Problems solved by technology

Due to the low detection accuracy and intelligence of the drilling plugging leak detection device, the development of cracks around the drilling cannot be interpreted; and due to the existence of hydrostatic pressure, it is not suitable for the depth detection of crack damage in the floor
Coupling fluid is required for ultrasonic detection, and the downhole roof drilling is an upward hole and the floor drilling is sometimes a dry hole (simple downhole drilling without cement slurry, water and other coupling fluids), which loses the conditions for water to be used as a coupling fluid. Makes the current ultrasonic technology impossible for construction measurement

Abstract

The invention relates to an ultrasonic detecting device and system for downhole rock fracture drilling. The device comprises two detecting parts, a connecting part, an air conveying pipeline and a water conveying pipeline. Each detecting part comprises a shell, two air bags disposed on the outer side of the shell and an ultrasonic transducer located between the two air bags, wherein the peripheral lateral wall, between the two air bags, of the shell is provided with water leaking holes, and the peripheral lateral wall, corresponding to each air bag, is provided with air holes communicated with the corresponding air bag. The two detecting parts are connected through the connecting part. One end of the air conveying pipeline is respectively connected with the air holes of the two detecting parts, and the other end thereof forms an external air conveying connector. One end of the water conveying pipeline is respectively connected with the water leaking holes of the two detecting parts, and the other end of the water conveying pipe forms an external water conveying connector. The ultrasonic detecting device has the advantages that the device integrates air pressure detecting, coupling liquid leakage amount detecting and ultrasonic detecting, rock fracture growth conditions can be explained by jointly using ultrasonic and leakage amount, and fracture growth detecting precision is increased.

Description

technical field [0001] The invention relates to the geological field, in particular to an ultrasonic detection device and system for underground rock mass fissure drilling. Background technique [0002] At present, with the continuous deepening of coal seam mining, the geological structure and hydrogeology are becoming more and more complex, the depth of mine pressure damage to the floor is increasing, and the fully mechanized caving mining of extremely thick coal seams and long-span working faces makes the development mechanism of roof cracks increasingly complex. Because the water pressure of the main water-filled aquifer in the mining coal seam increases significantly, the probability of water inrush on the roof and floor increases significantly. At present, the main method for detecting the development height of the roof water-conducting fracture zone and the depth of floor fracture damage is drilling plugging and water injection, and the development of rock mass fractur...
