Title:
THREE-DIMENSIONAL SPACE DUST CONTROL AND REMOVAL METHOD USED FOR DUST PRODUCED DURING BRACKET MOTION OF FULLY MECHANIZED MINING FACE
Document Type and Number:
WIPO Patent Application WO/2020/006816
Kind Code:
A1
Abstract:
A three-dimensional space dust control and removal method for dust produced during bracket motion of a fully mechanized mining face. Different dust-proof measures are taken for upper, middle and lower spaces of the fully mechanized mining face; an air curtain machine (3) or different kinds of nozzles are utilized to form a gas-water double-curtain closed space or a single fog-filed closed space; a sensor transmits a signal to a central processing system, thereby conducting fully-automatic spraying dust-reduction in the bracket moving process of column descending, bracket advancing, column ascending and the like, and high-concentration dust is concentrated in the closed space to be treated in a concentrated mode, or the high-concentration dust is blocked outside of the closed space. A wireless transmission system is employed using closed dust-isolation and a spraying dust-reduction mode. A remote control device is utilized to transmit a radio signal, and a signal processor receives the signal and transmits the signal to a controller.
