摘　　要：本文以干河煤矿团柏河地区水下采煤为例,基于岩层变形破坏理论,计算得到干河煤矿团柏河地区水下采煤1#、2#煤层的煤岩柱厚度。结合水文地质条件,通过对比最大保护煤岩柱高度和地下水位,对团柏河地区水下采煤工作的安全性进行论证,为团柏河地区的水下采煤工作提供理论的支撑。This paper takes the underwater coal mining in Tuanbaihe area of Ganhe coal mine as an example. Based on the deformation and failure theory of rock strata, the thickness of coal and rock pillars of No.1 and No.2 coal seams in the underwater coal mining in Tuanbaihe area of Ganhe Coal Mine is calculated. Combined with hydrogeological conditions, the safety of underwater coal mining in Tuanbaihe area was demonstrated by comparing the maximum protection height of coal pillars and underground water level, which provided theoretical support for the underwater coal mining in Tuanbaihe area.
