Figure 4. Flowchart of prediction model. 3. Comparison and Selection of ML Models As in previous studies [44,45,46], 13 ML regression models have been used to predict the X-PPV, Y-PPV, and Z-PPV in underground metal mines. To eliminate dimensional effects and balance the weights of inp...
Figure 4. Flowchart of the proposed algorithm. (a–f) are the schematic diagrams corresponding to each step of the proposed method. 3.1. Binary Map In this section, we convert each frame of data collected by LiDAR into a binary map. The original range data obtained by LiDAR contain invalid...
Finally, the output of the fuzzy algorithm (the left part of the pseudo-flowchart) was combined with the expert’s judgment (the right part of the pseudo-flowchart) into an integrated algorithm by converting the qualitative parameters (undisturbed and graded areas, possible final pits, power plan...
Figure 1.System flowchart for coal mine occupational safety, health management and risk control. This system manages to implement all functions needed for coal mine occupational safety, health management and risk control, with each function delivered by the corresponding module. According to the above...
