Description

technical field [0001] The invention belongs to the technical field of anti-collapse hole protection, and in particular relates to a microseismic monitoring sensor anti-collapse hole protection device, a control method, a medium and an application. Background technique [0002] At present, microseismic monitoring technology is a technology that records the shock waves released by rock rupture through multiple sensors arranged in the rock mass area, and evaluates and studies the spatiotemporal evolution law of surrounding rock damage, damage mechanism, and the strength of microcracks. Microseismic monitoring technology is widely used in mining, petroleum, hydropower and other engineering fields. During microseismic monitoring, the installation quality of on-site sensors is the prerequisite for the smooth development of microseismic monitoring work. In order to ensure that the microseismic monitoring equipment can continuously and accurately collect on-site data, the sensors a...

Problems solved by technology

[0003] The existing microseismic monitoring technology basically performs grouting treatment when installing the sensor in the rock mass, so that it is permanently retained in the rock mass for monitoring and cannot be recovered and repaired, or it is directly placed in the rock mass for installation and installation The hole is fixed in the hole, and the anti-collapse hole protection device is simple, and even the anti-collapse hole protection cannot be carried out. In addition, some sensors are directly installed on the air surface near the working surface for monitoring. Although this method can recover the sensor, its The effect is not as good as the installation in the rock, and the effect is more obvious. Generally speaking, there is no suitable device that can adapt to the surrounding rock conditions of different stress levels and completely recover the sensor.

[0004] Through the above analysis, the problems and defects of the existing technology are: the existing microseismic monitoring technology basically performs grouting treatment when installing the sensor in the rock body, so that it is permanently retained in the rock body for monitoring and cannot be carried out. Recycling and repairing, or directly fixing it in the installation hole of the rock mass, the anti-collapse hole protection device is simple, and even the anti-collapse hole protection cannot be carried out. In addition, some sensors are directly installed on the air surface near the working surface Although this method can be used for sensor recovery, its effect is not as obvious as that of installation in rocks. Generally speaking, there is currently no suitable device that can fully recover sensors that can adapt to different stress levels of surrounding rock conditions.

[0005] The difficulty in solving the above problems and defects is that different projects have different rock stress conditions and geological environments, and after excavation and unloading, the deformation degree and deformation rate of the surrounding rock cannot be accurately controlled, resulting in complex and changeable engineering environments. The use, protection and recycling of microseismic monitoring sensors have brought great difficulties, and it is easy to cause damage and burial of sensors, because sensors are expensive, and the loss of sensors means property loss. The sensor protection device integrated with recovery can only be monitored under the condition of average monitoring effect sometimes, so there is an urgent need for the emergence of a sensor protection device suitable for various degrees of hole collapse
