— Authors have divided its developing process into three stages: rapid growth of coal industry (1979–1992); close-down of small-scale coal mines (SCMs) (1993–2001); resource consolidation (2002–present). At the first stage, led by the 'two-leg walking' strategy, SCMs grew significantly, which eased the pressure of energy shortage.
