Abstract: An optimization method for a directional preparation technique and efficient use of semi-coke for blast furnace injection. Firstly, the volatile and the ash content of target semi-coke are preset, and then the volatile and the ash removal percentages of a raw coal are calculated; after ash removal, several sets of dry distillation carbonization temperatures and carbonization times are obtained according to the volatile removal percentage, and the relationships between a combustion rate, abrasiveness, explosiveness and jet flow property and the carbonization temperature are respectively established to obtain the optimal actual carbonization temperature; and semi-coke for blast furnace injection is obtained at an actual carbonization temperature.

Abstract: Provided is a method for bedding precise pressurized water injection based on coal seam interval hydraulic gradient calculation, including: setting pressure measurement boreholes on both sides of a water injection borehole with the water injection borehole as the center, and installing monitoring devices to measure internal stress of the pressure measurement boreholes in real time; during the coal seam water injection process, real-time pressure changes are obtained to determine the along-the-path dynamic damage of the pressurized water; according to the pressure difference changes within different water injection radius ranges and the pressure change nodes of the pressure measurement boreholes, during a water injection process in the same coal seam, the coal seam water injection pressure should be increased in a timely manner at the corresponding time nodes. The method of the present disclosure can effectively avoid the phenomenon of water flooding caused by excessive initial pressure during water injection.

Abstract: The present disclosure relates to code scanning methods based on vehicle-mounted cameras. One example method includes collecting a first image by using a vehicle-mounted camera, parsing a target encoding pattern included in the first image, and when no parsing information is obtained, collecting, based on image data obtained by the vehicle-mounted camera, another image that is close to the first image in a time relationship for parsing to attempt to obtain parsing information in the target encoding pattern.

Abstract: An information recording method includes obtaining image information; displaying prompt information on a head-up display based on the image information, where the prompt information is used to guide a user to record facial information; and obtaining the facial information.
