Abstract

The present invention provides a prediction method of a gas emission rate. The method comprises the steps of: 1. arranging a gas sensor, performing real-time monitoring of gas concentrations, and transmitting data to a database to calculate and store a gas emission rate; 2. extracting safety gas emission rates in the database, constructing a gas emission rate prediction model, performing gas emission rate prediction of input parameters according to the gas emission rate prediction model, and outputting a predicted value; 3. comparing the predicted value with a real-time monitoring value, forming error analysis, and updating the gas emission rate prediction model; and 4. repeatedly performing the steps 1-3, and performing real-time monitoring of the gas emission rate. Through adoption of high non-linear mapping of a neural network model and an Matlab language computing environment, data in the data is extracted in real time to correct the gas emission rate data model, and therefore, predicted errors are small, the prediction is more scientific and accurate, and scientization and quantification guidance is provided for avoiding outburst of gas.

Description

technical field [0001] The invention relates to the technical field of coal mine safety, in particular to a method for predicting gas gushing volume. Background technique [0002] At present, the safety situation in coal mines is very severe, and major accidents occur from time to time. Although various safety monitoring devices are equipped in coal mines, these devices do not have the ability to predict disasters and cannot take measures in advance to avoid major accidents. [0003] Mine gas is the main unsafe factor in the production process of coal mines. The amount of gas emission has an important impact on mine design, construction and mining. Correctly predicting the amount of gas emission and finding signs of gas emission are of great significance to mine safety production . Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a method for predicting the amount of gas emission, which can predict the amoun...
