METHOD OF STRESSED-DEFORMED STATE CONTROL OF ROCKS

摘要

FIELD: mining. ^ SUBSTANCE: equispaced low background chambers, consisting of layers of metals and/or liquid, absorbing external natural radioactive radiation, are placed on the earth surface. The residual gamma background is continuously measured inside the above chambers. Daily anomalies are separated in obtained variations of the gamma background by the method of Fourier analysis. Daily average anomalies of the gamma background are analysed if daily anomalies are available. When gamma background is raised more than 3â and according to field displacement of the increased gamma background there is judgment of the place of change of stressed-deformed state of rocks for the nearest 1-9 days. ^ EFFECT: extension of functional capabilities. ^ 2 dwg
