Embodiment Construction

[0050] Such as figure 1 Shown, the present invention's shallow buried coal seam mine ditch flood flood prevention and control method is characterized in that the method comprises the following steps:

[0051] Step 1. Determine the drainage area F of the upstream channel of the working surface of the shallow coal seam to be built with a water retaining cofferdam: firstly, conduct field surveys on the affected area of ​​the surface of the shallow coal seam to determine the location of the water retaining cofferdam to be built; then, use satellite ground Remote sensing images or surface elevation data determine the distribution characteristics of surface watersheds, determine the water catchment range upstream of the water retaining cofferdam to be built on the surface of the shallow coal seam working face, and obtain the channel drainage area F upstream of the water retaining cofferdam to be built;

[0052] Step 2. According to the formula Calculation of the flood flow Q upstr...

Abstract

The invention discloses a preventing and treating method for a flood inrush water disaster in a shallow buried coal seam mine channel. The preventing and treating method comprises the steps that (1) the drainage area F of an upstream channel of a water retaining cofferdam to be constructed on the surface of a working face of a shallow buried coal seam is determined; (2) the upstream flood flow QN of the water retaining cofferdam to be constructed with the recurrence period being n years is calculated; (3) the normal flood flow Q' of the mine surface channel is obtained; (4) a water guiding pipeline of the water retaining cofferdam to be constructed is constructed, and the water retaining cofferdam is constructed; (5) a temporary artificial diversion open channel is constructed; (6) crack filling is conducted; and (7) a permanent artificial diversion open channel is constructed. The preventing and treating method is novel in design and simple in step, and can provide a flood preventing and treating method for the surface channel in three different periods of before stoping, stoping and after stoping of the shallow buried coal seam working face, so that unnecessary waste in the mining process of coal resources can be reduced, and the mine water disaster can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of mine trench flooding, and in particular relates to a method for preventing and controlling flood flooding in shallow coal seam mine trenches. Background technique [0002] With the westward shift of my country's coal resources development strategy, in recent years, the problem of mine water hazards encountered in large-scale mining of coal resources in the west has become increasingly prominent. Among them, in the area where the coal seam is buried shallowly and the surface trenches and their tributaries are developed, the collapse zone and fracture zone formed in the overlying strata after coal seam mining will reach the surface directly, forming relatively wide cracks on the surface. , it may cause the ditch flood to collapse into the underground and cause water damage accidents. Therefore, in coal production, it is necessary to study the prevention and control of water damage through ditch mining. At ...
