Maqolada buzilgan kon jinsining fizik xususiyatlarini tiklanishga qaratilgan ilmiy izlanishlar keltirilgan. Buzilgankon jinslarining ellastik modulining xarakterli o'zgarishi undan o'tadigan to’lqin tezligiga bog'liq bo'lib olingan natijalarko'rsatadiki, buzilgan kon jinsida to'lqin tezligining buzilmagan kon jinsi orqali o'tadigan to'lqin tezligining nisbatinisaqlanish koeffitsienti deyilganda to'lqin tezligining boshlang'ich kon jinsidan o'tish tezligi oshadi.

Tayanch iboralar: buzilgan va buzilmagan kon jinsi, yoriq tarmog'i, elastic moduli, gamma-gamma kartonaj, konjinslarining mustahkamligi kamaygan chegarasi, bo'ylama va ko'ndalang to'lqin, Puasson koeffitsienti, kvaziplastikyemirilish, plastik-ellastik tavsif seysmoakustik usul, kon jinsining boshlang'ich zichligi, saqlanish koejfitsienti, massivningfizik hususiyati, ko'ndalang to'lqinnig boshlang'ich tezligi, kon jinsining egiluvchanlikka qarshiligi.

The article presents the results o f a study on the restoration ofphysical properties o f an array o f disturbed rocks. Acharacteristic feature o f the modulus o f elasticity o f disturbed rocks is its dependence on the initial velocity o f the wave.The analysis o f the obtained data shows that i f we take the ratio o f the speed o f the wave in the zone o f disturbances tothe wave velocity in the original rock as a factor o f conservation o f rocks, then, depending on the velocity o f the wave inthe original rock, the conservation factor Changes in accordance with the dependence, the higher the initial strength o fthe rocks, their fragility, the greater the decrease, the higher the loss o f the preservation o f the rocks.

Key words: dislocated and undisturbed rocks, cracking pattern, elasticity modulus, gamma-gamma logging, zone o fweakness o f rocks, transverse and longitudinal waves, Poisson ratio, quasiplastic demolition, elastic plastic characteristic,seismic-acoustic method, original density o f rocks, safety factor, physical properties o f an array, initial velocity o flongitudinal wave, resistance to rocks shear.
