The invention relates to a
simulation method and device for a hydraulic support column descending and support moving dust production migration rule, and belongs to the technical field of
coal mine
dust control. In order to solve the problems that the prediction error of an existing model exceeds 40%, the migration
path deviation exceeds 50%, the side seam adjusting precision of the device is + / -20 mm, and the dust falling efficiency fluctuates by 35%, a multi-factor
coupling modeling and intelligent dynamic regulation and control technology is provided. The method comprises the following steps: constructing a dust production prediction model of
coal rock
hardness,
water content, roof pressure bearing and side seam spacing
coupling, monitoring dust distribution in real time by adopting a
laser scattering sensor and a particle size
spectrometer array, designing a high-precision electric push rod to adjust the side seam spacing to + / -0.5 mm, and dynamically correcting an error in combination with Kalman filtering. The device comprises an adjustable support
assembly, a triaxial pressure loading module and an
intelligent verification system. The dust production prediction error is 9.8%, the migration deviation is 14.6%, the adjusting efficiency is improved by 3.2 times, the dust falling fluctuation is compressed to 7.9%, and the respiratory dust inhibition rate reaches 85.4%.
