Coal is a vital basic energy source in China, and rail serving is its major mode of transportation. Heavy metals in street dust surrounding the coal railway do harm to the environment and pose a potential risk to human health. This paper aims to identify the effects of coal transportation hubs on heavy metals in street dust. The geoaccumulation index and ecological risk index were used to assess the contamination levels of the following elements in Yuanping, Shanxi: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), and zinc (Zn). The levels of contamination of these heavy metals in soils were compared to those in street dust, and the difference between the railway’s and mining’s impacts on dust’s heavy-metal concentrations was explored. The results indicated that Cr and Pb in street dust were mainly affected by coal railway transportation, and the interaction effect of coal railway transportation and mining was greater than either of them alone. A potential control and prevention zone for Cr and Pb extending 1 km to both sides of the railway was identified. This work proves that coal railway transportation has certain effect on heavy metals in street dust and provides a scientific approach for future environmental impact assessments of coal transportation via railway.

Prevaluating Technical Efficiency Gains From Potential Mergers and Acquisitions in China’s Coal Industry

With the slowdown of its economic growth, China’s domestic coal industry is facing more and more serious overcapacity. Multiple government departments have jointly proposed that the coal industry should undergo mergers and reorganization to ease this overcapacity, enhance industrial concentration, and optimize production layout. This study thus combines the resample slacks-based measure (SBM) model and potential merger gains model to pre-evaluate the gains from potential mergers and acquisitions (M&As) before making any final decision about them. With a focus on prevaluating efficiency gains before potential M&As instead of efficiency gains after them, we take China’s listed companies in the coal mining and washing industry as the research sample. The data used to evaluate the efficiency from potential M&As come from their annual financial reports from 2013 to 2016. Empirical results show that some mergers of listed coal companies lead to improved efficiency, but not all mergers can bring efficiency improvements. We also find that the most efficient companies are not necessarily the best M&A targets, and that companies suitable for M&As are those in the stage of expansion. In addition, the empirical results confirm that combinations between large coal companies and between cross-listing companies are more efficient.

“…Diagram of the dissociated methanol engine [7] The low heating value of DM is 20% higher than liquid methanol (LM), so that the chemical energy can be further increased after being dissociated, which will result in higher thermal efficiency. China, with vast coal reserves, produces large amount of methanol every year, over 90% of which comes from coal [9]. It is feasible to use dissociated methanol as a type of alternative fuels in combustion engines.…”
