The European coal curse SpringerLink

2021-3-4  In this paper we examine the impact of natural resource wealth by focusing on historical coal-mining across European regions. As an exogenous source of variation in coal extraction activities, we rely on the presence of coal-deposits located on the earth’s surface, which historically facilitated the discovery and extraction of coal. Our results show that former coal-mining regions are ...

USGS Bulletin 1823 - Sampling of Coal Beds for Analysis

In surface mines, a gamma-ray scintillometer (a hand-held instrument) is used to locate impure layers in low-ash coal. For the drill core, an X-ray radiograph and a gamma-gamma (density) down-hole geophysical log can be compared with the coal core. For sample collection from deep mines, no comparable instrument that is "mine safe" is available.
