Recultivation of disturbed lands is very important task of science and practice at large territories of mining in Siberia as in other regions of Russia and other countries. Condition of physical properties of new-formed soils technozems (Technosols) is one of key questions for future state and usage of these lands. Changes of technozem's physical properties over time as part of land restoration and reclamation at Nazarovsky brown coal mine wastes (Eastern Siberia) were studied at one, three, ten and twenty years after the beginning of reclamation. Technozems here are artificially formed soil-like formations, which were made by the method of filling a material of fertile soil layer (fertile soil material or FSM) on the leveled surface of technogenic deposits. In the process of keeping of FSM and mechanical formation of technozems, there was a marked deterioration of the physical state of the FSM. In order to restore physical properties of FSM, perennial herbs were sown on recultivated areas. Studies of physical properties at different age sites have shown that at the meliorative stage they are gradually restored by climatic, biological and pedogenic factors. Exposure to perennial herbs contributes to soil structure formation and reduction of compounding density. In case of prolonged (10–20 years) meliorative action physical properties are restored to norm of soils which are widespread in this geographical zone. However, the sharp interface between FSM and technogenic material remains, which can have a negative impact on the water regime of recultivated soils. In order to accelerate formation of optimal physical conditions in technozems it is necessary to carry out deep, irrevocable loosening, which contributes to reduction of density of both bulk layer and underlying technogenic rock. Some physical properties (bulk density, porosity) were gradually improving over time reaching Haplic Chernozems levels at the reference site.

与俄罗斯和其他国家的其他地区一样，在西伯利亚的大片采矿区，重新开垦受干扰的土地是一项非常重要的科学和实践任务。新形成土壤技术土壤（Technosols）的物理性质状况是这些土地未来状态和使用的关键问题之一。在开垦开始后的一年、三年、十年和二十年，研究了作为 Nazarovsky 褐煤矿废物（东西伯利亚）土地恢复和复垦的一部分的 technozem 物理特性随时间的变化。这里的技术土壤是人工形成的类似土壤的地层，它是通过在技术沉积物的平整表面上填充肥沃土壤层（肥沃土壤材料或 FSM）的方法制成的。在保持 FSM 和技术土壤机械形成的过程中，FSM 的物理状态明显恶化。为了恢复 FSM 的物理特性，在复垦区种植多年生草本植物。不同年龄地点的物理性质研究表明，在改善阶段，它们在气候、生物和成土因素的作用下逐渐恢复。接触多年生草本植物有助于土壤结构的形成和复合密度的降低。在长期（10-20 年）改良作用的情况下，物理特性恢复到该地理区域中普遍存在的土壤标准。然而，FSM 和技术材料之间的尖锐界面仍然存在，这可能对复垦土壤的水分状况产生负面影响。为了加速技术土壤中最佳物理条件的形成，有必要进行深入、不可逆转的松动，这有助于降低体层和下伏技术岩的密度。一些物理特性（体积密度、孔隙率）随着时间的推移逐渐改善，达到参考地点的 Haplic Chernozems 水平。
