An additive manufacturing process includes pressurizing and heating a slurry, flowing the pressurized heated slurry through a nozzle, and depositing the slurry in a predetermined pattern.

Emulsion explosives with gas bubbles that are resistant to in-borehole migration or coalescence are disclosed herein. Such emulsions can be sensitized by mechanically-introducing gas bubbles into the emulsion. Resistance to gas bubble migration and coalescence can be achieved by homogenization, without the need for bubble stabilization agents.

A truck for loading emulsion explosive in field with intrinsic safety, with its key improvement being a static emulsification device and a static sensitizing device to perform emulsification and sensitization, wherein, an outlet of the static emulsification device is connected with a transporting hose, a terminal end of a sensitizer storage transporting system is connected to a starting end of the transporting hose, and the static sensitizing device is arranged at a terminal end of the transporting hose. Its advantages include the transporting of emulsion explosive product is avoided, thereby reducing safety risk; on the other hand, the emulsification device and sensitizing device utilized by this truck both have static structure, so that there exists no shear or mechanical friction during the emulsification and sensitizing process, thereby reducing sensitivity, preventing explosion form happening in the production process, and ensuring production safety.

Controllers and methods of bulk explosive loading systems are disclosed. A controller of a bulk explosive loading system includes a communication interface configured to communicate with a human-machine interface (HMI). The HMI is configured to execute a software program configured to enable the HMI to receive user inputs from a user. The controller also includes control outputs to output control signals to electrically controllable components. The controller further includes sensor inputs configured to receive sensor signals from sensors configured to monitor the bulk explosive loading system. The controller also includes a processor configured to process recipe information received from the HMI, generate the control signals based on the recipe information to control the electrically controllable components to blend the mixture, process the sensor signals received during blending of the mixture, and transmit blending information to the HMI device. The blending information includes information regarding the blending of the mixture.
