Safety management of coal mine is an important part of enterprise management, it is also the important guarantee to achieve work safety. The ERP system of coal mine safety is an advanced, dynamic safety management mode, it can improve the safety management level to implement ERP system, prevent and reduce accidents, too. The paper describes the management ideas and models of ERP system, and applies...
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.
In this paper, we propose a new multi-expert decision-making method based on induced OWA operators for coal mine safety evaluation. Aggregation operators are crucial to decision-makers when they make decisions. The Ordered Weighted Aggregation (OWA) is the most common operator to aggregate the arguments that are the exact numerical values. However, the decision-makers may have vague knowledge about...
Human, machines and environment, three main factors contained in transport system in coal mines, and their impact on transport accident have been analyzed with system engineering theory of man-machine-environment in this article. Reasons and control of human mistakes, relationship between human and transport accident, analysis of machines' stability and fuzzy comprehensive evaluation have been deeply...
RFID is a non-contact automatic identification technology that uses radio frequency signals automatic recognizes target and access to relevant data. The identification work does not require human interference and can work in variety of harsh environments. But if there is no network to transmit data, it will be difficult to play its advantage. Under the influence of environmental conditions, the traditional...
The Coal mine safety is the keystone of the industry safety in our country, in which area, ventilation system is the basis to control the hazards such as gas explosion. Ventilator system is an important part of ventilation system, which can be seen as cold standby system, also is markov repairable system. Here we discussed and calculated the reliability and remain life probability of ventilator system...
This article describes the design of a wireless sensor network based on ZigBee technology. It is mainly used for collecting and transferring the various monitoring information about the coal mine underground. Then the data will be analysed and processed in the monitoring system outside, so that we can ensure the safety of the coal production and effectiveness better.
Based on the analyses of the Supervison Workstations of coal mine safety, the shortcomings in traditional methods for fault diagnosis and the promising usage of expert system for the fault diagnosis is constructed. The aim for building the expert system is to make the testing and maintaining equipment for the supervison working better. This paper introduces a kind of expert system based on function...
The relation among job satisfaction, stress level and self-efficacy of safety staff in coalmine was investigated by a questionnaire survey conducted to 43 employees in a state-owned coalmine. The results showed as follows: stress level could predict job satisfaction negatively; self-efficacy could not only predict job satisfaction positively, but also adjust the effect of stress level on job satisfaction;...
The construction of intelligent mobile phone coal mine production and safety-monitoring system is based on the various existing safety-monitoring systems, for instance the coal mine gas-monitoring system etc, and coal mine production management system already in use in the coal mine. It makes use of intelligent phone as a platform and realizes its functions of safety monitor and production control...
Safety is one of the key problems people concern about most not only at present but also in the future. Currently there are many hidden troubles threatening safety. Particularly, the safety problems in coal mines are very serious and in great need of management and control, because they not only influence humanpsilas increasing demand for energy, but also affect severely environment. Hence, itpsilas...
A numeric simulation of gas migration in a fully mechanized coal caving stope based on Lattice Boltzmann Method is put forward. A mining stope includes an inlet air tunnel, a return air tunnel, a working face and a goaf. There are two different states of air movement in a stope: turbulent flow in the inlet air tunnel, the return air tunnel, the working face (the three parts are simplified as working...
This paper discussed the application of virtual reality technology and its application on prevention of coal and gas outburst in coal mine. With the help of virtual reality technology, the vivid and process of coal and gas outburst in coal mine could be obtained. The application of virtual reality technology on prevention of coal and gas outburst included development such as system requirements, data...
Reinforcement learning is an algorithm without model which is learning what to do--how to map situations to actions-so as to maximize a numerical reward signal. Reinforcement learning provides an available method to the systems, which are very difficult to build up accurate models around complex environment. But now many practical problems demand a maximum reward with not much cost (expense). For...
Based on the ideology of "using the monitor data to reflect the production safety and using the risk analysis and safety evaluation methods to guide safety management to realize the objection of mine coal safety state warning and assistant decision-making support system", with Bofang coal mine of Shanxi Orchids Corporation's practical experience in safety state management, we set up a warning...
The paper studied on gas prediction problem. According to traditional prediction methods on coal mine safety being offline without dynamic prediction function and the shortcomings in the traditional online learning with least squares support vector machine (LS-SVM), this paper gave an improved online prediction algorithm of LS-SVM. This algorithm was used in gas prediction of some coal mine. By comparing...
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...
