This method can only detect the water quality information at the section of the roadway. Due to the influence of the position of the roadway and the filling body, it cannot guarantee that the water quality at the section of the roadway is the seepage of the filling body, and it cannot determine the degree to which the water quality is affected by the seepage of the filling body.

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] This embodiment is the subsequent filling method of mining ore bodies in a heavy metal mine.
[0035] combine figure 1 , the filling body 1 is 20m long along the strike, the height b is 40m, the ore body dip angle β is 80°, and the width c is 10m.
[0036] For the subsequent filling mining of this mine, the water quality of the groundwater after seepage through the filling body should be monitored, so that measures can be taken in time for remedial measures when pollution occurs.
[0037] combine Figure 1 to Figure 3 In this embodiment, the method for dynamic monitoring and prediction of groundwater water quality after seepage through the filling body is as follows:
[0038]According to the position of the filling body 1, a monitoring roadway 2 arranged along the direction of the filling body is excavated at a distance a of 10m between the up...

A method for dynamic monitoring and prediction of filling body water quality, the steps of which include: excavating and monitoring tunnels; drilling holes with different angles in the tunnels; making and installing seepage water collection devices; Sampling to detect the content of toxic and harmful substances P x The pH value of seepage water is compared with the national standard value to judge whether the water quality meets the environmental protection requirements and realize the dynamic monitoring of water quality; if a certain number of tests do not meet the standard requirements, the test will be stopped, and the P in the seepage water obtained x and the data of seepage water pH value, seepage height h and seepage time t are regressed to get P x And the relationship between the pH value and h, t, using the relationship to predict whether the seepage water quality meets the standard requirements after a certain period of time. The method has a large detection range, the filling body seepage water is separated from the rock mass seepage water, and the detection result is accurate and reliable; monitoring time and labor costs can be saved through prediction.
Description
technical field [0001] The invention relates to groundwater quality safety monitoring, in particular to a water quality dynamic monitoring and prediction method after groundwater seepage in a filling body. Background technique [0002] With the introduction of the concept of sustainable development and the country's emphasis on safety and environmental protection, the use of filling and filling mining methods to achieve safe mining has become an important means for mines to solve environmental problems. Using the filling mining method to mine ore can maximize the use of mine tailing waste materials, control ground pressure and reduce the pressure of tailings ponds, and protect the environment well. However, the tailings of the filling body used in filling mining contain pollutants such as flotation agents and heavy metals. When it is filled underground, the water quality of the groundwater will change after seepage in the filling body, resulting in toxic and harmful substanc...
