ბოლნისის პოლიმეტალურ საბადოზე ჭაბურღილების ბურღვის ტექნოლოგია და მოსალოდნელი საფრთხეები

Abstract

Geological-exploratory geophysical works carried out in the ore area of precious metals of Bolnisi district, detailed exploration of the deposit by drilling pillar wells are discussed. Well washes were produced using drilling fluids treated with CR-650 polymer powder. They performed the function of lubrication and cooling of drill guns. When removing the core, a removable core receiver was used without loading - removal operations. This method allows the core material to be removed as much as possible, quickly and without loss. Drilling of wells at the Bolnisi polymetallic belongs to dangerous business processes, therefore a number of labor safety requirements were taken into account at all stages of work performance. In the process of drilling wells, a high probability of mechanical and thermal injuries, vibration, noise and bad organization of the work is expected.
