For the coal resources working which are affected by the coal mine flooding seriously, this paper make an analysis on the factors which affect the coal mine flooding emergency ability evaluation model based on GA-WNN is established through the wavelet neural network value which is optimized with genetic algorithm. This model combined the global optimization ability of genetic algorithm with the time-frequency localization of wavelet neural network. This combination can make up for many defects (for example, the neural network structure should be given artificially, the function can got local minimum easily and so on). Therefore, the local mine flooding emergency ability evaluation model based on genetic algorithm and wavelet neural network have higher reliability and calculation ability, and is beneficial to the pre-control management for coal mine flooding rescue.

In the new era, college teachers should improve their teaching ability, espe-cially in terms of adaptability. However, most college teachers lack sufficient adaptive teaching ability, failing to create an adaptive teaching environment. To solve the problem, this paper explores deep into the extension strategies for improving the adaptive teaching ability of college teachers. First, the problems of college teachers in adaptive teaching were identified, and the key aspects of adaptive teaching ability were enumerated theoretically. On this basis, several extension strategies were put forward to improve the adap-tive teaching ability of college teachers. To evaluate the improving effect, the authors developed an evaluation model for the adaptive teaching ability of college teachers based on the extension theory. Overall, this paper fully ex-plores the improvement of adaptive teaching ability of college teachers via theoretical analysis and modelling. The research results boast good applica-tion prospects.
