Embodiment Construction
[0032] refer to figure 1 , a method of using anchor cables to assist in plugging water inrush in a mine, comprising the following steps in sequence:
[0033] 1) Determine the construction location: After water inrush occurs in the mine, in the process of emergency rescue, according to the grouting water blocking plan, comprehensively consider the location of the water inrush point, the required length of the water blocking section of the roadway, the integrity of the surrounding rock of the roadway and the surface interception drill The position of the through-hole of the hole determines the position of the outer end of the water-blocking wall. The greater the hydraulic pressure of the flowing water after closure, the longer the length of the water-blocking section; The distance is much smaller than the distance between the outer end of the aggregate wall and the water inrush point after the aggregate is diffused;

The invention relates to a method for auxiliary blocking of mine inrush water by using anchor cables. The existing method is only applicable to the smaller-water-inrush-quantity and lower-water-pressure condition, and has poor applicability for huge-water-inrush-quantity and higher-water-pressure super-huge type mine inrush water. The method for auxiliary blocking of mine inrush water by using the anchor cable comprises the following steps of selecting a position, i.e., a section perpendicular to the axis of a roadway; putting a mesh; constructing a ring of anchor cable holes in a top plate, a bottom plate and two lateral walls of the roadway on the section; quickly installing a tray, a lock or a clamp of the anchor cable, and sleeving a horse-shoe collar between the two locks; sleeving a steel wire rope in the horse-shoe collar; correspondingly connecting anchor heads by the steel wire rope along the horizontal direction and the vertical direction; fixing the mesh on a grid of the steel wire rope by turns of wires; tightening the steel wire rope at a sealing part after the mesh is fixed. According to the method provided by the invention, the amount of aggregate can be reduced by tens thousands square meters, and also the corresponding dredging amount is reduced; the time of water plugging engineering and dredging and mine recovery can be reduced by 1 to 2 months above.
Description
technical field [0001] The invention belongs to the technical field of mine water plugging, and in particular relates to a method for auxiliary plugging of mine water inrush by using anchor cables. Background technique [0002] After a large water inrush occurs in the mine, in order to ensure the safety of the upper production system of the mine and the adjacent mines, forced drainage is often used to control the submerged water level in the mine. In general, the method of dynamic water interception in the roadway is to inject aggregates on the ground through drilling holes. The aggregates are generally sand, rice stone and gravel. Relying on the aggregates to build a water-blocking section in the roadway, gradually reduce the water flow in the roadway , and finally inject cement slurry to completely block the roadway, and then carry out grouting treatment to the water inrush channel in the formation under still water conditions. [0003] At present, the mine dynamic water ...
