Hypothesis of the multiple subsidence trough related to

高达10%返现 Coalfields in the north of Spain (Asturias) are mainly steeply dipping and at considerable depth. There is widespread use of caving mining methods at the present time. This paper describes a theory developed to predict the subsidence related to very steep and nearly vertical coal seams (70°–90°). This ‘theory of the multiple subsidence trough’ is applied through a new profile
