Mineral material processing method and processing plant
In a mineral material processing method, mineral material is processed in a mineral material processing plant. Heat generated in heat sources of the processing plant and/or fuel used in a motor of the processing plant is cooled in a cooler of the processing plant. The cooler is equipped with a blower. Wetting water is directed to the mineral material for binding dust generated in the processing. Heat of at least one heat source of the processing plant and/or heat of the fuel is transferred to the wetting water before using the wetting water for dust binding. The wetting water is directed, before the dust binding, to a first heat exchanger for receiving heat in the wetting water.
SPRAYER FOR SETTLING DUST OF COAL MINE
A sprayer for settling dust of a coal mine includes: an outer housing, having at least one opening configured to spray water mist; a sprayer, placed in the outer housing, configured to spray water mist through the opening; a plurality of water curtain nozzles, configured to spray water curtain lines outside the opening to block suspended dust; and a support, configured to support the outer housing. The water curtain nozzles are in an equidistant arrangement around a center of the opening. A plurality of the water curtain nozzles are constructed such that the nozzles are all oriented toward the same point, to form a circular or conical water curtain.
Autonomous Dust Mitigation in Mining and Construction Applications
The autonomous dust mitigation m mmmg and construction applications system disclosed herein may comprise a system that automatically detects dust at mmmg and construction sites and dispatches dust mitigation equipment in response to such detections. The dust areas detected may be assigned priorities within the system, and may be addressed or ignored based on various parameters dictating the behavior of the system. If, for example, an area of dust is not currently in use by local equipment, the system may not dispatch equipment to address that area. If, on the other hand, an area of dust is affecting a high priority or high risk area of the site, the system may prioritize the dispatching of dust mitigation equipment to that area over other areas. The system described in the present invention comprises an autonomous dust mitigation system used in mining and construction applications that contains a plurality of sensors, a computing device, a dust area mapping system, a dust area prioritizing system, and a plurality of dust mitigation equipment.

Autonomous Truck Loading for Mining and Construction Applications
An autonomous truck loading system can have a database that stores a plurality of elementary behaviors for various phases of a process of loading the autonomous truck by the one or more loaders. The stored elementary behaviors can include predetermined maneuvers for the autonomous truck, sensing behaviors; and logic behaviors. An operator can select multiple ones of the stored behaviors via user interface. A controller can assemble the selected behaviors together into an operation script for loading of the autonomous truck by a loader. The controller can control the autonomous truck to perform the operation script.
Autonomous truck loading for mining and construction applications
The present invention encodes this knowledge into a database of preferred loading conditions and creates a set of automated maneuvers that accomplish the loading actions. The invention assumes that the truck has a drive-by-wire kit and that it is capable of moving under computer control. This invention provides a set of tools that allows for the automation of the loading process. The invention is relevant to situations where the truck is autonomous and the excavator is not, or when both are automated.

PLASTIC GEL MATERIAL FOR PREVENTING SPONTANEOUS COMBUSTION OF COAL
A plastic gel material for preventing spontaneous combustion of coal, including water, a crosslinking agent, a toughener, a coagulant, an aggregate and a water glass. The crosslinking agent (AlCit) is prepared by mixing a polyaluminum chloride solution and a citric acid solution then neutralizing the mixture with a sodium hydroxide solution. The coagulant is one or more of potassium bicarbonate, sodium bicarbonate, ammonium bicarbonate, sodium carbonate or glucono-δ-lactone (GDL). The toughener is one or more of pregelatinized starch, sodium alginate, carboxymethyl cellulose or polyacrylamide. The aggregate is coal ash or bentonite. The plastic gel has good water retention, toughness and inhibition performance, and helps avoid easy cracking and pulverization in inorganic silica gel consolidating bodies after losing water. The plastic gel can cover the surface of burning coal mass, reduce the temperature of the ignition source, heat radiation and production amount of CO, and have a fire extinguishing effect.
FLUID APPLICATION FOR AUTONOMOUS HAUL TRUCKS
A method for applying fluid to a travel lane is disclosed. The method may include receiving information related to a travel lane including a first set of tire paths and a second set of tire paths to be traveled by one or more vehicles, generating spray pattern control information for a fluid application machine having multiple spray heads based on the first set of tire paths and the second set of tire paths to be traveled by the one or more vehicles, and selectively triggering the multiple spray heads of the fluid application machine to alternately apply fluid to the first set of tire paths and the second set of tire paths based on the spray pattern control information and based on a current position of the fluid application machine on the travel lane.
