Problems solved by technology

[0004] However, the predecessors paid less direct attention to the operation situation in front of the working face. The underground operation and construction situation mainly comes from the work scheduling plan or artificial statistical records. There are inevitably errors and omissions, and the timeliness has been greatly affected. limit

Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] Embodiments of the present invention are as follows:

[0044] The gas concentration data of a coal mine mining face is collected by the gas concentration sensor as the research object of the embodiment. At the same time, the operation type tracking and recording in the cycle period is manually carried out as a sample library. The specific implementation process is as follows figure 1 As shown, the specific method is as follows.

[0045] Step 1. Automatically and continuously obtain the dynamic time series data of gas gushing from the tunneling face through the mine safety monitoring system. In this embodiment, the mine uses the gas data obtained by the KJ90 (substa...

Abstract

The invention discloses an intelligent identification method of an underground working face operation type based on gas concentration parameter. The method comprises the steps of firstly obtaining thegas concentration data of a working face from a mine safety monitoring system, and storing in a gas parameter database, processing the gas concentration data in the database by adaptive noise reduction filter, and then establishing the historical gas concentration data sample set on the basis of the classification of operation types and the extraction of sensitive characteristic parameters, and constructing the adaptive modular rough neural network prediction model, and identifying the corresponding operation types by using the constructed prediction model. The method of the invention has obvious noise reduction effect, can effectively remove noise while retaining the effective information in the gas concentration time series, can realize analysis and identification of the working type ofthe working face, and can better realize the depth mining and the secondary utilization of the gas concentration data.

Description

technical field [0001] The invention relates to the field of mine gas disaster monitoring and prevention, in particular to an intelligent analysis and identification method for operation types of mine excavation working faces based on characteristics of gas concentration data. Background technique [0002] China is the world's largest coal country. According to my country's "Energy Medium and Long-term Development Plan (2004-2020)", it is clearly pointed out that my country will continue to use coal as the main energy source for a period of time in the future. At present, my country's coal mining industry has entered a period of deep mining, and the mining depth is increasing year by year. During the period of deep mining, mine gas pressure increases, ground temperature increases, ground stress increases, and mine disasters become more and more serious. Coal mine accidents and disasters have seriously hindered the situation of coal safety production in my country and hinder...
