Present Situation and Development Trend of Gas Emission Prediction Technology in Coal Face

The accurate prediction of gas emission in coal mine is of great significance to the arrangement of drilling holes and the prevention of gas in coal mine gas drainage. In this paper, eight kinds of prediction methods for gas emission are described in detail, and the prediction process is discussed and analyzed in detail. This paper points out the problems existing in the prediction of gas emission in coal mine. In view of the existing problems, it puts forward to strengthen the study of gas geological law in the future, and comprehensively analyzes the law of gas generation, migration and occurrence in combination with multi-factors. It is of great significance for accurately predicting the amount of gas emission in coal mines. According to the main influencing factors of gas emission in coal mine, a variety of mathematical and biological genetic theories are adopted to provide theoretical support for the prediction of gas emission.
