Safety is an element of extreme priority in mining operations, currently many traditional mining countries are investing in the implementation of wireless sensors capable of reducing the number of accidents; through early warning signs to prevent injuries, dead and significant economic losses. The application of sensors capable of measuring in real time variables of interest, promises to be of great...
The rapid development of China coal mine safety management information play an important role on improving mine safety standards, however, there exist some problems such as cannot be a comprehensive system of monitoring, evaluation and analysis of safety, forecasting of security trends, etc. Papers have researched based on this problem, carrying out research on an analysis and collection of security...
According to the statistics, roof and side fall accidents often occur and jeopardize greatly in coal mines. The variation of the strain and stress in the surrounding rocks of the mine roadway can predict the accident. How to obtain the strain and stress is the key point of the prediction. This paper provides a method on the case. Firstly the principle of monitoring stress in surrounding rocks of mine...
As a modern security design, Inherent Safety means that equipment and facilities is able to contain the inherent fundamental features to prevent accidents. Mine hoist is the most important equipment in the coal production. How to achieve safe, reliable, efficient production, has been the focus study at home and abroad. Inherent safety is reflected in hoist design, primarily through the design measures...
Accident is originated by hidden danger. Discovering and removing hidden dangers is one main approach to prevent and control accidents. This paper collected and analyzed the information of hidden dangers from multiple coal mines. On that basis, we put forward concepts of hidden danger information and standard database of hidden danger information, introduced the structure and build flow chart of standard...
The occurrence of accident be understood as mutations in a qualitative change caused by a continuous change of some of the parameters within the system. The system from security state into the state is actually a mutation phenomenon. The paper applies the Catastrophe theory and system analysis method of the accident causation, establishes the spire catastrophe model. By analysing the model, indicates...
Most of the coalmine accidents are caused by people's unsafe behavior. Based on the basic theory and research methods of behavioral science, this paper analyzed human factors and rules affecting unsafe behavior. On this basis, it proposed the wholly integrated coalmine safety culture construction methods, with strengthening safety awareness, correcting unsafe behavior and training security practices...
Prevention and control of the disastrous accident is the top priority of coal mine production safety. RBF and the combined grey neural network (CGNN) model are established. Combined with cascade-correlation (CC) and RBF-DDA algorithms, gas explosion impacting on coal mine production safety largely is analyzed. The analysis results show that gas explosion accident is caused by many reasons. The relationship...
This article establishes mine workers' safety behaviors simulation system through combined virtual reality and mining safety production. The aim is to standardize safety behavior, improve the effectiveness of safety training and accordingly reduce the accidents' occurrence in coal mine. The system is constructed by means of 3D building software. Then, an integrated development in the platform Virtools...
In order to monitor the production condition exactly and real-timely in underground and surface of coal mine, a new mobile application solutions scheme based on TD-SCDMA in coal mine is proposed. According to the high speed data service of third generation mobile communication systems, the wireless network of surface scheme was designed by the C/S structure, which can provide mobile communication...
The coal enterprise behavior safety integrated management and control system is the integrated management and control information system which takes the behavior safety as the core and aims to guide safe behavior and realize coal safety supervision. In this article, we describe the theoretical base of the system design, i.e. the theoretical frame of the accident prevention and control for coal enterprises...
Coal mine safety evaluation analyses mine's existent dangerous and harmful factors, and judges mine's potential risks. The evaluation result is propitious to guard against accidents and make management decisions. This paper analyses all kinds of influence elements on coal mine safety, constructs evaluation indexes system, measures weights using AHP, and applies dynamic fuzzy theory in mine safety...
