Description
(54) СПОСОБ АКУСТИЧЕСКОЙ ДЕФЕКТОСКОПИИ ГОРНОГО МАССИВА, ОКРУЖАЮЩЕГО ШАХТНЫЕ СТВОЛЫ(54) METHOD FOR ACOUSTIC DEFECTATION OF MINING MASSIF, ENVIRONING MINE STEMES

Изобретение относитс к технике определени свойств горного массива на месте разработки , в частности к способу акустической дефектоскопии горного массива, окружающего шахтные стволы.The invention relates to a technique for determining the properties of a rock mass at a development site, in particular, to a method for acoustic inspection of a rock mass surrounding a shaft.
Известен способ акустической дефектоскопии горного массива, окружающего шахтные стволы, основанный на раздельном излучении и регистрации прошедших через горный массив упругих волн. Однако указанный способ вл етс весьма трудоемким.There is a method of acoustic flaw detection of the mountain massif surrounding the shafts, based on separate radiation and registration of elastic waves transmitted through the rock mass. However, this method is very time consuming.
Цель изобретени - снижение трудоемкости измерительных работ. Это достигаетс тем, что обсадные колонны замораживающих скважин возбуждают поочередно ультразвуковым преобразователем и по распределению интенсивности упругих волн на внутренней поверхности тюбинговой крени суд т о наличий И геометрической конфигурации нарушений .The purpose of the invention is to reduce the complexity of the measurement work. This is achieved by the fact that the casing strings of the freezing wells excite one by one with an ultrasonic transducer, and according to the distribution of the intensity of elastic waves on the inner surface of the tubing roll, the difference And the geometrical configuration of disturbances is judged.
