In recent years, coal industry has got rapid d
2、evelopment in China,and does important contribution to economy growth. The problem of mine safety has always been a shackle to the sustainable development of coal enterprises. It is a significant task to study mine safety problem from a new angle of view. This paper has a systematic thought combined
3、 with the development of complexity science in recent years, and forms some revelations on the study of coal safety problems.Keywords: science of complexity; coal mine safety; chaos1 Development of Complexity ScienceThe science of complexity takes complex system or the complexity of system as its st
4、udy objects. Different scholars give different definitions to complexity. It is difficult to give an exact definition. Combined with some points of view, the complexity of system can be mainly embodied in the following aspects: 1) The connections between cells of system are wide and tight with netwo
5、rk. Therefore, the change of any cell will be affected by the changes of other cells, and will cause changes of other cells. 2) System consists of many agents with a multi-level and multi-function structure. Every level is the cell of upper level, and is helpful to the realization of a certain funct
6、ion. 3) System consists of feedback annulus. In the process of development, system can learn continuously and have a recompose of its level structure and function structure. 4) System is open to environment; it has a close relationship with environment, and has an interaction with environment. 5) Sy
7、stem is an evolvement system with self-adapting ability. 6) It cannot be explained with traditional theory and method. 7) System has the characteristics of dynamic and non-linearity. 8) System has the character of span level, such as embedded, interlinked, inter influenced and affected.Complex syste

9、racter of these systems is that behind uncertain changes, there comes out some uncertain orders. The aim of complexity study is not only to reveal and describe the locomotion principles, but also to solve the problem of forecasting and controlling of the complex system that seems unsolvable and cann

11、uate School was established. They tried to reveal the general principles dominating the complex system by gathering personnel and thoughts of these fields. Brussels College under the leadership of Prigogine and coauthored with Nilicos, wrote the famous book “Exploration of Complexity”, and set a str
12、ong foundation to this science. The study of opening complex “huge system” in our country represented by Qian Xuesen is different in approach but equally satisfactory in result with study of complexity system abroad. The concept of opening complex “huge system” abstracted by Qian Xuesen, the synthet

Outstanding scientists such as Marry Gellman, George Cowan, and Philip Anderson also put forward the th

John Holland initiates gene arithmetic, sorter system, impels the development of nerve network arithmetic, deduces the c

Fammer unites nerve network, inheritance arithmetic, classifying system model, auto-catalyze model and immunity system model together as node-associate model by the thought of connectionist. Denmark born physics Per Bak puts forward the concept of self-organization criticality.Kauff
