Pillar Extraction using Continuous Miners underground COAL
网页Some methods of pillar extraction using continuous miners are: Pillar splitting where roadways are driven through the pillars formed on first workings; the remnant pillars left would not normally be stable over extended areas. In some cases "pockets" are driven into the pillars with no supports rather than drive roads fully through.
