Description

Method, device and system for predicting gas content based on multi-layer perceptron model Technical Field The invention relates to the field of coal mines, in particular to a method, a device and a system for predicting gas content based on a multi-layer perceptron model. Background Gas disasters have historically been a core challenge in restricting coal mine safety production, and its prediction method has been a hotspot in research in the field. Traditional gas prediction relies mainly on the field experience of engineering technicians, combined with static mathematical models to make inferences. Although this approach plays an important role at the time, there are significant limitations on the accuracy and precision of the prediction. In recent years, with the breakthrough of the Internet of things and sensor technology, advanced means such as distributed optical fiber monitoring and laser spectrum detection are applied, so that dynamic real-time acquisition of key parameters such as gas concentration, pressure and flow is realized, and the accuracy of monitoring data is remarkably improved. However, gas prediction still faces two major core problems, namely that firstly, the unique adsorption gas storage mechanism of gas interacts with diversified coal mining processes to increase the complexity of the construction of a prediction model, and secondly, the prior art system is difficult to synchronously realize early warning of disasters and effective prediction of the whole working face range. The method is based on the fact that the gas content is closely related to various geological and engineering factors such as coal seam thickness, burial depth, gas emission quantity and the like, and the factors are directly and indirectly related to each other in a complicated and changeable manner, so that the method is a deep cause of difficulty and complexity in gas prediction work. It is worth noting that this situation is coming as machine learning technology is becoming more mature. Machine learning is particularly good at dealing with complex regression prediction problems under multi-feature, multi-constraint conditions. In view of the fact that gas prediction itself is a typical scenario highly correlated with multi-source information and multiple conditions, it is possible to implement fast and accurate gas prediction by using machine learning technology, and represents an important development direction in the future of the field.
