    Strip mining. Strip mining as the name describes is a process of removing rock and soil in strips to get to the valuable mineral ores below.After miners extract the resources they put back the leftover rock and soil called mining spoils or tailings to fill in the hole.. One way to replace tailings is to simply dump them luckily U.S. regulations require mining companies to replace
