I understand now that 'met' coal and 'anthracite' coal are not synonymous, since met coal production in BC Canada is a huge industry and anthracite is not anticipated to be mined there until 2016 (or later if the usual permitting delays and environmental lawsuits, etc... delay it further). That admitted, there is in fact something that is being referred to as "anthracite coal" in British Columbia Canada, and they are clearly not calling it semi-anthracite. The title for this thread should therefore have been: "What's the difference between BC Anthracite and PA Anthracite?"
Some info I scarfed directly from the Fortune Minerals Limited website:
ABOUT ANTHRACITE COAL:
Mount Klappan has very large resources of high quality anthracite metallurgical coal, the highest rank coal based on carbon and energy content. Anthracite is used in a broad range of applications, including reductants used in metallurgical processing, blend coals for blast furnace coke replacement, and charge carbon, sinter and PCI coals used to manufacture steel. Only about 1% of world coal reserves are anthracite grade, making Mount Klappan coal a relatively uncommon premium product. Global annual anthracite production is approximately 565 million tonnes with 85% of supply currently produced in China, which notably became a net importer in 2008. Vietnam, the world's second largest producer with annual production of approximately 43 million tonnes, is curtailing exports in order to satisfy domestic requirements. Mount Klappan is well positioned to service the growing demand from the growth of emerging economies, primarily in Asia and constrained supply.

This is apparently as good as it gets in British Columbia, CA. How does this compare with typical PA Anthracite? I was thinking that the carbon content is a bit low compared to nominal PA anthracite, so by PA anthracite standards, perhaps this BC coal is only semi-anthracite after all? When the mine starts up in 2016 it's all going to go into Asian steel manufacture, but would it burn in our stoves? It would be sad to see all of this high quality coal going to Asia for steel production if it can be burned in stoves and boilers across America (meaning here both Canada and the United States).
