The invention discloses a method for preventing accumulation of downhole floating coal of a coal mine. Firstly, the amount of accumulated coal produced by the fact that flowing water scours a laneway is reduced from a source; secondly, a plurality of sedimentation tanks are arranged at different positions of a working area so as to carry out fractionated precipitation and purify the water in the mine; and finally, a large-diameter precipitation-preventing glass steel tube is paved in a large horizontal laneway so as to replace a conventional concrete water channel. The method totally solves the problem that overflow water in the mine leads to silt coal, reduces the water accumulated in the laneway and ensures the water capacity of a dibhole.
Description
technical field [0001] The invention relates to underground drainage technology of coal mines. Background technique [0002] At present, in coal mining, some coal mines have a large amount of water gushing underground, and a large amount of gushing water carries floating coal and deposits in the ditch of the road, the water tank in the mining area and the horizontal water tank, often causing water accumulation in the roadway, which brings inconvenience to the pedestrians , so that the effective volume of the horizontal water tank of the mine and the water tank of the mining area are reduced, and the water storage capacity is reduced, and frequent dredging is required. Solving the problem of mine water silt coal has become a problem that must be solved in coal mine water prevention and control work. Contents of the invention [0003] The invention proposes a prevention and control method for solving the problem of floating coal deposition caused by water gushing undergroun...
