【 摘 要 】

The composition, state and properties of the dispersed technogenic soils of the sludge collectors' dikes at the Baikal pulp and paper mill (BPPM) have been studied using standard and specific methods. As a result, a specific technogenic formation has been defined, i.e. clayey pulverescent sands. The sands have been studied for the first time, the study concerning the sands' chemical and microelement composition and the toxicant pollution degree. It has been found that the sands are potentially running, have low plasticity due to the joint influence of the clayey and pulverescent fractions, and a capacity for physical-chemical activity. The examined wells have practically no dangerous zones of fluid consistency.
