Abstract

The invention, which relates to the technical field of the underground water flow field measurement method at the coal mine operating area, discloses an underground water flow field description method based on manual filling. The method comprises the following steps: determining a filling drilling position and constructing an underground micro-seismic monitoring system by using an underground tunnel; carrying out filling drilling construction and carrying out manual filling on a main aquifer of a target mine lot by the filling hole to generate micro-seismic events; carrying out full-space real-time continuous monitoring on all micro-seismic events by stages at a monitoring area by the underground micro-seismic monitoring system during the filling process; and according to the micro-seismic events, describing an underground water flow field. With the method, information containing the underwater strong runoff zone location, aquifer water-storage structural morphology, and serous fluid diffusion range and the like can be determined accurately; and a technical basis can be provided for preventing and avoiding occurrence of major water inrush accidents of coal mine and rapid treatment of the water inrush accidents as well as water resource protection.

Description

technical field [0001] The invention relates to the technical field of methods for measuring groundwater flow fields in coal mine operation areas, in particular to a method for describing groundwater flow fields based on artificial liquid injection. Background technique [0002] The characteristics of groundwater flow field and the description of the diffusion range of grouting slurry are an important technology to prevent and avoid severe water inrush accidents in coal mines and ensure rapid grouting treatment of water inrush. Conventional technologies include geophysical prospecting, drilling, water injection (grouting) test, tracer test, connection test and other technologies. Geophysical prospecting technology is greatly affected by surface terrain conditions and underground roadway conditions; drilling costs are high and the control range is small; various hydrogeological tests require a lot of auxiliary conditions due to large projects and complex operations, and none ...
