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,...
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...
There are many uncertainties which have the characteristics of high investment and high risk in coal-bed methane underbalanced drilling. If the potential risk and its state can be predicted in advance, the probability of risk occurrence will be reduced to the minimum extend. On the basis of risk identification of coal-bed methane underbalanced drilling, it concludes that the drilling risks mainly...
Presently, China's coal mine safety situation is grim, in which a very important reason is lack of safety investment dynamic. Safety investment dynamic analysis and assessment can provide decision basis for effective control and guide. The paper analyzed impact indicators of coal mine safety investment dynamic; established unascertained clustering based coal mine safety investment dynamic assessment...
Presently, coal mine safety situation in China is still severe. One of the most important reasons is safety investment insufficient. Safety investment prediction can provide decision basis for efficient controlling and guiding safety investment. The paper analyzed coal mine safety investment influence factors and established coal mine safety investment prediction model based on support vector machine...
