Safety input is a way of safeguarding mining, as well as one of main reasons for the increased growth rates of Total Factor Productivity (TFP). To figure out the contribution of the safety input to mining economic growth, a new production safety index system with six principal items describing China mining safety was constructed. The study found that China mining production safety level was improved...
Modern mine production has brought unprecedented demands on the safety, high yield, and high efficiency, which means to realize the integration management control of decision making, production process management, and process control on the basis of the production mode on spot adopts automation equipment. The aim of establishing integrated management control information system of mine production 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 theory of system engineering, coal mine production safety has been analyzed. From workers, production process, coal production and economy, coal mine production safety evaluation indexes have been confirmed, and then the BP neural network model of coal mine production safety evaluation has been built. After training and testing the model, the model can accurately evaluate the coal mine...
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...
