Abstract

The invention discloses a surrounding rock anchor bolt stress wave positioning monitoring system. The surrounding rock anchor bolt stress wave positioning monitoring system comprises an anchor bolt monitoring matrix which is fixed in an underground tunnel or a mined-out area and formed by a plurality of anchor bolts; the tail end of every anchor bolt is provided with a ground pressure sensor, a wireless transmitter and a battery module; the surrounding rock anchor bolt stress wave positioning monitoring system also comprises an underground wireless receiver and a repeater; the surrounding rock anchor bolt stress wave positioning monitoring system also comprises an aboveground repeater, an early warning software computer, a server and a client computer. According to the surrounding rock anchor bolt stress wave positioning monitoring system, the real-time dynamic monitoring can be performed on the surrounding rock stress and transient stress waves, the high-frequency collection on the ground pressure information is implemented, the comprehensive analysis is performed on the surrounding rock stress and the instantaneous stress waves, the ground pressure monitoring and early warning of the three-dimensional space are performed, the cost is low, the installation is convenient, the applicability is wide, and the operation is simple.

Description

technical field [0001] The invention relates to a surrounding rock stress monitoring technology, in particular to a surrounding rock bolt stress wave positioning monitoring system. Background technique [0002] With the deepening of large-scale mine mining and the expansion of mining area and volume, mine ground pressure disasters have gradually become a common disaster type in mine production activities. Especially in today's people-oriented information age, people's demand for monitoring and early warning of land pressure disasters in mines is more urgent. [0003] The traditional ground pressure measurement technology is based on various theories such as optics, mechanics, seismology, and electromagnetism. Many aspects, such as equipment and application, are quite mature. The application of the above-mentioned technologies is independent of each other, and each method has unique advantages and disadvantages. [0004] Advantages: The above-mentioned monitoring technologi...
