A System Dynamics Model for Ecological Environmental Management in Coal Mining Areas in China

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.

Analysis on Environmental and Economic Benefit of Activities in Coal Mined Area: A Case Study of Tanjung Enim Mining Site, South Sumatera

“…After the coal exploration, the mined land was just abandoned; backfilled, or not backfilled; replanted, or as it is. Backfilling process refers to dumping overburden and topsoil into a basin of the mined area, then contouring the mined surface area with the assistance of heavy machinery (Daryanto et al, 2018;Hendryx et al, 2020;Shi et al, 2020;Xiao et al, 2021). Because of the acidic mined soil characteristic, the mined land is hardly restored to its original state.…”

The Balance of Outlays and Effects of Restructuring Hard Coal Mining Companies in Terms of Energy Policy of Poland PEP 2040

“…The directions of development also included new elements concerning the identification and measurement of the costs of the negative impact of mining on the environment and human health [97,98]. Moreover, there were strongly emphasized problems of reclamation [99], recognized in other countries, as well as changes in the technology of mines' functioning in the direction of energy transformation [100].…”

“…It can be assumed that coal mining companies were well prepared to adopt market-oriented policies and that they were consolidated, their debts were reduced, their financial results were satisfactory, and they were ready to develop strategic action plans under government programmes for the industry [134] (pp. [92][93][94][95][96][97][98][99][100][101][102][103][104][105][106][107]. However, the degradation process of the industry, which started in 2012, brought about disastrous effects in 2014-2016.…”
