RESEARCH ON DEEP JOINTS AND LODE EXTENSION BASED ON DIGITAL BOREHOLE CAMERA TECHNOLOGY

Abstract

Structure characteristics of rock and orebody in deep borehole are obtained by borehole camera technology. By investigating on the joints and fissures in Shapinggou molybdenum mine, the dominant orientation of joint fissure in surrounding rock and orebody were statistically analyzed. Applying the theory of metallogeny and geostatistics, the relationship between joint fissure and lode’s extension direction is explored. The results indicate that joints in the orebody of ZK61borehole have only one dominant orientation SE126° 68°, however, the dominant orientations of joints in surrounding rock were SE118° 73°, SW225° 70° and SE122° 65°, NE79° 63°. Then a preliminary conclusion showed that the lode’s extension direction is specific and it is influenced by joints of surrounding rock. Results of other boreholes are generally agree well with the ZK61, suggesting the analysis reliably reflects the lode’s extension properties and the conclusion presents important references for deep ore prospecting.
