广西合山煤田,在无产阶级文化大革命前,在深部地区未作任何地质揭露工作的情况下,结论都说:煤层由浅部向深部变薄,煤质变劣,含煤程度不高,水文地质条件复杂。还有人认为,广西上二迭统浅海碳酸盐相无煤层沉积的可能性,有煤层沉积也是局部的,无大工业价值。因此,合山煤田深部地区不宜进行大规模的地质勘探工作。这种唯心主义、形而 Heshan Coalfield, Guangxi, before the Great Proletarian Cultural Revolution in the absence of any geological exposures in deep areas, concluded that: the coal seam from the shallow to the deep thinning, poor coal quality, coal is not high, hydrogeology Complex conditions. Others think that there is a possibility that sedimentary deposits of coal in the upper Permian carbonate zone in the Upper Permian in Guangxi are partial and have no big industrial value. Therefore, the Heshan coalfield deep area should not be large-scale geological exploration work. This idealism, shaped and
