours. While the accuracy may not match high-end solutions, it offers a cost-effective alternative for businesses that can tolerate a slightly wider margin of error.
### Photogrammetry
Photogrammetry involves capturing thousands of images to create detailed 3D models. This method is particularly useful for stockpile measurement, providing highly accurate data. However, it can be costly and may require professional operators, making it ideal for businesses needing frequent updates.
### LiDAR
LiDAR uses lasers to create precise 3D maps. Similar to photogrammetry, it offers high accuracy, especially in low-light conditions. However, LiDAR systems are expensive and best suited for specific scenarios requiring high precision.
## Drones for Stockpile Measurement
Drones are one of the best tools for collecting stockpile measurement data, as they can carry cameras, photogrammetry sensors, or LiDAR scanners. Indoor stockpile measurement often benefits from drones like the Elios 3, designed for dark and dusty environments.
For outdoor measurements, drones with long battery life or multi-flight capabilities are preferable. They can cover large areas quickly and efficiently, offering unparalleled speed, accuracy, and safety compared to traditional methods.
