Abstract

"CáPSULA DE CARTUCHO E CARTUCHO PARA BURACOS DE MINA E MéTODO DE USO". é descrito um cartucho (10c) que compreende um corpo (12) definindo um volume para conter um material energético. O corpo (12) possui uma primeira extremidade (16) localizada adjacente à ponta (48) do buraco (46) formado em um material duro (47), e uma segunda extremidade (18) direcionada em direção à garganta (50) do buraco (46). A extremidade (18) é afunilada para formar uma ponta ou membro em forma de cunha. O material de represamento (52) é colocado no buraco (46) para um nível abaixo da face livre (54) de material duro (47) e mecanicamente mantido no lugar por uma barra de represamento (56). Quando o material energético é detonado, a pressão de gás força o cartucho (10c) em direção à garganta (50). A medida que isso ocorre, a ponta atua para aumentar a força compressiva radial sobre o material de represamento (52) na região anular entre a extremidade (18) e a porção adjacente do buraco (46). Isso aumenta o efeito de vedação do material de represamento (52) e mantém constante o volume no buraco (46) dentro do qual opera o gás.
