Abstract:
In order to accelerate the construction of coal mining enterprises emergency management mechanism and enhance emergency capability of coal mining enterprises,a method for evaluating coal mining enterprises emergency capability was worked out according to the characteristic of HD. A network structure of evaluation indicators was constructed on the basis of correlation degrees between indicators. An evaluation model was built according to the network structure. Evaluation steps were given. The model was applied to evaluate the capability of a certain coal mining enterprise in Huainan city,China. The results show that the evaluation method can give weight on the basis of behavioral mechanisms,and the actual rescue capability is the most important for this coal mining enterprise and its weight is 0. 170 7,the emergency response capability is the lowest and its weight is 0. 075 0,all basically consistent with the actual situation of this coal mining enterprise.Cite
In order to reduce the cost, improve the productivity and make full use of resources of enterprise, the choice of enterprise logistics mode appears particularly important. On the base of domestic and foreign research achievements, set pair analysis is introduced in this article into the choice of coal enterprises logistic pattern, namely self-management, Joint venture, and outsourcing, it constructs a comprehensive index system in order to make much better choices for coal enterprises.

The work is devoted to the problem of cost-effective adaptation of coal mines to the volatile and uncertain market conditions. Conceptually it can be achieved through alignment of the dynamic characteristics of the coal mining system and power spectrum of market demand for coal product. In practical terms, this ensures the viability and competitiveness of coal mines. Transformation of dynamic characteristics is to be done by changing the structure of production system as well as corporate, logistics and management processes. The proposed methods and algorithms of control are aimed at the development of the theoretical foundations of adaptive optimization as basic methodology for coal mine enterprise management in conditions of high variability and uncertainty of economic and natural environment. Implementation of the proposed methodology requires a revision of the basic principles of open coal mining enterprises design.

A theory and method about the evaluation performance of an enterprise based on orientation of development have been firstly put forward to meet the need of market economy in this paper. The necessity of the theory and method has been analyzed from the angle of the development of the theory on enterprise evaluation and the need of the practice, and then, the enterprise of coal mining is taken as an example, the index system on the evaluation performance has been set up from quantity, competitiveness, effectiveness and riskiness of its development. As coal mining enterprise development depends on their natural condition, and the different advantage on “resource” and “position” results in the differential in their input and output, so the present of evaluation standard which must be on the basis of the enterprises have been classified. The evaluation standards of each index have been determined using different method according to the principle of science, encouragement, dynamicalness, estimability and their characteristics. Finally, a synthesis evaluation model on development performance has been built.

Firstly,this paper defined the concept of the coal resources saving degree from three dimensions such as resource,economy and environment,and pointed out the coal resources saving degree would consist of different rates contributed to coal resources saving made by such three independent sub-systems as the mining,washing and processing,comprehensive utilization.Secondly,this paper constructed the fuzzy evaluation model of coal resource saving degree,including the model framework,index system and evaluation method.Finally,this paper calculated and horizontally evaluated the coal saving degree of Jibei mine in 2006 by means of the fuzzy evaluation model.The comparisons of analyzed results with the practical data of mines verified the scientific nature of the model and the accuracy of evaluated results,and some suggestions for the main problems existed in coal resources saving of mines are pointed out.

For the sake of solving the problem of inadequate safety investment and irrational investment structure in coal enterprises,AHP and GRAP were used to define the correlation degree value between safety investment and output in coal enterprises. On this basis,a nonlinear programming model based on goal of minimum total amount of safety investment in coal enterprises was built with the method of goal programming. The results show that there is no strict positive correlation between safety investment size and safety output in coal enterprises,that reasonable structure of safety investment is an important safeguard against safety accidents,and that attaching great importance to industrial hygiene and education investment helps to ensure work safety in coal mines.

In order to roundly and scientifically evaluate overall benefit in coal enterprises, an evaluation index system of overall benefit in coal enterprises was established based on the definite selection principle of evaluation indexes and the characteristics of coal enterprises, and the evaluation of overall benefit in coal enterprises was studied by means of the entropy coefficient method. The analysis of applied results of an coal enterprise shows that the evaluation index system of overall benefit in coal enterprises is reasonable and the model of multifactor comprehensive evaluation based on entropy is suitable to evaluate overall benefit in coal enterprises.
