| 摘 要： | 在对里彦煤矿采矿地质条件分析的基础上,对安全煤岩柱的化学成分及其阻水性能、岩性及力学特征进行了研究.针对里彦煤矿的具体情况,分析了里彦安全煤岩柱的阻水性能,认为其阻水性能良好,可以适当减小防水防砂煤岩柱宽度,以提高开采上限,释放部分煤炭储量. |

| Abstract: | Based on the analysis of geological mining condition in Liyan Mine,those properties of coal and rock pillar for safety are studied,including chemistry component,its water-proof capability and lithology and mechanic characteristics.Aiming at special instance of Liyan Mine,the water-proof capability of coal and rock pillar for safety of Liyan Mine is analyzed.The capability is deemed to be better,and the width of pillar for water-proof and sand-proof can be decreased,which can heighten upper limits of mines and release caol reserves. |
| Keywords: | coal and rock pillar for safety weathering zone safeguard layer water-proof capability |
