Abstract

The invention provides an underground reservoir system of a sealed mining area. The system comprises mine column dam bodies on the two sides, an artificial dam body and a water insulation membrane composite plate which are arranged between the mine column dam bodies arranged on the two sides, the artificial dam bodies are composed of multiple concrete bricks, the water insulation membrane composite plate is arranged on the side, close to the reservoir, of the mine column dam bodies, the concrete bricks are produced by a manufacturing instrument of the concrete bricks, and the manufacturing instrument at least comprises a concrete brick mold. When the artificial dam body and the water insulation composite plate are installed, wall caving is conducted on the mine column dam bodies on the twosides firstly, mine column cutting is conducted mine column dam bodies to provide space for installing the water insulation composite plate, grouting reinforcing is conducted on the water insulationmembrane composite plate, finally the artificial dam body is installed, and a mine column cutting device is used for cutting the mine columns. The system has the advantages that the problems of waterseepage and leakage caused by top plate breaking and the existence of an insulation layer above a top plate are solved.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to an underground reservoir system for sealing mining areas. Background technique [0002] In coal mining, storing underground water resources, constructing coal mine underground reservoirs, and storing water through pumping pipes is very important for the protection of water resources and the coordinated development of coal resources in the water-scarce regions of the west. [0003] The underground reservoir is built on the goaf after coal mining. The dam body of the underground reservoir is the leftover coal pillar and the artificial dam body built between the coal pillars. The most important and the largest workload in the construction process of the entire underground reservoir The most important thing is the construction of artificial dams. [0004] The current artificial dam is designed and built underground according to the requirements, and the main materials are built layer by la...
