Abstract

In recent years, mounting attention has been paid to ecological environmental management in coal mining areas in China. This paper conducts a system dynamics (SD) model for ecological environmental management in coal mining areas. Firstly, the whole causal loop diagram of the system is built to illustrate the general system. Secondly, five subsystems are presented according to the causal loop diagram. Then, given the stable investment for ecological environmental management in coal mining areas, our objective is to find a better allocation that can get the best ecological environmental quality in coal mining areas. Notably, we present six allocations of the investment for ecological environmental management in coal mining areas. The results show that, in allocation 4, we can get the best ecological environmental quality in coal mining areas. That is, the best improvement of mining environment can be achieved by distributing the treatment cost highly on the proportion of investment in green vegetation.

Highlights

In the past few decades, due to the fast economy development and the soaring demand for coal to generate electricity, China has become the largest coal producer and consumer in the world [1]
If we put a higher proportion of investment in air pollution, we can get a better effect in dealing with the problem of air pollution
If we put a higher proportion of investment in solid waste pollution, we can get a better effect in dealing with the problem of solid waste pollution

Summary

Introduction

In the past few decades, due to the fast economy development and the soaring demand for coal to generate electricity, China has become the largest coal producer and consumer in the world [1]. While coal makes an important contribution to energy generation, its environmental impact has been a challenge [2]. The expansion of the coal mining industry in China has placed high pressure on the ecological environmental management in coal mining areas. Such as air pollution, water pollution, solid waste pollution, vegetation destruction, land damage and so on. How to effectively improve the quality of the ecological environment in coal mining areas has become an urgent problem to be solved
