Abstract: The present invention discloses a microseismic monitoring system, which includes at least a microseismic sensor, a push rod set at both ends of the microseismic sensor through the first connecting mechanism for sending the microseismic sensor into a monitoring hole, a guide mechanism installed on the push rod for guiding the microseismic sensor into the monitoring hole, and a microseismic monitoring computer connecting with the microseismic sensor signal. The microseismic sensor is reusable. The first connecting mechanism can make the push rod swing relative to the microseismic sensor. The guide mechanism is a three-roller guide mechanism. The present invention can satisfy the need of monitoring different locations in monitoring holes with large depths for multiple microseismic sensors, and solve problems of effective contact coupling between the microseismic sensors and monitoring holes, which improves the accuracy of microseismic monitoring and reduces the cost of a microseismic monitoring system.

Abstract: A rock damage mechanics test system for high temperature and high pressure deep earth environment includes an MTS triaxial test machine and a control system connected therewith. The MTS triaxial test machine is composed of a rigid frame, a high temperature and high pressure triaxial chamber, and a triaxial chamber base. The control system includes a workstation for data processing and a manual controller for controlling the workstation and a master controller. The system improves mounting and dismounting efficiency of an MTS triaxial force sensor, enhances reliability of lifting and solves the problem of aligning holes during the force sensor mounting process, thus improving the mounting efficiency.

Abstract: A triaxial high temperature and high pressure rock mechanics load test platform includes a base, a lifting seat, and an intermediate connecting seat arranged between the base and the lifting seat. A hydraulic assembly is arranged between the base and the intermediate connecting seat; the intermediate connecting seat is connected with the lifting seat by means of a group of connecting rods; the lifting seat is enclosed by a side wall and a base plate to form a receiving groove with an upward opening; and a limiting device is arranged on the side wall of the lifting seat for preventing an MTS triaxial force sensor from disengaging from a support disk.
