倾斜煤层综采沿空留巷技术研究

Research on Gob-side Roadway Retaining Technology in Fully Mechanized Mining of Inclined Coal Seams

以倾斜煤层综采沿空留巷技术为对象开展探究,在分析沿空留巷支护设计的基础上,通过数值模拟手段对设计方案使用效果做出检验。结果表明,所设计的方案在确保了巷道使用安全的同时,提高了井下煤炭回采率,为矿井综合效益的提升提供了有效保障。

This paper explored the gob-side roadway retaining technology in the fully mechanized of inclined coal seams.Based on the analysis of the supporting design of gob-side roadway retaining,this paper used the numerical simulation method to test the effect of the designed scheme.The results showed that the designed scheme improved the recovery rate of underground coal while ensuring the safe use of the roadway,and provided an effective guarantee for the increase of comprehensive benefits of the mine.
