Front bed volume of blast analysis and stability of a reduced volume measures

-30cm quartz veins, quartz veins and altered basalt at the junction, more dense pyrite particles can clearly see the small gold particles, and the upper and lower limits of disk access is obvious. ZK601 hole project is also one of the holes in 2003, has been proven in the vertical depth of 400-550m have been to the L27-8 probe pulse along the section in the 934 level, with the ZK602 hole,[link widoczny dla zalogowanych], the angle between the upper plate 50. , The next plate angle is 40. A 5O. Upper and lower limits for the gradual transition plate, upper and lower plate are chert, pyrite particles decreased, and then transition to basalt, sandwiched between the fracture zone and a thin layer of fault gouge, but the fracture zone and the lower plate angle compared Large, 80. So. 3 holes from the above analysis, L27-8 clock with more than 600m long, drooping from the surface to about 350-690m deep, with veins ranging from 50-100m thick, the disc slowly than the lower plate that are parallel, the East West steep relief , spur more. Parallel distribution of the veins, with veins pinch reproduction, pinch out the side now, swelling shrinkage, bending wave characteristics, and in the 934 level (400m) below the main ore body is gradually slowing down, the thickness gradually become larger (in 449-463m vertical depth range) trend. Accordingly expected in El5 line position, between the 450-470m to see L27-8 once again along the part of the vein, and vein in the L27-8 60-70m under the plate can be found at its offshoot - ( on the next 13) (2) make up the former bed temperature electrode placement. (3) are following procurement of the quality of coke, and coke screening and an appropriate increase in coke rate. (4) strict control of particle size, moisture content, the metering system to work effectively, as indicated in slag casting machine, turn the block casting slag, slag-slip materials to address to improve the block transfer rate. (5) Winter special high-grade ore production should be based. (6) reduce the material in the Mgo content. An offshoot of the Treaty 5-10m, ZK602 hole can be seen along this vein part,[link widoczny dla zalogowanych], ZK601 generous clock pulse can be seen this site (about 5 ~ 8l \consistent with the main seam in the rock, is expected to 500m vertical depth in the E15 line to see the veins along the section. According to characteristics of ore body, the veins may also extend the strike length to the next exploration line range. This is expected in the next hole (El5 line hole layout will be further confirmed). Data analysis from the underground and surface drill hole data analysis, the following conclusions: the area is the main quartz vein gold deposits - altered rock type gold deposits, the geological conditions are: (1) can not do without a favorable fault conditions; (2) inseparable from the quartz veins and silicified basalt; (3) can not do without sulfides. Accordingly, we can guide the underground mine exploration and surface drilling work, the more accurately predicted vein site, met: (1) with pyrite, arsenopyrite, silicification, carbonate alteration of other areas; (2) the main fault with the lateral junction of the low-order sub-fracture; (3) different parts of the complex structural systems; (4) gray, smoky gray quartz veins,[link widoczny dla zalogowanych], vein body with black, dark green stripes, a wall clock Juan mica alteration, etc.; (5), pyrite, arsenopyrite and other sulfide dense Department,[link widoczny dla zalogowanych], combination ore complex, fine mineral particles is relatively high gold content of rocks. In addition, we can also geophysical and geochemical data, looking for anomalies of gold, as gold prospecting, and the following two points with a sequence so you can look for concealed ore body as indirect signs: (1) North West to the veins axial zoning order bad U: Hg-W-Mo-Bi-As-Au-Sb; (2) I27 clock zoning sequence: Bi-Hg-As - w-Ag-Au-Mo.

(7) raise the low matte surface before the bed. High-low matte surface, so that slag layer thinning, to reduce the slag Mgo precipitation of the area, can effectively inhibit the reduction before bed, but once the walls of melt adhesion and improve the surface can not cause its melting, due to low matte temperature is low, at less than the melting temperature of refractory material.
