Background
The coal mine water damage refers to the flood condition caused by the infiltration and accumulation of underground water in the coal mining process, and the water damage can cause serious consequences such as equipment damage, casualties of workers, production interruption and the like in a mine; the traditional water damage prediction has some limitations and disadvantages in terms of nonlinear relation processing, subjectivity, data processing, real-time performance, multi-factor interaction and the like, and the problems limit the accuracy and reliability in terms of coal mine water damage prediction, and the main problems are as follows:
firstly, the nonlinear relation is difficult to process: conventional water damage prediction systems are generally based on statistical methods or empirical rules, and it is difficult to accurately model complex nonlinear relationships, which results in limited prediction capabilities of conventional models in the face of actual complex coal mine environments and water damage factors;
secondly, depending on human factors and experience rules: some traditional models rely on expert knowledge and empirical rules for modeling and prediction, and such subjectivity and artificial interference may lead to deviation and inaccuracy of the model, and also increase subjectivity and irreproducibility of the model;
thirdly, data processing and feature selection are difficult: the traditional model has certain difficulty in data processing and feature selection, and the traditional method can not effectively process a large amount of complex data or can not extract key feature information from the complex data, so that the performance of the model is reduced;
fourth, lack of real-time and dynamic properties: traditional models tend to model and predict based on historical data and static assumptions. However, coal mine environments and water damage factors may change with time, real-time monitoring and dynamic prediction are required, and the conventional model cannot meet the requirements of real-time performance and dynamic performance;
fifth, multi-factor interaction and complex systems cannot be handled: the coal mine water damage involves complex interactions between multiple factors, which are often difficult for conventional models to fully account for, and simplified assumptions and model structures of conventional methods may not accurately capture the complex behavior of the multi-factor interactions and systems.
