Outer-masonry and inner-concrete artificial pillar and construction method thereof

The invention discloses an outer-masonry and inner-concrete artificial pillar and a construction method thereof. The outer-masonry and inner-concrete artificial pillar comprises a pillar body, wherein the side wall of the pillar body is formed by piling rubbles; the pillar body is internally filled with concrete; the top of the pillar body is filled with foamed concrete. The construction method comprises the following steps: sequentially clearing or manufacturing a foundation, building a rubble wall, pouring concretes and molding on the top around an ore pillar original location or a preserved native ore pillar, thereby finishing construction of the outer-masonry and inner-concrete artificial pillar. The construction method has the following advantages that: the use amount of concretes and shuttering processes are reduced and the cost is lowered; the ore recover ratio is improved, the support stability of a goaf is enhanced, the disturbance influence of underground mining on the surface environment is reduced
