Embodiment Construction
[0029] In order to clearly illustrate the technical characteristics of this patent, the following describes this patent in detail through specific implementation methods and in conjunction with the accompanying drawings.
[0030] The present invention as Figure 1-4 shown, proceed as follows:
[0031] S1. Installation and automatic monitoring of large-scale microseismic monitoring system;
[0032] S1.1. According to the geological data of the coal mine rock mass and the needs of engineering construction, the monitoring range of the coal mine rock mass is delineated, and the coal mine rock mass within the monitoring range is divided into different grids according to the elevation and the horizontal and vertical spacing;
[0033] S1.2. Install the probe through the drill hole in the middle of the divided grid, and install the rock bridge microseismic automatic monitoring probe at the port above the probe; The microseismic automatic monitoring probe collects and remotely transm...

The invention discloses an intelligent positioning and feature recognition method for a rock bridge in a coal mine rock mass, and relates to the field of coal mine rock mass monitoring. According to the method, the engineering problem that the position and feature information of the rock bridge cannot be accurately judged and positioned at present can be solved, the defects of conventional design can be overcome, the stability of the rock bridge can be analyzed more reasonably and accurately, and beneficial guidance can be provided for the design, monitoring and construction process of coal mine rock mass. The method comprises the following steps: S1, mounting and automatically monitoring a large-scale micro-seismic monitoring system; s2, automatically processing micro-seismic monitoring data and preliminarily identifying the position of a rock bridge; and S3, accurate positioning and feature recognition of the rock bridge. Through accurate positioning analysis of the rock bridge, favorable guidance can be provided for design and construction monitoring, and the stability and safety of the coal mine rock mass are ensured.
Description
technical field [0001] The invention relates to the field of coal mine rock mass monitoring, in particular to an intelligent positioning and feature recognition microseismic equipment system for rock bridges in coal mine rock mass. Background technique [0002] As a typical mine geological disaster, rock mass instability in coal mines has caused huge economic losses and casualties around the world, so it has attracted extensive research. However, due to the complexity of rock mass instability mechanism, the evolution of rock mass instability is still not fully understood. However, due to its huge potential energy, large-scale rock mass instability often forms a high-speed, long-distance, and "collapse→slip→flow" chain geological disaster after breaking away from the parent rock, often causing devastating damage and heavy casualties. The instability of coal mine rock mass involves different geological environmental conditions and geological structures, and has different indu...
