ACARA 5 PEMETAAN TAMBANG BAWAH TANAH DENGAN TOTAL STATION TOPCON GTS 1000

Introduction

In this tutorial, we will explore the process of underground mine mapping using the Topcon GTS 1000 total station. This technique is essential for accurate surveying in mining operations, allowing for precise measurements and layout plans. Let's break down the steps to make this process clear and straightforward.

Step 1: Prepare Your Equipment

Before heading to the field, ensure you have all necessary equipment ready to go:

• Total Station: Make sure your Topcon GTS 1000 is fully charged and calibrated.
• Tripod: Set up a sturdy tripod to support the total station.
• Measuring Tape: Useful for additional measurements and verification.
• Safety Gear: Always wear appropriate safety equipment when working in mining areas.

Step 2: Set Up the Total Station

Follow these steps to properly set up your total station:

1. Place the tripod on a stable surface.
2. Adjust the tripod legs to ensure it is level.
3. Attach the total station securely to the tripod.
4. Use the built-in level to confirm the total station is perfectly horizontal.

Step 3: Input Reference Points

Input the necessary reference points into the total station:

• Coordinate System: Define the coordinate system you’ll be using for mapping.
• Control Points: Enter the control points that will serve as references for your survey.

Step 4: Conduct the Survey

Now you’re ready to start mapping:

1. Aim the total station at the first point you want to measure.
2. Record the angle and distance measurements.
3. Move to the next point and repeat the measurement process.
4. Ensure you have a clear line of sight to all points to avoid errors.

Step 5: Data Collection and Analysis

After completing the measurements, it’s time to collect and analyze your data:

• Download Data: Transfer the data from the total station to your computer.
• Software Analysis: Use mapping software to analyze and visualize the data.
• Check Accuracy: Verify the accuracy of your measurements with known benchmarks.

Step 6: Create Mapping Plans

Using the analyzed data, create detailed mapping plans:

• Draft Maps: Use the software to draft maps showing underground features.
• Highlight Key Areas: Mark important areas such as ore deposits and safety zones.

Conclusion

By following these steps, you can effectively map underground mines using the Topcon GTS 1000 total station. Always ensure your equipment is well-prepared, and take the time to verify your measurements for the best results. With practice, you'll become proficient in underground surveying, leading to safer and more efficient mining operations.
