METHOD OF DETERMINING NON-UNIFORM POWER PRODUCED BY THE RATIO OF BODY DISPLACEMENT FORCE TO SPECIFIC FLOW RATE OF FLUID MEDIUM Russian patent published in 2016 - IPC E21F1/02 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used for determination of body displacement uneven power. According to the method, the body is installed into the inlet section of mine working, body weight is measured, stationary air medium is installed at the production, providing possibility of movement along heading to the body, its length is measured, body midship section is measured, body movement time is calculated, preset medium movement speed is calculated relative to the body, preset force is determined and the maximum deviations from their magnitudes are calculated, at the presence of deviations their corresponding values are set in the heading exit area, body force and medium movement speed relative to the body are measured and specific density of medium volumetric flow rate is determined. Then force and specific density of volumetric flow rate are calculated in the heading exit area at each measurement. After that, force change modes values, specific density of medium volumetric flow rate are determined, value of initial power is calculated and the non-uniform capacity of moving body is determined in the heading exit area at variable force, variable specific density of medium volumetric flow rate, different modes of their change are calculated by given formulas.

EFFECT: technical result consists in measurement accuracy improvement of non-uniform power, produced by ratio of force to the specific density of fluid medium volumetric flow rate, and increase in reliability of the air fed into generation.
