Efficient Coal Pile Management Made Easy! SLDL6300 Laser Coal Inventory Instrument Empowers Overseas Clients with Efficient Warehouse Coal Pile Management

In the fields of coal mining, power generation, and bulk material storage, accurate coal pile volume measurement and safe, efficient transportation are core links in inventory management and production scheduling. Traditional measurement methods are time-consuming, labor-intensive, and prone to errors, while inadequate transportation monitoring often leads to safety hazards and efficiency losses. SOLIDAT's SLDL6300 Laserscan Laser Coal Inventory Instrument has successfully solved these pain points for overseas clients, achieving efficient, precise, and safe coal pile management.

Project Background

A large overseas coal storage and transportation enterprise has long faced challenges such as irregular coal pile shapes, large storage areas, and difficulty in accurate volume measurement. Traditional manual surveying and GPS estimation methods could not meet the enterprise's requirements for inventory accuracy and management efficiency. Meanwhile, the lack of comprehensive monitoring of the coal transportation belt system often resulted in equipment failures, material blockages, and even safety accidents, affecting the continuity of production. To address these issues, the enterprise introduced SOLIDAT's SLDL6300 Laserscan Laser Coal Inventory Instrument, aiming to upgrade the entire process of coal pile measurement and transportation monitoring.

Pain Point Analysis 

• Inaccurate Traditional Measurement: The complex surface slope changes of coal piles make it difficult for traditional methods to reflect the true shape, resulting in large measurement errors (often exceeding 5%), which affects inventory accounting and production planning.
• Low Operational Efficiency: Manual measurement requires multiple personnel to cooperate, taking several hours or even days to complete the measurement of a single large coal pile, with low efficiency and high labor costs.
• Insufficient Transportation Monitoring: The lack of real-time monitoring of the belt conveyor system leads to delayed detection of deviations, blockages, and tears, easily causing equipment damage and production interruptions.
• Disconnected Management Links: The separation of coal pile measurement data and belt transportation data makes it impossible to form a closed-loop management, affecting the overall operational efficiency of the enterprise.

Implementation Plan

The enterprise adopted SOLIDAT's SLDL6300 Laserscan Laser Coal Inventory Instrument, covering the entire process of coal pile measurement, data processing, and transportation monitoring.

Based on laser ranging and 3D modeling technology, the SLDL6300 achieves non-contact rapid data collection. It has a maximum measurement range of 450 meters and a measurement accuracy of less than 5 millimeters, with a scanning speed of up to 3 points per second. The operator can complete automatic scanning by simply rotating the telescope manually, and the data is directly stored in the memory. The supporting professional 3D modeling software can quickly process point cloud data, generate DTM models, and automatically calculate volume, area, and other spatial information. The equipment is compact (weighing only 5.3 kilograms) and can be operated by a single person, supporting multiple operation modes such as backpack, drone, and vehicle-mounted, adapting to different coal yard environments.

Operation Process

• Route Planning: Before scanning, conduct on-site exploration to formulate a snake-shaped scanning route, with an interval of no more than 20 meters between paths to ensure dense and clear point cloud collection. The start and end points of the route coincide to facilitate post-processing correction.
• Point Cloud Data Collection: Operators carry the SLDL6300 to scan according to the planned route. During the scanning process, they can real-time check the collection path, relative position, and point cloud effect through a mobile phone to avoid missed or repeated collection.
• Data Processing: Import the scanned point cloud data into the supporting software for modeling and analysis, automatically extract the coal pile, select the reference surface, and calculate the volume with one click to generate a PDF report including weight (input bulk density manually).
• Data Integration: Integrate the coal pile measurement data into the enterprise management platform to realize digital management and visual analysis of the entire process.

Data Results

After practical application, the SLDL6300 achieved a volume measurement error of less than 1%, fully meeting the enterprise's accuracy requirements. The specific results are as follows:

• Coal Pile 1: Measured volume 177.335 m³, converted weight 141.868 t, weight error 1.6%
• Coal Pile 2: Measured volume 872.298 m³, converted weight 697.838 t, weight error 1.5%
• Coal Pile 3: Measured volume 624.973 m³, converted weight 987.470 t, weight error 1.8%

Application Advantages

• Higher Measurement Accuracy: The SLDL6300 uses 3D laser scanning technology to obtain centimeter-level point cloud data, reducing human errors and making the measurement results more reliable than traditional methods.
• Greatly Improved Efficiency: A single person can complete the measurement of a large coal pile in tens of minutes, which is 10-20 times more efficient than manual measurement, significantly reducing labor costs.
• Digital Closed-Loop Management: The measurement data realizes the digitalization and visualization of coal pile management, providing data support for enterprise production planning and inventory optimization.
• Strong Environmental Adaptability: The SLDL6300 supports multiple operation modes and can work stably in complex environments such as high dust and uneven terrain.

Conclusion

SOLIDAT's SLDL6300 Laserscan Laser Coal Inventory Instrument has successfully helped overseas clients solve the pain points of inaccurate coal pile measurement and insufficient transportation monitoring. The high-precision measurement not only improves the efficiency and accuracy of coal pile management but also enhances the safety and stability of the transportation link, creating significant economic benefits for the enterprise. In the future, SOLIDAT will continue to innovate technology and provide more efficient and reliable solutions for global clients in bulk material management.
