The invention discloses a method for installing an
acoustic emission sensor on a mine, and belongs to the technical field of
acoustic emission monitoring of a mine
coal-rock
mass. The method for installing the
acoustic emission sensor on the mine comprises the following steps of (1) carrying out drilling on a mine
coal-rock stratum according to the requirement of the design and construction; (2) conveying the sensor to the bottom of a hole through a conveying
pipe to enable the acoustic emission sensor and the hole wall of the drilled hole to be in tight
coupling contact, wherein the acoustic emission sensor comprises a
signal line, an outer shell, an acoustic emission
signal receiver and clamping jaws; (3) pulling the conveying
pipe out, enabling the clamping jaws of the acoustic emission sensor to clamp the hole wall of the drilled hole so that the acoustic emission sensor cannot slide off, and arranging a
signal circuit of the acoustic emission sensor; (4) using mining hole sealing agents to block the hole opening of the drilled hole to isolate interference
noise of the outside world. According to the method for installing the acoustic emission sensor on the mine, due to the fact that the acoustic emission sensor is embedded into the rock
mass in a drilling mode, interference caused by the
noise of the outside world on real-time monitoring is avoided, and monitoring precision is improved; due to the fact that the clamping jaws are fixedly arranged in the drilled hole, the acoustic emission sensor and the rock
mass of the mine are tightly coupled, and the problems that grouting is tedious and whether grouting is in place or not cannot be easily judged are effectively solved.
