Abstract
(EN)
A blasthole guard may include a conduit and a cap. The conduit is sized and shaped to allow a hose to pass through. The cap comprises a funnel that narrows to an open end of the conduit. A slot continuously extends from the conduit through the cap such that the slot forms an opening that extends along an entire length of the device.
(FR)
Une protection de trou de mine peut comprendre un conduit et un capuchon. Le conduit est dimensionné et formé pour permettre à un tuyau de passer à travers celui-ci. Le capuchon comprend un entonnoir qui se rétrécit vers une extrémité ouverte du conduit. Une fente s'étend en continu à partir du conduit à travers le capuchon de telle sorte que la fente forme une ouverture qui s'étend sur toute la longueur du dispositif.
