Embodiment Construction
[0037] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0038] The following will take the underground stope as an example to describe in detail the construction method of the artificial pillar itself and the bearing structure. It can be understood that the artificial pillar of the present invention can not only be used in underground stopes, so the description about underground stopes does not constitute a limitation of the present invention, and those skilled in the art can understand the relevant technical characteristics of underground stopes as other Corresponding features of underground works.
[0039] Such as figure 1 As shown, the underground engineering artificial pillar of the present invention includes an integrally cast bearing structure 6 and self-expanding roofing structures 10 , 11 , 12 . The constr...
