Study On The Synergy Of Coal Mine Production System And Key Subsystem Improvement

According to the central government work report and the economic situation , we can see that China’s economic development is into a new normal,and the coal industry as the traditional industry is also facing transformation .The State Council issued "Opinions on the Coal Industry to Solve the Excess Capacity" on February 1, 2016.The article put forward clear goal and three - dimensional solution to supply - side reform.Coal mine production system is a giant complex system, so it is very important to study the optimization and upgrading of coal mine production system from the perspective of synergetics in system science.This topic assesses the synergy of coal mine production system from the perspective of synergetics and finds the order parameters of coal production system to improve the coal mine production system.In this paper,we first analyze the background and significance of the evaluation of synergistic performance of coal mine production system and the improvement of its key subsystem, and summary the research status of related topics at home and abroad. Based on this, the research methods and technical routes of this paper are discussed and the relevant concepts are briefly described.At the same time,the concepts of coal mine production system, coal mine production system synergy, sequence parameter and system reliability is defined, and the coal mine production system is divided based on the structure function and constituent elements respectively. The two-dimensional evaluation index system of coal mine production system coordination degree is established.And the evaluation model of coal mine production system synergy is established based on the entropy and the Topsis method, the improvement model of key subsystem established based on system reliability and system dynamics. Based on the data of capacity, safety, organization and management, information and so on to Zibo Mining Group Xinhe mining production system., according to the synergistic evaluation model, the ability of the main vertical shaft lifting system is determined as the order parameter. This topic studies the reliability of the key bottleneck subsystem - shaft lifting system by using the system dynamics method,and the non -synergistic factors from the three aspects of human -machine - environment. In view of these reasons, the author puts forward some suggestions for improving the main shaft lifting subsystem.
