Abstract
A gas-liquid spray dust settlement system for a fully mechanized mining face includes an atomization humidification subsystem, a boundary mist curtain subsystem, and a dust mist recycling subsystem that are all arranged outside the fully mechanized mining face, where the boundary mist curtain subsystem includes high-pressure blade nozzles mounted to hydraulic supports. The atomization humidification subsystem includes a spray dust settler mounted to a rocker arm of a coal cutter and configured to spray water mist completely covering the high-pressure blade nozzle. The dust mist recycling subsystem includes a wind-water linkage dust remover mounted to a semi-encircling support base, arranged under the spray dust settler, and configured to collect the water mist sprayed by the spray dust settler.
