Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] With reference to the accompanying drawings, the method of the present invention based on filling the sky and taking surface waste rocks to treat the goaf: when the thin bedrock 1 and the shallow buried goaf 2 are treated after mining, the full-section drilling method is adopted from the surface 3 by a drilling rig Drill down a plurality of raised wells 4 to goaf 2, and then take waste rock 6 on the surface to fill the goaf 2 by freely falling; The free fall of waste rock 6 on the surface; because the waste rock 7 freely falling through the same patio 4 cannot fill the goaf 2, in order to fill the goaf 2 as much as possible, at least three patios 4 must be drilled downward on the surface; At the same time, the surface waste rock 6 must be crushed so that it can be directly and freely dropped into the goaf 2 .
[0014] In this way, after the goaf...
