The last reported copper production was eighteen tons in 1952, valued at $8,712. Most of the ore came from the Old Hazel Mine in Culberson County. During the mid 1950s, however, most of the Texas copper mines were inoperative. Large deposits of ore exist in North Texas but have not been developed because of their low metal content.

Open Pit Mining

There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8). Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface.

Resistivity

The electrical conductivity of Earth''s materials varies over many orders of magnitude. It depends upon many factors, including: rock type, porosity, connectivity of pores, nature of the fluid, and metallic content of the solid matrix. A very rough indication of the range of conductivity for rocks and minerals is in the following figure. Figure 2.
