| 摘 要： | 巷道穿采,本质上是一种窄条带的特殊开采方法.作为传统建下煤柱开采方法的补充,适用于浅部建下压煤开采,已经成功地运用在实践中.该方法投入少,生产系统简单.但其巷道支护方法、回撤扩帮方法和采留比设计等,仍是巷道穿采中值得深入研究的问题.

| Abstract: | Extraction through tunnel, as a supplement of traditional mine coal with coal pillar under buildings, is a kind of special coal mine with narrow strip which is suitable in mine coal with shallow pillar under buildings and has been successfully utilized in practice. This method with a simple production system, is of lower cost But problems such as methods of tunnel support and feedback and expanding roadway, and designs of ratio of extraction to reservation, should be still studied in the extraction through tunnel. |
