Abstract

The invention provides a curtain closure method for a submersible aquifer dotted vertical water guiding channel. The curtain closure method comprises the following steps of: drilling holes: drilling aplurality of holes within a preset radius range around the dotted vertical water guiding channel, and after the centers of the plurality of holes are connected, surrounding the dotted vertical waterguiding channel in connection lines; and grouting: injecting mortar into the holes, and after the mortar is solidified, obtaining an anti-seepage curtain. According to the above scheme provided by theinvention, an entrapment type curtain body is constructed around the aquifer dotted vertical water guiding channel so as to cut off a submersible aquifer supply water source, a mine water inflow is reduced, water disaster hidden dangers are eliminated, and meanwhile, cost input is greatly saved.

Description

technical field [0001] The invention relates to the technical field of water prevention and control in coal mines, in particular to a method for curtain interception of dotted vertical aqueducts in submerged aquifers. Background technique [0002] Coal mine water damage has always been one of the main disasters restricting the efficient and safe development of coal in my country. During the mining of shallow coal seams in Northwest my country, due to the collapse of the goaf, it is easy to form point-shaped vertical water-conducting channels, which are connected to the upper phreatic aquifer, causing the phreatic water to flow into the underground. Threatening the safe production of mines, therefore, the management of vertical water guide channels is one of the key tasks in the prevention and control of shallow buried deep coal mines. [0003] For the treatment of this type of point-shaped aqueduct, direct grouting is usually used at present to block the measures. Due to the...
