post-pillar mining mining.

Добрый день!
Очень прошу специалистов подсказать как называется такой вид разработки как post-pillar mining.
Вот его описание:
Post-pillar mining is a cross-breed of room and pillar and cut and fill stoping. Post pillar mining recovers the mineralisation in horizontal slices, starting from a bottom slice, advancing upwards. Pillars are left inside the stope to support the roof. The mined-out stope are back filled with hydraulic tailings and the next slice mined by machines, working from the fill surface. Pillars are extended through several layers of fill and the fill is contributing to the pillar's supporting ability.
