摘要： 煤柱留设为井下安全开采所采取的安全防护措施，在确保回采安全的同时提升煤柱回收率对于增加矿井综合
收益意义重大。以此为着手点，对煤矿井下提高煤柱回收率技术开展探究。结合具体工程实际，对留小煤柱沿空掘巷及其
支护工艺进行了综合探究，并通过实践数据证明了方案效果良好，希望能够为其他矿井相似工程的开展提供借鉴和参考。

Abstract: Coal pillar setting is a safety protection measure for underground safe mining. It is of great significance to increase the
comprehensive income of the mine to improve the recovery rate of coal pillar while ensuring the safety of mining. Taking this as
the starting point, this paper explored the technology of improving coal pillar recovery rate in underground coal mine. Combined
with the specific engineering practice, it made a comprehensive research on gob-side entry driving with small coal pillar and its
supporting technology, and proved that the scheme had good effect through practical data, hoping to provide reference for similar
projects in other mines.

Key words: mine; small coal pillar; thick seam mining; recovery rate; gob-side entry driving
