Abstract

To date, the total amount of rock mass displaced on the planet exceeds 100 billion tons. The result of such impact is the formation of man-made massifs - geological structures, composed of rocks or sediments of anthropogenic genesis, which differ in their composition (chemical, granulometric, bacteriological) and properties (physical, mechanical, filtration, sorption, etc.) from the host rocks. Shapes and sizes of man-made massifs are determined mainly by technological processes. In areas of sulfide-containing technogenic massifs, due to waste in an oxidizing environment, the formation of acidic drainage water occurs, the processes of formation of which are complex and nonstationary, which greatly complicates the monitoring of the state of the massifs. Development and application of a new method of acid-alkaline balance, consisting in determining and comparing the acid potential and neutralization potential, formed by rock or waste, allows with high expressiveness and accuracy to monitor the situation in areas of sulfide-bearing man-made massifs, significantly reduces the time for laboratory research.
