Abstract

The invention discloses a bored grouting slurry spatial diffusion range and path description method, and relates to the technical field of a coal mining area bored grouting slurry diffusion range monitoring method. The method concretely comprises the following steps that a micro-earthquake monitoring system is constructed around a bored grouting area by utilizing an underground tunnel; artificial grouting is performed on a target aquifer through boring, and a micro-earthquake event is induced; grouting pressure, slurry concentration and slurry composition are adjusted, and the micro-earthquake event spatial distribution situation formed by slurry diffusion of different stages is observed; and the law of micro-earthquake event spatial distribution is analyzed, and full-space, real-time and continuous description of the slurry diffusion range, path and process is performed. With application of the method, the grouting slurry diffusion range, path and process can be accurately determined, and working area aquifer water storage structures and underground water flow field characteristics and other information can be provided so that the basis can be provided for grouting project optimization, grouting effect evaluation, rapid treatment of the water inrush accident and water resource protection.

Description

technical field [0001] The invention relates to the technical field of methods for monitoring the diffusion range of drilling grouting slurry in coal mine operation areas, and in particular to a method for describing the spatial diffusion range and path of drilling grouting slurry. Background technique [0002] The description of the diffusion range of drilling grouting grout is an important technology to prevent and avoid severe water inrush accidents in coal mines and ensure rapid grouting control of water inrush. Conventional techniques include geophysical prospecting, drilling, tracer tests, connectivity tests 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 of the above technologies can realize the f...
