Problems solved by technology
For mines that are converted from open pits to underground mines using the pillarless segmented caving method, due to the large catchment area of the open pit, a large amount of rainwater will flow into the underground through the covering rock formation during rainfall, which may easily cause safety accidents such as underground debris flow and well flooding

Description
technical field [0001] The invention relates to the mining field of bottom-pillar-less segmental caving in open-pit-to-underground mines, and in particular to an experimental system device for simulating water seepage in overlying rock formations. Background technique [0002] After years of mining, some open-pit mines in our country have gradually transferred to underground mining. For mines that adopt the sub-pillar caving method from open pit to underground, due to the large catchment area of the open pit, a large amount of rainwater will flow into the underground through the overlying rock formation during rainfall, which may easily cause safety accidents such as underground debris flow and well flooding. Therefore, it is of great significance to study the law of water seepage in overlying rock formations for the safe production of open-pit to underground mines. In order to study the law of water seepage in the overburden strata, we need an experimental system device ...
