Mine waste rock piles pose an environmental hazard which is difficult to assess without an appropriate sampling procedure. A sampling strategy was devised for four waste rock piles representing different types of mineral deposits in the Hillsboro mining district in Sierra County, New Mexico to characterize their geochemistry.
The rock-waste pile named BF-04 fits in this context of contamination, and it was studied based on the Electrical Resistivity Tomography technique, inversion models and isosurface models
2021-3-23 · Spanish researchers are proposing an alternative technique for the rehabilitation of mine rock waste piles by classifying and selectively managing mine waste. In a study published in the Journal of...
The largest waste rock piles across the Schlema-Alberoda mining area will be left in place to be rehabilitated in situ. This involves regrading of the slopes. Finally, to reduce dust emanation, radiological exposure, and infiltration of precipitation,

2016-2-22 · Waste rock, which consists of rock and target minerals in concentrations too low for economic recovery, is removed along with the ore. Waste rock includes granular, broken rock that ranges from fine sand to large boulders, depending on the nature of the formation and mining methods employed.

Improved design to reduce contaminant mass loadings from waste rock piles is an increasingly important consideration. In certain cases, an engineered cover system containing a flow control layer (FCL) may be used to mitigate the release of metals out of a pile using capillary barrier effects (CBEs), diverting water away from reactive materials below.
Chapter Outlines. This book, Guidelines for Mine Waste Dump and Stockpile Design, is the third book in the LOP Guideline Series and focuses on the investigation, design, operation and monitoring of waste dumps, dragline spoils and stockpiles associated with large open pit mines.This book has been written by a consortium of geotechnical consultants and individuals
