“…In the pressure dimension, several mining technologies, such as pool and dump leaching methods, destruct vegetations in the mining area in a large scale and form a severe impact on stability of its ecosystem [21]. Therefore, mining technology is an indicator that reflects ecological safety in rare earth mining areas, and it is represented by .…”

“…If the implementation of environmental protection policy measures in the mining area is continuously enhanced, this scenario will be transited into the scenario in type 1. The literature [21] and [25] indicates that the implementation and sustainability of environmental protection policy play a significant role in the ecological safety development in the mining area. If environmental protection policy measures are strengthened continuously, rare earth mining enterprises will continuously improve mining technology and three-waste management technology in order to prevent rectification and shutdown punishments due to disqualification after environmental assessment.…”

Rare earth mining can cause ecological problems as a result of soil erosion and water pollution in local areas. Thus assessing the development trends of ecological safety is crucial in formulating the environmental protection policies in rare earth area. Rare earth mining is a long and complicated process in which the state values of evaluation indicators for ecological safety are dynamic and continual interplay. Hence, conventionally measured indicators are inadequate in this context. An evaluation method based on the theory of quantitative scenario analysis was proposed in this study to analyze ecological safety development trends in rare earth mining areas. First, according to the PSR model framework, six indicators including "mining technology", "mining intensity", "water environment", "soil environment", "waste water, waste gas and waste residue management technologies" and "environmental protection policy", were selected to reveal the ecological safety in mining areas. Second, the crossover probability algorithm, Markov chain and nonlinear programming were utilized to construct a quantitative scenario analysis model for ecological safety development trends. Lastly, the model was verified using the data on Lingbei rare earth mining area located in Ganzhou City, China. Results showed that the quantitative scenario analysis model could be used to calculate the changes in various indicators, their cross impacts in the development process and the occurrence probability of scenario combinations for ecological safety development that were composed of the state changes of each indicator. These findings indicate that the proposed model can effectively and accurately forecast the ecological safety development trends in rare earth mining areas. The conclusions can provide a theoretical basis for environmental protection work in rare earth mining areas.

The strategy should be designed in such a way as the risk management can operate not only as a system for avoiding losses, but also risk management should allow recognizing and making use of occasions and create new opportunities for the organization. Risk management includes both an evaluation (analytical and evaluation) undertaking as well as planning and control activities aimed at minimizing (reducing) risk or maintaining it at an acceptable level. Security management can in particular be reduced to the issue of risk management, because risk is a quantitative expression of the functioning of systems in an environment where there are active sources of threats to system security. The article presents the problem of personnel allocation in hazardous conditions, emphasizing the possibilities of undertaking optimization actions in the safety management process. A mathematical model was formulated for this issue. An algorithm solving the problem of personnel allocation is presented. The proposed analysis is the starting point for determining the risk when using multi-station work.
