Traditional surveying techniques are being enhanced by new technologies like 3D laser scanning. Advances such as this allow us to capture the geometry of terrain or objects with high precision through the emission of laser pulses.

Its operation is based on the principle of active remote sensing, which involves emitting radiation that is then analyzed by various sensors receiving the reflected signals to determine distances. In the construction and architecture sectors, where projects seek to optimize time, this technology improves efficiency, increases accuracy, and provides a fast and detailed alternative to conventional methods.

SPEED WITH PRECISE MEASUREMENTS

Compared to conventional surveying, which relies on equipment like total stations and high-precision GPS while also being prone to human error, 3D laser scanning enables faster surveys with a higher density of data points and minimal interference. While traditional techniques require point-by-point surveying, laser scanning generates clouds of millions of points in minutes, resulting in a highly detailed and precise three-dimensional representation. Additionally, it reduces the likelihood of human errors and minimizes the need to return to the site for additional data collection.

BETTER DATA PROCESSING

When it comes to data processing and its conversion into models, the benefits continue. The results obtained through 3D laser scanning optimize data processing, enabling the creation of dense digital models (more complete point clouds) of the terrain and three-dimensional representations ready for analysis in specialized software in a shorter time.

In other words, the workflow is streamlined—from data collection to processing and model generation. Every step leads to improved efficiency, cost savings, and time reduction, prompting us to rethink work methods and always offer the best techniques to benefit your company.

In the mining sector, surveying is a key component throughout the entire production process—from exploration, during extraction, and finally in mine closure—due to the benefits it provides in achieving efficient resource management in the extractive industry.

Thanks to the work of companies like Acero Estudio and its surveying services, mining companies can:

• Accurately calculate the extracted and processed tonnage.
• Recalculate proven reserves and optimize processes.
• Effectively plan the continuity of their operations.
• Reduce risks and comply with environmental and safety regulations.

What Equipment Do We Use in Mining Surveying?

While traditional tools like levels and total stations are always useful, the mining industry requires modern tools and cutting-edge technology. For this reason, at Acero Estudio, we focus on this sector by employing UAV (Unmanned Aerial Vehicles) or advanced drones equipped with high-resolution sensors. Using these innovative tools allows us to obtain detailed and reliable information in less time and with greater safety.

Drone technology is a key resource in mining surveying, as it significantly improves process efficiency and minimizes risks associated with working in unstable or hard-to-access terrains.

Advantages of Using Drones in Mining Surveying

• Enhanced Safety: Drones enable surveyors to take measurements in unstable or hard-to-reach areas without exposing themselves to danger.
• Faster Data Collection: Thanks to their advanced sensors, drones capture topographic information much faster than traditional surveying techniques.
• Quick 3D Model Generation: The data collected allows for the rapid creation of precise three-dimensional terrain models, facilitating planning and decision-making.

Additionally, UAV drone technology enables us to project roads and new explorations based on the terrain’s characteristics. This is crucial in an industry where a significant portion of investment is dedicated to finding new deposits. Aerial surveying helps optimize access routes, assess project feasibility, and improve exploration logistics.

Finally, topographic information is essential for mine closure operations. Conducting topographic evaluations throughout the entire mining process is vital to prevent leaving areas exposed to landslides or floods. A proper terrain study during the closure phase helps mitigate environmental risks and ensures post-exploitation land stability.

Since it is currently the rainy season along the Latin American coast, this article is highly relevant and well-contextualized for the first three months of the year.

Among the lesser-explored functions of topography is that it enhances the understanding of soils and their stability characteristics. This knowledge is essential for accurately calculating the volumes of material carried by rain during specific periods of rainy years.

The proper evaluation of these phenomena allows us to understand soil behavior in response to water erosivity and its sediment transport capacity, which directly impacts the design and maintenance of natural and artificial channels.

To estimate sediment contribution in basins, the empirical Gavrilovic model (Gavrilovic 1959, 1988; Zemljic 1971) is employed, widely used in hydrology and geotechnical studies. This model enables the calculation of annual sediment production by considering variables such as precipitation erosivity, geological and edaphological characteristics of the terrain, land use, and slope.

Thanks to this methodology, it is possible to obtain a reliable estimate of the amount of sediment transported by waterways during intense rainfall events, contributing to better planning of mitigation and erosion control measures.

These types of studies are fundamental for improving knowledge of alluvial flows, allowing for the reduction of their impact and risks on urban and transportation infrastructure. The accumulation of sediments in channels and reservoirs can cause blockages, reduce storage capacity, and increase the risk of flooding. Therefore, the application of topographic techniques and mathematical modeling is key in designing preventive and corrective solutions for efficient water resource management and the protection of hydraulic structures.

Topography, like any discipline, demands expertise and knowledge to avoid errors and achieve optimal results. In our field, accuracy is critical, as even minor errors can accumulate and lead to significant negative consequences in engineering projects if not detected in time.

The main types of errors in topography are systematic errors and accidental errors. Let’s understand how they arise and how to prevent them to ensure the quality of the results.

Systematic Errors

These are deviations that occur due to equipment malfunctions, incorrect calibrations, improper procedures, or environmental factors. Systematic errors tend to repeat under the same conditions and, if not corrected, can lead to consistently inaccurate results.

Examples of systematic errors:

• Uncalibrated total stations, damaged leveling instruments, etc.
• Environmental factors such as light, metal expansion due to heat, or fog affecting instrument readings.

Accidental Errors

These are deviations caused by unpredictable variables such as human error or accidental instrument movements. While they are unavoidable to some extent, these errors are typically minor when proper procedures are followed.

Examples of accidental errors in topography:

• Instrument reading errors due to operator distraction or carelessness.
• Vibrations in the terrain caused by machinery or other external factors.

How Do We Prevent These Errors?

As a specialized topography company, we implement procedures to minimize errors and ensure the reliability of our work. Below are the measures we take:

To Prevent Systematic Errors:

• Regular maintenance of equipment: We have preventive maintenance plans to ensure all instruments function perfectly.
• Calibration and verification: Total stations and levels are calibrated and checked before any project.
• Evaluation of atmospheric corrections: Adjustments are made for environmental factors, such as material expansion on hot days.
• Deviation tests: These tests are conducted to identify potential systematic errors.

To Prevent Accidental Errors:

• Continuous training: We provide regular training and updates to our personnel.
• Advanced technology: Our tools feature integrated viewers and systems to reduce common errors.
• Comparative measurements: We conduct multiple measurements to identify and eliminate inconsistencies.

The Gauss Curve and Its Application in Topography

The distribution curve, or Gauss curve, helps identify potential errors by analyzing deviations in the data. It allows us to distinguish between systematic and accidental errors effectively.

This statistical tool enables informed decisions about the quality of the collected data and the implementation of corrections when necessary.
