METHOD OF CONTROL OVER STRESSED STATE OF SEISMIC REGION

mining industry, removal of stressed state over territories having plants producing soda and potash fertilizers. SUBSTANCE: liquid is pumped into deep water-bearing horizons. Excessive brines of potash production and chlorine-calcium sewage of soda production specially prepared and separated from suspended solid phase are used as pumped liquid. Value of seam pressure is measured after start of pumping. Underground tremors are recorded, pressure on well-head is being reduced after their appearance till tremors stop. Then pressure on well-head is raised again till tremors start and so on. EFFECT: enhanced functionality of wells by their usage for utilization of industrial sewage.
