The action of anthracite and bituminous coal dusts mixed with quartz on the lungs of rats.
Belt and King (1945) studied the tissue reactions produced in animals by selected dusts from South Wales coal mines, and found that clean coal (low ash coal fraction containing 99% coal) produced only minimal fibrosis (grade 1) with simple foreign body reaction in 250 to 500 days. In experiments with high ash coal fractions which contained from 37 to 66% coal and about 1 to 3% quartz, the rest ...
متن کاملAdsorption Capacity for Phosphorus Comparison among Activated Alumina, Silica Sand and Anthracite Coal
Experimental researches on adsorptive capacity of activated alumina, silica sand and anthracite coal for phosphorus were conducted. Results showed that performances of three filter media were all in line with Langmuir isotherm, and activated alumina adsorptive performance was much better than silica sand and anthracite coal for phosphorus removal. The adsorptive capacity of activated alumina, s...
متن کاملStructural Dislocations in Anthracite
C nanomaterials promise to find many applications in areas that include electronics, photonics, energy, and sensing. Graphene occupies an important position in this emerging area. In view of our interest in the synthesis of soluble carbon nanotubes 7 and graphene, we have investigated routes to other soluble materials that have a high carbon content. Anthracite is of interest in this regard, as...
متن کاملA synchrotron-based local computed tomography combined with data-constrained modelling approach for quantitative analysis of anthracite coal microstructure
Quantifying three-dimensional spatial distributions of pores and material compositions in samples is a key materials characterization challenge, particularly in samples where compositions are distributed across a range of length scales, and where such compositions have similar X-ray absorption properties, such as in coal. Consequently, obtaining detailed information within sub-regions of a mult...
متن کاملComprehensive Technical Support for High-Quality Anthracite Production: A Case Study in the Xinqiao Coal Mine, Yongxia Mining Area, China
The effective production of high-quality anthracite has attracted increasing global attention. Based on the coal occurrence in Yongxia Mining Area and mining conditions of a coalface in Xinqiao Coal Mine, we proposed a systematic study on the technical support for the production of high-quality anthracite. Six key steps were explored, including coal falling at the coalface, transport, undergrou...
