Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] refer to figure 1 , providing a coal mine gas prediction method based on deep learning, including steps:

[0037] Integrate the original ventilation safety information, extract historical gas characteristic data from the database of mine data characteristics, preprocess the historical gas characteristic data, and establish an observable data set of historical gas characteristic data for big data analysis;

[0038] The historical gas eigenvalue data in the observable data set is divided into two parts, which are used as the training set and the test set respectively. The trained deep neural network model DNN is trained through the training set, and the trained deep neural network model is trained through the test set. DNN for testing;

[0039] Input the real-time gas characteristic data into the trained deep neural network model DNN, and obtain the ou...

Abstract

The invention discloses a coal mine gas prediction method based on deep learning. An observable data set oriented to big data analysis is established according to actual production data collected on site; data preparation of high-dimensional gas data is carried out; the method comprises the steps of preprocessing measurement misalignment and missing data, preprocessing a time sequence, normalizingsample data, reducing dimensions and the like. The method comprises the following steps of: selecting a deep neural network-DNN (Deep Neural Network) as a gas data sensing model; based on Keras, a distributed deep learning framework is established, a plurality of machine learning algorithms are integrated, then an automatic machine learning engine is created, a model is trained, testing is completed, and intelligent prediction of coal mine gas is achieved by applying the deep neural network regression model. By means of the method, a more accurate risk pre-judgment basis can be provided for the mining and tunneling process of the coal mine.

Description

technical field [0001] The invention relates to the technical field of coal mine ventilation safety information, in particular to a coal mine gas prediction method based on deep learning. Background technique [0002] Coal mine gas prediction is a prerequisite for the realization of gas accident prevention, and the accuracy of coal mine gas prediction directly affects the practical application of prediction results. Traditional gas prediction methods are restricted by data samples, information processing technology, and the scale of prediction models, so their practicability and accuracy cannot meet the actual needs of the site. With the continuous development of coal mine safety production mechanization, automation and informatization, information related to coal mine underground ventilation safety has gradually accumulated, forming a massive collection of high-dimensional information. However, due to historical and technical reasons, these huge amounts of data are left id...
