Abstract: The present invention describes a mechanical coupling microseismic monitoring system, which includes at least one microseismic sensor, push rods that are arranged at both ends of the microseismic sensor through a first connection mechanism to send the microseismic sensor into the monitoring hole, introduction mechanisms that are mounted on the push rods for introducing the microseismic sensor into the monitoring hole, and one microseismic monitoring computer that receives signals from the microseismic sensor; the microseismic sensor is a recoverable microseismic sensor; the first connection mechanism is a connection mechanism that can make the push rod swing relative to the microseismic sensor; the introduction mechanism is a three-roller introduction mechanism. The present invention meets the requirement of microseismic monitoring for different parts of deep monitoring hole using multiple microseismic sensors.

Abstract: The invention discloses a monitoring system for deformations and destructions of a gas storage, including an acoustic emission sensor installed in a borehole of a monitored rock mass and a ground workstation. The acoustic emission sensor includes an acoustic emission probe and a probe installation mechanism for installing the acoustic emission probe and a transmission mechanism for transmitting the probe installation mechanism. The probe installation mechanism includes a shell, a probe sleeve and two sets of pistons hydro-cylinder components. The present invention realizes the control of the moving direction of the shell and the probe sleeve by the piston hydro-cylinder component and the hydraulic pump, thus solving the problem of effective installation and coupling of the acoustic emission probe, ensuring the effective coupling between the acoustic emission probe and the wall of the borehole.

Abstract: The present invention discloses a rock mechanics experiment system for simulating deep-underground environment, including a triaxial chamber consisting of a chamber cavity and a test pedestal, a stress field building module, a high pressure seepage field building module, a high temperature field building and a seepage medium permeating control measurement module arranged in the triaxial chamber, a lifting module used for installing and disassembling of the chamber cavity, and computer module used for controlling the operation of system and calculating and outputting the test data. The lifting module includes a door-shaped support frame, a cylinder piston device vertically mounted on the door-shaped support frame beam, a coupling device and a safety suspension device. The coupling device includes an oil hydraulic rod with the upper end fixedly coupled with the piston, a safety disk fixedly coupled with the lower end of the hydraulic rod, and two symmetrically disposed coupling assemblies.
