CN101526009 Wall rock destabilization acousto-optic-electric integrated monitoring system and monitoring method thereof.

The invention discloses a wall rock destabilization acousto-optic-electric integrated monitoring system and a monitoring method thereof, wherein the monitoring system comprises an optical drilling sighting apparatus fractionally monitoring the wall rock damage condition of the inner all of the same drilling hole, an acoustic emission device and a drilling hole stress meter, and a control receiver connected with the drilling hole stress meter, the acoustic emission device and the optical drilling sighting apparatus. The monitoring method comprises the following steps: firstly, drilling on the edge of a laneway; secondly, monitoring: monitoring the inner wall of the drilling hole by the optical drilling sighting apparatus, and then further monitoring the inner wall of the drilling hole by the acoustic emission device, secondarily monitoring the inner wall of the drilling hole by the optical drilling sighting apparatus, at last monitoring the wall rock stress of the inner wall of the drilling wall of the drilling hole stress meter; thirdly, collecting all monitoring results, and differentiating and analyzing the wall rock damage destabilization condition. The invention has reasonable design, simple use and operation, and accurate monitoring result, and can effectively solve the practical problems of poor accuracy, distorted data, failure monitoring under some special environment, and the like caused by the prior single monitoring method.
