Abstract

The invention relates to a mining model, in particular to a filling mining model after section-wise drilling flat bottom ore removal. The mining model comprises an overground part and an underground part, an all tailing bin and a cement bin of an upper part of a mine filling system are connected with a to-be-filled room by a filling pipeline, two filling drill holes are formed in the top of an artificial platform above the to-be-filled room, the filling pipeline is communicated with the to-be-filled room by one of the drill hole, a photoelectric demonstration system is arranged in the to-be-filled room, a ventilation way shaft is arranged on one side of the to-be-filled room and is communicated with an in-mining room and the artificial platform respectively, the in-mining room is in a salvo blasting manner with an upper section in ahead of a lower section, and the room is in a V-shaped structure. With the adoption of the technical scheme, ground pressure management is easy, and sudden-onset disasters occurring in the mining process are effectively controlled; the specific filling process is demonstrated, the specific process from the start to the end of the filling process is demonstrated with a photoelectric combined method.

Description

technical field [0001] The invention relates to a mining model, in particular to a segmented rock-drilling flat bottom mining model followed by filling. Background technique [0002] At present, the entire national economy has entered a period of rapid development, and the mining economy has also improved accordingly. But we also see that the existing mining methods can no longer meet the needs of current social development. Its mining efficiency is relatively low, serious mineral loss, environmental pollution and many other unfavorable factors have hindered the sustainable development of our country's ecological economy. [0003] Therefore, a more practical mining process method has been paid attention to - mine filling mining method. This method has many advantages in actual mine production, for example, it is beneficial to exploit deep mines, deposits under water, buildings and structures, and deposits with spontaneous combustion tendency. It has high mining recovery r...
