“…This is because they retain some chemical features of biotite, such as higher contents of iron and magnesium and lower content of silicon. The ferrous cation preferentially occupies M2 sites and there are few, if any, ferrous cations in the M1 site 9 . See Table 4 for the iron distribution in different crystallographic sites.…”

The formation of glauconite from the Chinese Yellow Sea and the Chinese Eastern Sea was studied by the use of Mo¨ssbauer spectroscopy. The process of glauconite formation appears to differ between the respective seas, due to different initial substances of the formation. The results show the valence states and the crystallographic sites of the iron cations, and suggest that there may be a correlation between the formation process of glauconite and Mo¨ssbauer parameters.

Muling River, situated amidst cultivated lands in Heilongjiang Province, northeastern China, has long been subjected to sand‐digging activities, resulting in severe damage to its riverbed. However, little research has been conducted on the impact of this disturbance on the status of fish community structure and trophic guilds in this river. In this study, environmental factors, fish community structure, and fish trophic guild biomass distribution patterns from the Muling River basin were investigated among seasons (spring, summer, and autumn) and sections (upper, middle, and lower stream) in 2015 and 2017. During the six sampling times periods, 46 species of five orders and 12 families of fish were classified into seven trophic guilds. Fish species number and biomass were higher upper reaches of the watershed. The insectivores (16.26%), phytoplanktivores (10.09%), benthivores (40.17%), and omnivores (11.86%) were the dominant trophic guilds. We found that fish trophic guilds biomass and environmental factors such as transparency, water depth, pH value, total phosphorus, and chemical oxygen demand were highest in the upper section compared to other sections. Variation partitioning revealed that fish trophic guilds biomass was influenced more by environmental factors (61.2%), followed by section (0.7%) and season (0.1%). Partial RDA ordination showed that fish trophic guilds were positively correlated with water depth and transparency, while negative with turbidity. This study underscores the importance of considering trophic guilds of freshwater fishes to inform management strategies in regions experiencing significant environmental change.

“…Application conditions. According to information of various aspects and field research [3], the continuous miner is suitable for the mine that buried depth is less than 500m, thickness of coal seam is 1.3~4.0m, dip angle of coal seam is less than 12°, stability of roof is moderate or above, the allowed exposed area of roof must be more than 50m 2 , rock bolting can be used, compressive strength of floor can't be too low. Mine or coal seam that does not all accord with the above conditions, continuous miner used in room and pillar mining method can also be used, the United States, Australia and China all have instances.…”

In order to solve the problem of coal mining under villages of regions of Yaoqiao Mine, through comprehensive analysis, the author considers that strip mining has feasibility in realistic, meanwhile, a series of mining width and retaining width was studied for strip mining and eventually a mining project was put forward to meet the unique conditions. By comparing application conditions and range of application between continuous miner used in strip type of Wongawilli coal mining method and shortwall shearer mining method, the author analyzes the economic benefit and draws a conclusion that shortwall shearer mining method has better applicability. Those all provide a new way to mining under villages in Yaoqiao Mine and the conclusion can also be used for reference in similar mining conditions.
