Novel water control method suitable for mine shafts

Abstract

The invention relates to a novel water control method suitable for mine shafts, which is characterized by firstly adopting grouting for water plugging at a water-bearing layer at the upper part of the shaft; arranging a wall seat at the boundary of the water-bearing layer and a water-resisting layer and arranging a bypass for water interception after the wall on the upper surface of the wall seat; arranging a dewatering orifice in the bypass and arranging a water guide pipe in the orifice, wherein the wall seat is wider than the bypass and the wide part of the wall seat is upwarped for water blocking; arranging a water collecting ring in the shaft at the upper part of an access road and draining water collected by the water collecting ring into the bypass after the wall, wherein a baseplate of the access road is 200-300mm higher than the bypass; and pre-burying a drainage pipe and enabling gushing water collected at the upper part of the bypass to self-flow into a water sump and be further drained to the ground through a drainage device. By adopting the novel water control method, the construction conditions of the mine shaft can be improved, the construction quality can be improved and the progress can be accelerated; furthermore, water damages can be effectively prevented during the production period of a mine, the safety of the mine shaft is protected, the drainage cost is reduced and the service life of the mine shaft is prolonged.

Description

Technical field [0001] The invention relates to a method for preventing and controlling water in mines, in particular to a novel method for preventing and controlling water in mine shafts. Background technique [0002] At present, the main measures to prevent water in mines in my country include ground pre-grouting, curtain grouting, working face filling grouting, and freezing construction. These measures are mainly used in the construction of the shaft during the construction period. The adoption of the above water prevention measures is of great significance to speed up the construction of the mine and improve the quality of the project; however, water leakage occurs in the production process after the completion of the shaft construction, which affects the safety of the shaft and shortens the mine. Service life; in addition, a large amount of seepage water enters the underground roadway or stope along the inner and outer sides of the shaft wall, which greatly increases the di...

These measures are mainly used in the shaft construction process during the construction period. The above water prevention and control measures are of great significance to speed up mine construction and improve project quality; however, water leakage occurs in the production process after the shaft construction is completed, which affects the safety of the shaft and shortens the length of the mine. Service life; In addition, a large amount of water seepage enters the underground roadway or stope along the inner and outer sides of the well wall, which greatly increases the difficulty of drainage, especially the mining of soluble salt deposits poses a safety hazard
