Compania Minera Poderosa SA He has been conducting operations in the ore deposits in the RA2120 section of 4.5 x 4.5 m in Nv. 2120 San Francisco Lode mine Pataz. Reservoir characteristics are irregular, being unstable areas, qualifying as rock MF / P (much fractured poor soil), generating sobrerotura and damage to the crown, and increase the percentage of dilution. The operation is carried out in a conventional manner and are checked overconsumption of explosives, which is reflected in the so-called load factor indicator. Other deficiencies relate to blasting explosive improper drill column instead of 66 % were carried more than 75 %, resulting on excavations and increased the cost of drilling and blasting. In drilling deviations in parallelism they are detected by the absence of guiding , taking the burden no uniform remains and becomes larger at the bottom of the bore , affecting the fracturing and expected progress , especially if the holes relief are shorter that production . Faced with this problem you had as a result unfavorable indicators such as: advance 1, 66 m / disp.; yield 0.49 m / hg.; load factor of 31.79 kg / m drilling and blasting costs at 311.65 US $ / m . To solve these problems a scheme research considered increasing the length drill 6 to 8 feet and applying controlled blasting using non-electric delay was designed accessories. As a result the following objectives were achieved: the progress increased from 1.66 to 2.05 m / disp .; the yield increased from 0.49 to 0.71 ; The so-called load factor decreased from 31.79 to 26.1 kg / m and decreased the cost of drilling and blasting of US $ 311.65 to US $ 288.32 .
