Problems solved by technology

[0003] The existing installation method of the microseismic sensor in the deep borehole solves the problem of coupling and recovery between the sensor and the surrounding rock to a certain extent, but there are still problems of poor contact with the surrounding rock, difficulty in rapid recovery and low recovery rate
For example, the patent "ZL201811005295.6, A Microseismic Sensor Fixing and Recovering Device Suitable for Different Apertures" discloses a microseismic sensor installation device, which is suitable for the installation requirements of different diameters of drilling, and can improve the signal Transfer quality and effectively prevent rust, but the device is cumbersome when recycling the sensor, and the recycling rate of the sensor is low
Another example is the patent "ZL200610069883.7, Installation method of deep hole microseismic monitoring sensor in coal mine", which discloses a deep hole microseismic sensor installation method, which can realize that the microseismic sensor is firmly blocked in the borehole, but the sensor cannot be recovered, which increases the monitoring cost

Description

technical field [0001] The invention belongs to the technical field of microseismic sensors, and in particular relates to a device and method for rapid installation and recovery of a microseismic sensor in a downhole hole. Background technique [0002] With the development of deep underground engineering, the mining depth of coal mines and metal mines exceeds one kilometer, and the stability of the roadway is seriously threatened in the process of deep mining. Microseismic technology has been widely used in underground engineering construction to monitor the stability of roadway surrounding rock. Microseismic monitoring is a three-dimensional real-time monitoring technology, which provides guidance for engineering construction by transmitting the signal received by the sensor into the host to conduct rupture location and rupture energy research. A very important aspect that affects the effect of microseismic monitoring is the number of sensors and the coupling quality. Aft...
