Abstract

"COMPOSIçãO TRANSMISSORA E MODERADORA DE CHOQUE EXPLOSIVO, CONCENTRADO PARA SER MISTURADO COM áGUA PARA USO NA COMPOSIçãO DE UM GEL TRANSMISSOR E MODERADOR DE CHOQUE EXPLOSIVO, E, PROCESSO PARA DINAMITAR ROCHA". Lajes (10) ou peças (17) de rocha são quebradas de grandes rochas ou de formações rochosas (11) com reduzido fraturamento das lajes ou peças de rocha quebradas pela perfuração de furos (13, 14, 15, 16) ao longo das desejadas linhas de quebra, colocando cordel detonante (20) nos furos, enchendo os furos com uma composição transmissora e moderadora de choque (21), e detonando o cordel detonante (20). A composição transmissora e moderadora de choque (21) é, de preferência, um gel com material absorvente de choque (22), como micro-esferas ou microbolhas de gás em suspensão nele. Aberturas na rocha também podem ser formadas pela perfuração de pelo menos um furo dentro da desejada abertura e pela perfuração de uma pluralidade ao longo da desejada periferia da abertura. Explosivos dentro de pelo menos um furo dentro da desejada abertura são detonados para quebrar a rocha dentro da abertura e o cordel detonante (20) nos furos ao longo da desejada periferia da desejada abertura cujos furos são cheios com uma composição transmissora e moderadora de choque (21) é detonado para quebrar a rocha para o interior da desejada periferia ao mesmo tempo que deixa estável a rocha externa à periferia."EXPLOSIVE SHOCK TRANSMITTER AND SHOCK COMPOSITION, CONCENTRATED TO BE MIXED WITH WATER FOR USE IN THE COMPOSITION OF AN EXPLOSIVE SHOCK TRANSMITTER AND SHOCK GEL, AND PROCESS TO DAMAGE ROCK". Slabs (10) or pieces of rock (17) are broken from large rocks or rock formations (11) with reduced fracturing of slabs or pieces of rock broken by drilling holes (13, 14, 15, 16) along the desired ones. break lines by placing detonating string (20) into the holes, filling the holes with a shock-moderating transmitter composition (21), and detonating the detonating string (20). The shock transmitting and moderating composition (21) is preferably a gel with shock absorbing material (22), such as microspheres or microbubbles of gas suspended therein. Openings in the rock may also be formed by drilling at least one hole within the desired opening and drilling a plurality along the desired periphery of the opening. Explosives within at least one hole within the desired aperture are detonated to break the rock within the aperture and the detonating string (20) into the holes along the desired periphery of the desired aperture whose holes are filled with a shock moderating and transmitting composition ( 21) is detonated to break the rock into the desired periphery while leaving the rock external to the periphery stable.
