This article starts from the current background of coal mine safety situation and combines with the status of coal mine safety research and computer network technology development, it gives the design of physical structure and logical structure of multimedia alarm system for coal mine safety and discusses and researches its implemental key technologies.
Based on the System Dynamics theory and the causality of the factors influencing competency of mine special operators, this paper established a dynamic simulation model of Training function on the Influencing Factors of mine special operators' Competency. The studies showed, under the same training inputs, coping capacity, sense of security responsibility, and self-management skills have more visible...
A novel extension evaluation method of coal mines geological safety was proposed in this paper. Based on the extension theory, a matter-element model was established for qualitatively and quantitatively describing the safety evaluation problem of coal mines geological safety. The degree of relation based on the dependent function was employed to determine the nature and the level of the safety in...
Structural equation model is constructed to discuss the interaction between affecting factors of safety management capability of coal mine. Fundamental data is acquired from questionnaire of coal mine worker. 20 factors in all classified into four layers: worker, team, firm and environment are extracted in questionnaire. Taking factors of worker layer as endogenous latent variable, taking factors...
The gas supervision is a safety core of the coal mine production, which widespread existent a trouble, gas emergence big data, namely the pulse interference, the cause of the gas signal mistake alarm, is hardly resolved very often. In this paper, the reason and characteristics of gas emergence big data are analyzed to establish a kind of filter based on BP Neural Network. Through great quantities...
