Turli mustahkamlikdagi tog’ jinslari massivida portlovchi moddalarning sh ’ajinali zarvadlarini kumulyativ effekt orqali port]adsh ta'sirining fizikaviy modellashdrish metodikasi ishlab chiqilgan. Aniqlangan o'zgarish qommiyatlari: kimndyativ vopilishda konus qoplamasi balandligidan vopilish tezligi, fokus masofasidan qattiq oraliq qatlamlargacha bo'lgan kimndyativ voronkaning vopilish burchagi, kimndyativ qoplama tepasi va mustahkam qatlandar aro buzdish chuqurligidan fokus masofaga bog'lik bo Igan kimndyativ oqim tezligi.
Tayanch iboralar: fizik modellashdrish metodikasi, portlashning ta ’siri, s h ’ajinadagi zarvad, portlovchi modda, kimndyativ samaradorlik, kon massivi, har-xil qattiqlikdagi jinslar, kimndyativ о 'yiqning vopolishi, konusli qoplama balandligi, vopolish burchagi, focus masofa,buzdish chuqurligi, qovushqoqlik qommiyati, berk tizim tenglamasi, tog’ jinslarini maydalashda unumdorlikni oshirish, burg ’ulash portlatish ishlari parametrlari, noqulay gidrogeologik sharoit.
A method o f physical modeling o f explosion effects o f the downhole explosive charges with the cumulative effect in massif o f rocks o f different strength was developed. Determined the laws o f change: the collapse rate o f charge hollow from the conical lining height, collapse angle o f cumulative funnel from the focal distance to the good streaks, cumulative je t speed on the angle o f the top o f the cumulative lining and the destruction depth o f good streaks, depending on the focal distance.
Key words: method o f physical modeling, explosion effects, downhole charge, explosives, cumulative effect, rocks o f different strength massif, collapse rate o f charge hollow, conical lining height, collapse angle, focal distance, destruction depth, theory o f elasticity, closed system o f equations, crushing intensification o f the rock massif, parameters o f drilling and blasting operations, complex hydrogeological conditions.
