Embodiment 1

[0050] The present embodiment provides a method for evaluating the effect of grouting interception and plugging of a confined aquifer on a mine floor, including the following steps:

[0051] Step 1: Before the grouting treatment, inject water mixed with A isotope into the confined aquifer 5 of the water inrush source to be treated by using the rock mass fissures or joints at the water gushing port, and measure the isotope content in the outflow water at the water gushing port. It is recorded as P%; at the same time, water mixed with other types of isotopes Bi is injected into other water sources in the bottom plate. If isotopes other than A are detected at the water inlet, their content is measured immediately, and they are recorded as Qi% respectively, i=1~ n, where n is a positive integer;

[0052] Step 2: During the grouting process, detect the content of various isotopes in the gushing water at every set time, until the grouting is completed and stabilized, and stop the de...

Embodiment 2

[0080] This implementation also provides a processing device, including at least one processor, and at least one memory communicatively connected to the processor, wherein: the memory stores program instructions executable by the processor, and the processor Invoking the program instructions can perform the method described in Embodiment 1.

Embodiment 3

[0082] This embodiment also provides a computer-readable storage medium, where the computer-readable storage medium stores computer instructions, and the computer instructions cause the computer to execute the method described in Embodiment 1.

Abstract

The invention provides a mine floor confined aquifer grouting interception plugging effect evaluation method and system. According to the invention, water labeled by various different isotopes is injected into each aquifer in a mine roadway by using rock mass fractures or joints, and finally, water plugging effects of confined aquifers are objectively evaluated according to proportions of the different isotopes in gushing water of a gushing port; other potential water inrush water sources which are not found out can be detected by continuously monitoring changes of proportions of all the isotopes in the gushing water, a basis is conveniently and effectively provided for objective and comprehensive evaluation of water stop effects, rapid reaction evaluation of high-pressure dangerous water inrush grouting treatment effects is achieved, and accurate closure of water sources at water gushing positions is further guided; and actual water stop effects after mine water inrush treatment are objectively and effectively evaluated, technical guidance is provided for rapid treatment of floor water inrush accidents of a mine, and closure and plugging effects after water inrush treatment of the gushing port in the mine roadway are conveniently, efficiently and accurately evaluated.

Description

technical field [0001] The invention relates to the technical field of mine water plugging, in particular to a method and a system for evaluating the effect of grouting, interception and plugging of a confined aquifer at the bottom of a mine. Background technique [0002] At present, the methods of grouting water stop or interception are mainly used for the prevention and control of confined water inrush in mines. Such methods have been proved to have practical water stop effects in practical applications, and this type of method not only has the advantages of low cost It also has the characteristics of simple operation, so it is widely used in mine water stop and water blocking. However, in the market, there are few effective methods and means to evaluate the effect of mine water-stopping and blocking. Basically, the water-stopping effect can only be evaluated by monitoring the change of water inflow. This type of method has the following two major problems. First, if the ...
