연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The present invention is directed to a mobile platform for the delivery of bulk explosives to a blast hole. One embodiment of the platform provides the ability to obtain weight information relating to the contents of a tank that is associated with the platform and that, in operation, contains either the bulk explosive or a constituent of the explosive. The platform comprises a vehicle with a frame, a tank, a load cell structure for connecting the frame and the tank and providing weight data relating to the contents of the tank, and a suspension system that prevents relative movement of the frame and the tank that could compromise the load cell structure. Another embodiment of the platform provides a tank for holding an explosive composition and a rotary shaft that supports a mixing blade that mixes the explosive composition within the tank. The platform further comprises bearing structure for supporting the rotary shaft that is located to deter any of the explosive composition from entering the bearing. A further embodiment of the platform comprises a conduit structure for discharging a bulk explosive into a blast hole that includes a substantially rigid tube with an outlet port for discharging a bulk explosive into the blast hole. The tube is adapted to rotate about a vertical axis such that the outlet port can be moved towards and away from the vehicle along an arc of less than 180°. In one embodiment, the outlet port can be positioned substantially adjacent to an operator's station to allow an operator to readily view the loading of the explosive into the blast hole.
