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,...
Safety warning management is a new method of safety management in coal mine, which helps to ease the prevention shortage and change passive situation facing safety accident. The object on early warning management is greatly important for warning management, which affecting warning results seriously. This paper has constructed safety warning management factors system based on literature summary, expert...
As for coal enterprise, whether it should maximize profit, or maximize sales for the target that more beneficial to development of coal enterprise and coal industry, which is always a study problem in economy circles. Economics theory is applied in this thesis, infer that coal enterprise' target profit of seeking sales maximization is lower than maximal possibility profit, and more Safety -Energy...
In recent years, along with the aggravating social competition, the coal enterprises take security cost control more seriously, but when those coal enterprises carried on the management, they often neglect many recessive security cost. However, only by recognizing and taking these recessive security cost under control, can we improve the cost conditions of coal enterprise fundamentally, promote its...
Through analysis on domestic flat pitch seam Cross-cut exposing prominent anti-Outburst Coal technology, in connection with Cross-cut coal and Gas outburst law, take flowing deformation assumption as theology mechanism principle, study up on the effect of coal seam crosscut obligate rock pillar's resistance to the prominent, the way of Gas drainage, the form of coal seam Cross-cut pilot tunnels' and...
This paper adopt fuzzy comprehensive evaluation method to evaluate the mining methods for complex difficult steep coal seam. Using FAHP to calculate weight vectors of each assessment factors, in order to get more real reaction of sorting relationship between various factors. Then calculate evaluation scores for various mining methods by establishing the mining methods fuzzy comprehensive appraisal...
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...
Based on unexpected factors during the coal production, supply, demand, transport, preservation, and safety, a coal supply chain is centered on coal producers and cooperated with, suppliers, salespersons and users. And it adds to the risk and safety department which is responsible for the safety and management of the overall supply chain. Meanwhile, by using the method of subsection risks diagnosis,...
Minerals are the primary resources of economic and social development. But the nature of mining and mineral development is such that various adverse impacts upon the local communities are usually inevitable. Consequently, the process of mining-led economic and social development is often associated with tensions among corporate mining objectives, recipient community needs, and governmental policy...
The sense of mining progress was analyzed. The model of production function considering mining technical progress and mining condition of coal bed was proposed. The growth equation and the production function were deduced when the two factors were considered. The research indicates that mining technical progress has a great effect on the output of mine enterprise when mining technology develops promptly...
Coal mines safety condition decides the economic condition of the regional development on one hand, more importantly the safety of employees working for mines on the other. This article has introduced a scientific system to evaluate the safety level of coal mine based on AHP so as to give out significant information for the managers of coal mine to make and implement corresponding polices concerning...
The safety investment and benefit of coal has two characteristics: fuzziness and gray character. Considering the limited consideration of safety investment of coal, a mathematic method based on fuzzy-gray relational degree is proposed, a synthesized relational degree is formed by connecting the gray relational degree and Oushi distance of fuzzy sets. Based on the contents as concept of coal mining...
Based on the background of multi-rope friction hoisting transport system and the factual loading of hoisting skip as the object monitored, a practical and economic monitoring system scheme has been put forward, which is not only capable of monitoring the factual loading of hoisting skip but also can detect the quantity of unloaded coal left in hoisting skip after the process of unloading expediently,...
Aim at the unsafe manager behavior underground the China coalmine accidents taking place frequently recently, the two-layer principal-agent relationship in China coalmine management is analyzed, the double level multi-task incentive model consisting of government, company and coalmine manager is constructed, the coalmine manager's work behavior under optimal incentive contracts is analyzed and some...
The coal safety regulations play an important role during Chinese coal production, which greatly effects the progress of Chinese mining technology. Furthermore, in the market-oriented condition, safety input is an important factor that increases the production cost of the mine companies. By constructing profit-maximizing model, the article discusses how do the safety regulations impact Chinese coal...
Through setting up models, the coal enterprises' threshold of safety input is obtained with the real option approach. Further, the results shows: the coal enterprises' safety input are influenced by following aspects critically: the efficiency of safety technologies, the quantity of the input, the raise speed and the uncertainty of the safety technical efficiency, and the policy and monitor of government.
Safety is one of the key problems people concern about most not only at present but also in the future. Currently there are many hidden troubles threatening safety. Particularly, the safety problems in coal mines are very serious and in great need of management and control, because they not only influence humanpsilas increasing demand for energy, but also affect severely environment. Hence, itpsilas...
