Abstract: Abstract In multiple seam coal mining, the fractures induced by the mining of the lower coal seam may propagate to the goaf of the upper coal seam that is mined earlier. The fracture connection leads… read more here.

Abstract: Abstract The first phase in the stepwise collapse of the Carboniferous Coal Forests occurred near the Desmoinesian–Missourian boundary (early Kasimovian, ~ 307 Ma), and involved extirpation of Lycospora-producing lepidodendrids, and some other lycopsids, across most of tropical… read more here.
