The invention discloses a mining active magnetic water dust-
settling method and
system. The method comprises processes as follows: an
active agent suction
pipe extracts a surface
active agent from an
active agent adding
barrel, and the surface active agent and water in static pressure
water supply pipe are mixed uniformly in a mixer; formed active water flows in a Z-shaped magnetic channel of a magnetizer and is magnetized; and magnetized active magnetic water is transported to a
coal cutter spray
system, a combined mining supporting spray
system and a transferring point spray system for spray dust settlement. The system comprises the active agent adding
barrel, the static pressure
water supply pipe, the mixer, the magnetizer, the
coal cutter spray system, the combined mining supporting spray system, the transferring point spray system, the active agent suction pipe, a
branch pipe, a valve I, a pneumatic liquid driving pump, a flowmeter I, a
check valve, a valve II and a flowmeter II, wherein multiple groups of blocking plates are arranged in the mixer, and the Z-shaped magnetic channel is arranged in the magnetizer. According to the system and the method, the mounting is convenient, the structure is simple, continuous
magnetization can be realized, and the dust-
settling effect is good.
