Abstract: The efficiency and safety of underground roadway support directly affect the safety of underground fully mechanized
mining. At present, most coal mines' gob-side entry retaining schemes under complex geological conditions adopt the similar
schemes unter conventional geological conditions or rely on the experience of the operators to support, which is not only inefficient,
but also prone to the instability of the support, having a serious impact on the underground support safety. This paper put
forward a new supporting scheme of gob-side entry retaining under complex geological conditions. This scheme took the roadside
support and filling support as the core, and reasonably configured two supporting schemes, which not only effectively reduced the
difficulty of supporting operation, but also improved the efficiency and safety of supporting operation. The practical application
shows that the comprehensive control scheme has the advantages of high control stability and good economy, which greatly
improves the safety and stability of the underground support operation.

Key words: gob-side entry retaining; filling support; roadside support
