Problems solved by technology
In the traditional device, there are two external systems, the water injection operation platform and the plugging operation platform. There are relatively many operators, and there are 2 pipes corresponding to the drilled holes. During the propelling process, mutual entanglement is prone to occur, and at least it will cause the device to be blocked. If it is blocked or the observation process is unstable, it is easy to break the gas supply pipeline, causing the equipment to fail to work normally. Moreover, the traditional device is a test unit, and the detection efficiency is low. How to realize multi-segment measurement, reduce the number of pipelines in the borehole, and can Effectively control the water pressure, the existing technology fails to solve the above problems at the same time

The invention discloses a segmental observation method for a mine roof and floor mining damage zone, which belongs to the technical field of rock mass damage range measurement. The observation system used includes test probes, drilling rigs, drill pipes, and control consoles. The test probe includes a front occluder, a rear occluder, a converter and a connecting tube. The occluder includes a leaking tube, joints connected at both ends of the leaking tube and a rubber bag. The rubber bag wraps around the leaking tube and is connected to the leaking tube A blocking cavity is formed between them, and the external water source is injected into the blocking cavity to inflate the rubber bag, forming a water injection cavity with the drilled hole. The test device can use the same external water source to complete the plugging process and the test process, and realize variable control of high and low water pressures to ensure that the two work under their respective required pressures, eliminate the entanglement of drill pipes and hoses, and reduce operations. Steps and number of workers, improve the efficiency of advancing measurement.
Description
technical field [0001] The invention belongs to the technical field of rock mass damage range measurement, and in particular relates to a segmented observation method for mine roof and floor mining damage zones. Background technique [0002] The measurement of the range and permeability of the rock mass mining fracture zone is the basic parameter for studying the failure characteristics of the rock mass. It is of great significance for further exploring the relationship between it and the movement law and stress field of the rock mass. Variable electromagnetic method, microseismic detection and pressure water test method. Among them, the pressure water test method is the most reliable. The traditional device "double-ended side leakage device" is used to conduct water injection and discharge tests to determine the development height or depth of the rock formation affected by mining. In the traditional device, there are two external systems, the water injection operation plat...
