Abstract

a presente invenção refere-se a métodos e sistemas para determinar uma mudança em condição de um parafuso de rocha. alguns métodos podem compreender, em um primeiro ponto no tempo, propagar ondas ultrassônicas de cisalhamento e longitudinais ao longo do parafuso de rocha para medir um primeiro tempo de voo para cada uma das ondas de cisalhamento e longitudinais, e em um segundo ponto no tempo após o primeiro ponto no tempo, propagar ondas ultrassônicas de cisalhamento e longitudinais ao longo do parafuso de rocha para medir um segundo tempo de voo para cada uma das ondas de cisalhamento e longitudinais. um valor de correção de temperatura é também determinado. os primeiro e segundo tempos de voo e o valor de correção de temperatura são utilizados para calcular uma mudança relativa corrigida em temperatura entre os primeiro e segundo tempos de voo para cada uma das ondas ultrassônicas de cisalhamento e longitudinais nos primeiro e segundo pontos no tempo. utilizando as mudanças relativas corrigidas em temperatura dos primeiro e segundo tempos de voo para determinar a mudança em condição do parafuso de rocha.
