| Abstract: | Based on the experimental and analytical research on the quality of sublevel stopes Coalrock pillar against water, the feature of waterbearing and insulation under the ravelly stratum, the authors prove the possibilities of enhancing the upper limit, reducing the hight of coal pillar 17m and retrieving 46.000 tons of original unrecovery coal. |
| Keywords: | sublevel caving coalrock pillar against water upper extraction limit |
