Mine Tunnel Measurement
As the scale of global mining resource development expands and mining depth increases, the traditional 2D plane measurement model can no longer meet the refined needs of modern mine management. Currently, most mining areas still rely on single-point measurement equipments such as total station and theodolite, which are unable to fully reflect 3D spatial information such as ore body morphology, tunnel structure, slope displacement.They also lack high-frequency monitoring capabilities for key parameters such as ore layer thickness and dynamic changes in reserves.
Industry Pain Points
Environmental Restrictions
The GPS signal will be 100% lost in the underground mine, and the optical instrument failure rate is 30% due to excessive dust concentration.
Data Discontinuity
2D drawings cannot present 3D spatial relationships such as tunnel intersections and roof deformation in empty areas
Security Risks
The accident rate of manual measurement in goaf is as high as 0.27 times per thousand people.
Efficiency Bottleneck
The daily data collection efficiency of traditional total stations is less than that required for modeling 1,000m tunnels.
Advantages
-
Zero-Touch Operation
There is no need for personnel to enter goafs or dangerous tunnels, and data collection in high-risk areas can be completed through scanning with an extension pole.
-
High Precision Survey
The technology is combined with multi-lines laser radar to achieve high-precision point cloud modeling of tunnel sections and ore body contours.
-
Accurate Volume Calculation
The empty area point cloud can automatically generate a triangulated network model, calculate the volume, and optimize the support and filling scheme.
-
Automatic Vectorization
The software can be used to slice the lane and generate the lane's DXF file in one click.
-
Freely Cutting Vertical and Horizontal Sections
For inclined ore bodies and staggered tunnels, profiles in any direction can be quickly generated to be an assistant in mining design.
