Mining Levels Stations Drifts amp Crosscuts

Mar 29 2017 Lateral Development. In tabular dipping lodes and thick massive deposits the ore bodies are developed laterally at several horizons spaced at more or less regular vertical intervals. In areas of high relief each horizon may be developed by driving an adit into the side of the hill from which branch headings are driven as required. When the main extraction opening is a shaft the horizons or levels are developed from stations cut into the side of the shaft.
