Abstract: Within the technical field of detecting a mining-induced failure range of rock mass, and particularly relating to a graded-pressure drop type detection system and detection method of borehole cracks, a detection system is provided including a test probe, a drilling rig, a drill pipe and a control operation platform. The test probe includes a plugging device and a pressure conversion assembly. The pressure conversion assembly is connected with the plugging device at the rear end through a connected pipe and includes a first stage pressure converting device and a second stage pressure converting device. The detection system simplifies the existing operating system, avoids the problem of drill pipes winding in drill hole, realizes plugging process and detection process with the same external water source, and ensures that the plugging process and the observation process operate under respective predetermined pressures.

Abstract: A graded pressure drop type multi stage water injection device and method based on fracture observation. The device includes a test probe, a propulsion system and a control system. The test probe includes a plugging device, a pressure conversion assembly and a connected pipe. The rubber bag is wrapped around the outer end of the water leakage pipe, is fixed to both ends of the joints through a fastening iron ring and forms a blocked cavity with the water leakage pipe. The device integrates the plugging and detection system, and uses the same external water source to operate the plugging process and detection process under their respective pressures, thereby making pressure conversion more stable, solving the problem of winding the drill pipe and the hose in the propulsion process, realizing multi stage measurement in each propulsion and improving measurement efficiency.

Abstract: The present invention provides a dynamic set associative cache apparatus for a processor. When read access occurs, the apparatus first determines a valid/invalid bit of each cache block in a cache set to be accessed, and sets, according to the valid/invalid bit of each cache block, an enable/disable bit of a cache way in which the cache block is located; then, reads valid cache blocks, compares a tag section in a memory address with a tag block in each cache block that is read, and if there is a hit, reads data from a data block in a hit cache block according to an offset section of the memory address.
