Sukcesy współczesnego górnictwa możliwe są dzięki doświadczeniu pokoleń górników, którzy poprzez analizę swoich błędów, zarówno w organizacji robót poszukiwawczych jak i wydobywczych, a później przeróbczych uczyli się bezpiecznej i efektywnej produkcji. Zejście poniżej poziomu terenu wiązało się z nieznanymi dotąd zagrożeniami i nie było innej metody niż nauka poprzez doświadczenie, a to wiązało się...
In order to reduce the costs and maximize the profit, many coal mining enterprises are gaming in the safety investment under the coal-mining supervision in China although relative supervision provisions are strict, which results in mine accidents happening. In order to make sense the causes that are behind the economic motivation, based on the gaming model with two variables, technology and cost,...
This paper aims at applying ART-2 neural network algorithm on the research of coal mine safety risk assessment and finally obtains good empirical results by taking some coal mines as the study sample. The results show that the ART-2 neural network algorithm is an appropriate method to assess the safety risk of coal mine. The analysis of empirical results is consistent with the actual situation.
Coal mine safety funds are divided into employee's safety input funds, safety technology funds, and safety management funds. It is great significance for the realization of the optimal safety input orientation and the selection of safety projects to scientifically allot each safety funds. This paper uses co integration test and Granger causality test to explore the long-term steady relationship between...
As we all know, coal is an important basic resource which accounts for about 70% in the primary energy structure. Coal mining enterprises have the primary responsibility of the mine accident. Therefore, it is a great significance with researching the production strategy of coal mining enterprises. In this paper, we use the game theory to analyze the interest between safe-production of the coal mining...
The purpose of this paper is to solve the difficult problem that coal mine accident cannot be effectively contained by the government's severe consolidation, and to deal with the main stakeholders' conflict of interest and information asymmetry in coal mine safety regulation. Systematically, we analyzed the three-tier principal-agent relationships which formed in the coal mine safety supervision and...
The occurrence of accident is influenced by multiple factors, so in the process of accident warning model construction, we should take full account of the relationships between all of the factors and the accident and the roles that these factors played in the accident. This paper constructs an accident warning model by employing the entropy weight and extension theory. On one hand, this model employs...
This paper use the gray single-level evaluation evaluate coal enterprises' security condition with a gray theory, let the coal enterprise's evaluation be more scientific and more realistic and provide a reference for the safe appraisal of coal enterprise.
With the deep development of coal mining, the underground mining will face serious threats to the confined aquifer, mining under safe water pressure of aquifer has become the main way to mine deep coal resources. At the same time, the auxiliary waterproof method is particularly important to adapt to the mining. Faced with the mining technological challenges in the deep coal mining, with the analysis...
This paper investigates the security role of “three laws and one regulation” on coal mine safety production in China through a dummy variable model analysis. The results show that the security role of “three laws and one regulation” made the death rate reduced by 0.895 persons per million tons coal. The terms of economic penalties and sanctions would be closely consistent with the level of economic...
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...
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...
A dead-circle of coal-mine disaster has formed in the long-term games among local government, coal miners and coal-mine managers under the special ecological circumstances of Chinese coal-mine. The mechanism of it is discussed by game theory based on enterprise ecology in this study. It concludes that the collusion between the local government and coal-mine manager will be more rampant along with...
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...
Aiming at the drawbacks in disposing coalmine accident hidden troubles the paper sets forth the market-oriented concept and method of coalmine accident hidden troubles. The method fixes on the quantitative value of unsafety state and the hidden troubles factors composed with behavior, technology, environment, and equipment, and establishes accident hidden troubles price system. It constructs the market-oriented...
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...
It is very important that to establish a rational and quantitative mathematical model for the safety management of coal enterprises. The model can help managers to develop practical safety management objectives. It can help people find out the safety production trends also. In this paper, time discrete state equation on the principle of Cybernetics was used to study coal mine safety production model...
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...
