Maqolada dala sharoitida kon jinslarining mustahkamlik, elastiklik va deformatsion xususiyatlarini aniqlash uslubi keltirilgan. Kon jinslarining mustahkamlik, elastiklik va deformatsion xususiyatlarini ko'p karrali portlatish orqali kamayishini aniqlovchi kompleks uslubi ishlab chiqildi va shu asosida mikrodarzliklarning umumiy hajmi katta mak-rodarzliklar ajralmagan va ularning ko'payishi boshlanmagan holda kon jinslarining maydalanish mezonlari aniqlangan.
Tayanch iboralar: izlanish uslubi, mustahkamlik xususiyatining kamayishi, kon jinslarining elastiklik va deformatsion xususiyati, ko'p karrali portlatish zuriqmasi, kon massivining maydalanishi, boshlanish bosqichi, mikrodarzliklar xajmi, katta makrodarzliklar, texnik- iqtisodiy ko'rsatkichlar, maydalovchi-boyituvchi uskunalar, davriy-o'zluksiz texnologiya, portlatilgan kon massasi, rudani transport qilish, granulometrik tarkibi, kon jinsi mustahkamligini kamayishi.
In the article the research technique of decrease of strength, elastic and deformation properties of rocks in polygon conditions is considered. A complex method for studying the reduction in strength, elastic and deformation properties of rocks with multiple explosive loads was developed, on the basis of which criteria for crushing rocks were determined, which were instrumental in the initial stage, when large macro-cracks had not yet emerged from the total volume of mi-cro-cracks and their growth had not yet begun.
Key words: research technique, decrease in strength properties, elastic and deformation characteristics of rocks, multiple explosive loads, crushing of the mountain mass, initial stage, micro-cracks volume, large macro-cracks, tech-nical and economic indicators, crushing and processing equipment, cyclic-flow technology, blown up rock mass, ore transportation, granulometric composition, reduction of rock strength.
