摘要
FIELD: mining. SUBSTANCE: method includes frame, hydraulic excavator with nozzles, water supplying pipeline, plug deleting taps, washing out of rock pile by hydraulic excavators, carrying pulp and determining parameters of the washing out. Indicator is installed in rock pile to determine tixotropic strengthening of rock pile during its lying. Then in the process of washing out rock particles are taken through screens with size of openings equal to dmax and dmin used to determine quality of washing out in yield of fractions using formula: , where Vmax is total volume of washed rock yield; Vmin is yield of rock converted to pulp; dmax and dmin are sizes of pass openings in screens; K is indicator of uniformity of washing out, in so doing decrement specifying concentration of rock particles converted to pulp in the process of washing out in each time moment is determined using formula as follows: , so where va and vt are average and instant speed of washing out; γ1 and γ2 are decremented concentrations of rock particles in pulp in the process of washing out; t1 and t2 are time intervals concentration increase occurs for. EFFECT: increased accuracy.
