| 岩石种类 | 孔隙度 | 理想分割阈值 | | 膏岩 | 26.26% | T=g2+(g1-g2)×0.9=0.9×g1+0.1×g2 | | 泥岩 | 26.62% | T=g2+(g1-g2)×0.9=0.9×g1+0.1×g2 | | 煤 | 0.51% | T=g2+(g1-g2)×0.1=0.1×g1+0.9×g2 | | 泡沫混凝土 | 28.58% | T=g2+(g1-g2)×0.6=0.6×g1+0.4×g2 | | 油页岩 | 14.7% | T=g2+(g1-g2)×0.4=0.4×g1+0.6×g2 | | 砂岩 | 15.11% | T=g2+(g1-g2)×0.6=0.6×g1+0.4×g2 |
