摘要
Areas exposed during the open cast mining, e.g. of salt and potash, are returned to an acceptable form by back filling with a mixture of the unusable spoil and industrial waste. The industrial waste is processed in a milling operation to produce a particle form that readily mixes with the mining waste. The combined mixture is subjected to compaction to project against ground subsidence. USE/ADVANTAGE - Use of industrial waste, e.g. from electronics industry. Returning open areas to original form.
