Tectonically Altered Coal Rank, Boulder Creek Formation, Northeastern British Columbia
Fieldwork during the 1988 season involved investigation of the thermal affects of tectonic movement on vitrinite reflectance near the Quintette Coal Limited mining operation in northeastern British Columbia. Two samples, collected in 1987, from the same seam on either side of a fault, suggested a significant rank increase associated with the stmctwe. These sites were revisited and sampled toget...
متن کاملThe 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 کاملHealth of Children Living Near Coal Ash
Coal ash, generated from coal combustion, is composed of small particles containing metals and other elements, such as metalloids. Coal ash is stored in open-air impoundments, frequently near communities. The objective of this study was to evaluate the prevalence of health and sleep problems in children living near coal ash and compare these prevalences to children not living near coal ash. In ...
