Embodiment Construction
[0026] Such as figure 1 As shown, the sources of water inrush in the underground rock mass include surface water source 1, roof aquifer water source 3 and floor aquifer water source 5, and inrush water channel 2 is formed under the influence of underground space 4 formed by mining.
[0027] This embodiment provides a three-dimensional space identification and positioning method for water inrush channels in underground rock mass, including the following steps:
[0028] Step 1. Establish the hydrochemical characteristics database of each water source in the rock mass according to the previous geological exploration, collect the water in the underground water inrush and analyze its hydrochemical characteristics, and use the method of combining principal component analysis and multivariate statistical analysis to determine The location of the water inrush source at the underground water inrush. Borehole 9 is drilled out to the direction of water inrush source in underground space...

The present invention provides a three dimensional space identifying and positioning method of a water inrush channel in an underground rock mass. The method comprises the following steps of 1 determining the position of a water inrush source, and drilling a hole towards the direction of the water inrush source via the underground rock mass and in the underground space; 2 putting a plurality of miniature signal emission balls in the water inrush source via the drilled hole, wherein the positioning signal emitters are arranged in the miniature signal emission balls; 3 arranging a signal reception probe towards the position of the water inrush source via the drilled hole, wherein the signal reception probe is in signal connection with a signal analyzer, and the signal analyzer receives the spatial position information of each miniature signal emission ball via the signal reception probe; 4 determining the spatial position distribution of the water inrush channels in the underground rock mass according to the spatial positions of all miniature signal emission balls, and determining a primary water inrush channel and a secondary water inrush channel in the underground rock mass according to the aggregation degree of the miniature signal emission balls. The beneficial effect of the present invention is that the space positioning of the water inrush channels in the underground rock mass can be realized.
Description
technical field [0001] The invention relates to the technical field of underground rock mass water inrush detection, in particular to a three-dimensional space identification and positioning method for water inrush channels in underground rock mass. Background technique [0002] With the rapid development of my country's economy, the demand for subway tunnels, underground space construction and underground resource mining has increased. Underground rock mass engineering in complex geological environment, especially deep rock mass engineering, faces problems such as high pressure of confined water, large amount of inrush water, poor identification of water inrush channels, etc., resulting in inaccurate positioning of grouting plugging and poor plugging effect , it is difficult to achieve an effective plugging effect, resulting in serious economic losses. [0003] In the prior art, it is difficult for transient electromagnetic technology to generate high-precision exploration...
