Transformation of the Physical Properties of the Soils of the Industrial Area of Coal-Burning Power Station “Partizanskaya”

Abstract

Power stations provide a huge influence on the environment. This influence can be diverse and integrated: (1) land avulsion, (2) dusting from the open storage spaces of fuel, ash and slags, (3) huge amounts of ash-slug wastes containing toxic metals. The aim of the research is to evaluate the effect of ash-slug wastes of the coal-burning power station (CBPS) Partizanskaya on the ecological state of soils. Transformation of the physical properties of the soils appears in the increasing fraction of coarse grain size, reducing of the sludge content in the soils, which lowers the surface area of the soils and their sorption properties. Ash particles input to the surface of soil leads to the decrease in their antierosion properties. Water capacity properties of the soils are reduced and with the moisture up to 50% soils can flow. The obtained information about the properties of the abiotic components of the industrial area of the CBPS Partizanskayaash-slags, soils are the first step in studying the environmental situation in this area. One of the possible solutions aimed to improve the environmental situation in the industrial area of the CBPS Partizanskaya is recultivation of the ash dump and development of the technologies for the usage of the ash in the household economy.

Analysis and Assessment of the Environment in the Area of Abandoned Coal Mines in Primorsky Region

“…Generalization and systematization of the data in the literature shows that for the Far Eastern science and practice, the problem of assessing the the environment within the boundaries of abandoned coal mines is absolutely new. There are only some research experiences in this area [10,11]. It is known that [10,11] the negative impact of mining industry on the environment is manifested in the formation of numerous pits, adits, the bulk waste heaps, as well as mineral processing waste -the "tails" in the tailings stored in huge quantities, becoming a powerful source of pollution throughout the ecosphere for the tens or hundreds of years.…”

In the Far Eastern Federal District there is no enough development of the principles for the evaluation of ecosystem changes in the area of influence and creating a mining and environmental monitoring.…”
