GRU-dging up Better Gas Predictions in Mines (But Needs More Testing)

This paper proposes a mine gas concentration forecasting model using a Gated Recurrent Unit (GRU) network. The model outperformed SVR, BPNN, RNN, and LSTM models in prediction accuracy and efficiency on a large dataset, but was less accurate than RNN and LSTM on smaller datasets.

Possible Conflicts of Interest

None identified

Identified Weaknesses

Limited Experimental Comparison

The experimental comparison lacks diversity. Comparing the proposed model with only a limited set of other models (SVR, BPNN, RNN, LSTM) doesn't provide a comprehensive view of its performance relative to other potential forecasting methods.

Single Dataset

The paper relies solely on a single dataset from one specific mine working face. This limits the generalizability of the findings and raises concerns about the model's robustness when applied to different mining environments or gas concentration characteristics.

Insufficient Detail on Spatial Reconstruction

While the data preprocessing steps address missing values and outliers, the paper lacks a detailed explanation of how the spatial reconstruction method is used to create the 3D input array for the GRU network. This makes it difficult to reproduce the study or fully understand the data preparation process.

Lack of Justification and Parameter Details for Preprocessing

The paper mentions using the Pauta criterion and Lagrange interpolation for data preprocessing but doesn't provide specific parameter settings or justify the choices made. The impact of these choices on the final results is unclear.

Rating Explanation

The paper presents a reasonable application of GRU networks for gas concentration forecasting and shows some performance improvements over other methods. However, several limitations, such as using a single dataset, limited experimental comparisons, and lack of detail in certain methodological steps, prevent it from achieving a higher rating.
