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.
Using the methods of fault types and the effect analysis identified all types of risk existing in mine ventilation system and its index system. Deciding the constant right value for each index through the method of combing the fuzzy interval method and the analytic hierarchy process method and achieving variable weight using the value change of hazards and in the end establish the mathematical model...
To implement the sustainable development in iron and steel industry, many iron and steel enterprises have begun to explore the way of green manufacturing. In this paper, a relative green degree evaluation model for equipments of iron and steel enterprises is established. A five-dimension evaluation index system for equipment is created which is TPCRE (T-Time, P-Performance, C-Cost, R-Resource, E-Environment)...
The situation of the safety production of enterprise is very severe in China due to the insufficient safety investment. The accounting has unique effect if using it to manage the safety investment activity. However, the accounting function in safety investment of enterprise in China does not effectively mobilized. Based on the factors, Current situation of accounting of safety investment of enterprise...
In the article, the mode of controlling and pre-warning risks in safety conditions of coal mine productions and the corresponding MIS are designed according to the safety practice of coal mines productions and the actual state of domestic and abroad researches and by use of modern safety management theories and methods and coal mine essential safety management system. Then the effects of applying...
With the increasing complexity in civil engineering projects, the multi-program group has become a large-scale system problem. Three analysis models for safety evaluation are discussed in this paper: safety comprehensive analysis model, safety performance analysis model and safety contribution-rate model. Then the safety indexes of these models are deduced and build up respectively. Furthermore, the...
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...
Due to the serious condition of safety production in hydropower construction project on the whole, it is an urgent need to evaluate hydropower engineering construction safety. But the problem of the mapping relationship between evaluation index and accidents, fixed and variable weight, randomness and fuzziness and so on, can't be solved through the traditional safety evaluation method for hydraulic...
On the basis of present domestic and international safety production indicator systems, combined with practical work of work safety supervision in Beijing, we put forward constructive principle, framing and primary substance of work safety statistical indicator system, define more than 200 statistical indicators in 9 contents. Establish information system of Beijing work safety indicator system and...
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...
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...
