Rehabilitation Counseling Bulletin | Year: 2011

The present study is aimed at examining implicit and explicit attitudes toward persons with disabilities among Chinese college students. The Implicit Association Test was used to measure their implicit attitudes, whereas their explicit attitudes toward persons with disabilities were measured by using a scale of three items. Participants were 56 randomly recruited undergraduate students at a university in Beijing. The results showed that implicit and explicit attitudes were antagonistic to each other. Students tended to hold negative attitudes implicitly and positive attitudes explicitly toward persons with disabilities. In particular, students from rural areas exhibited more negative implicit attitudes than those from urban areas; males demonstrated more negative explicit attitudes than females. Implications for rehabilitation counselors are discussed. © Hammill Institute on Disabilities 2011. Source

Based on the latest research results from the project of Chinese potential coal resource estimation and previous studies, the geological and administrative district distribution laws of total sulfur and the forms of sulfur in Chinese coals were discussed using the calculation method of weighted average of recoverable deposits. Furthermore the geological causes which impacted on the sulfur content were discussed. The results show that the range of sulfur content in the coals of China is relatively wide and the special low sulfur coal and low sulfur coal account for a large propotion. The weighted average of recoverable deposits of sulfur in Chinese coals is 1. 14%. Total sulfur content of the Late Permian, the Early Carboniferous and the Late Carboniferous coal is higher, while that of Early to Middle Jurassic coal is the lowest. The weighted average of recoverable deposits of sulfur in coals of southern China coal-forming area is the highest while that of western China coal-forming area is the lowest. Furthermore, bounded by Zhejiang, Jiangxi, Chongqing and, Guangxi, the sulfur in coal gradually increases and then decreases from northwest to southeast. The high organic sulfur coal is mainly distributed in Late Permian coal in southern China and in Late Carboniferous coal in northern China. The sulfur content in coal is closely related to the sedimentary environment. The sulfur content in coal which influenced by seawater is higher. It is also higher in case that the coal formed in marine-terrigenous depositional environment. While formed in continental sedimentary environment, the sulfur in coal is lower. The results provide a basis for a rational arrangement in coal exploitation and utilization. © 2015, China Coal Society. All right reserved. Source

Due to the complicated geological conditions and the differences of physical geography conditions in China, it is difficult to solve the exploration problems with single exploration technique. According to coal geological characteristics and coal industrial requirements in China, innovative ideas and theoretical system of coal geological comprehensive exploration are proposed in this paper. The system can be summarized as "one innovative idea and two supporting theories". One innovative idea is the comprehensive exploration. Two supporting theories are the coal accumulating theory and the tectonic controlling theory of coalfield. The innovative ideas and theoretical system of coal geological comprehensive exploration provide theory and technique support for coal mine construction, improve support ability of coal resources of our country and are of great significance in coal industry sustainable development.

Analysed the sequence stratigraphy and palaeogeography of the early and early middle Jurassic coal measures in the Junggar Basin, northwestern China. The controls of the palaeogeography and sequence stratigraphy on the coal accumulation in this basin was discussed. The results show that, the coal measures were formed in a fluvial-delta-lacustrine sedimentary system, and a total of 3 third-order sequences were developed, corresponded to Badaowan Formation(J1b), Sangonghe Formation(J1s) and Xishanyao Formation(J2x). The Junggar Basin had experienced the swamping (Sequence I)-lake flooding (Sequence II)-swamping (Sequence III) processes. The thick coal seams were developed at the late transgressive systems tract and the early highstand systems tract and near the maximum flood surface, when the rate in creation of accommodation kept balance with the peat accumulation rate. Sequence I and sequence III's coal-forming environments are floodplain swamp, the delta plain and the shallow lake, especially delta plain best. Source

The authors studied the depositional environments, sequence stratigraphy, paleogeography and coal accumulation of the Carboniferous-Permian paralic coal measures based on data from outcrop and borehole sections. The sequence boundaries were represented by regional disconformity, transgression direction switching surface, the base of incised valley fill sandstone, facies-reversal surface and associated paleosols. According to these sequence boundaries, the coal measures were subdivided into 7 third-order sequences and related systems tracts. For the paleogeography analysis, the contours of a variety of lithofacies parameters were drawn, including strata thickness, thickness ratio of sandstone and mudstone, limestone contents, and coal thickness. Based on these contours, the lithofacies paleogeography maps of each third-order sequence were reconstructed. The comparison of the contours of coal thickness with the distribution of facies units of the lithofacies paleogeography was made, and it revealed that the favorable coal-accumulating environments were deltas, fluvial plain and lagoon-tidal flat. Coal accumulation was strong in SQ2 (middle and upper Taiyuan Formation) and SQ3 (Shanxi Formation) with the coal accumulating centers were distributed in the Zhungeer, Datong, Shuozhou, Wuhai, Fengfeng areas, and the Beijing-Tainjin-Tangshan area. Coal accumulation in SQ4 (Xiashihezi Formation) and SQ5 (first member of the Shangshihezi Formation) was weak and the coal-accumulating centers were distributed in the southern part of the North China Basin, including Huainan and Huaibei coal fields.
