Chemical Composition of Waters on the Pavlovsky Coal Quarry (Far East Russia) and Surrounding Areas

摘要

The open exploration of the Pavlovsky coal deposit which is one of the biggest in the Primorsky region (Far East Russia), has contributed to some pollution of the ground, surface, and underground waters on the Pavlovsky Coal Quarry (Far East Russia) and Surrounding Areas. Based on the analysis of the available hydrogeochemical data on the Pavlovsky deposit. These date include the turbidity which is in three sites of the lake (toward the exit to the river) varied insignificantly - 15.9-16.8-13.1 mg/L., Main ions and organic matter consist of Sulphate, Chlorine, dissolved nitrogen, dissolved phosphorus, Microelements.(- Zn and Cu-), Aluminum, strontium, lithium, Boron, Chrome, Iron, manganese. From these date we drawn conclusions that the action of the coal quarry is still less to the drainage system of the Razdolnaya River. The main ecological problem connected with the coal mining in this district is a significant drop of the underground water level because of the pumping-out and disturbance of the natural flow of the supra-coal water-bearing horizon resulting in mixing of waters of different composition and change of chemical composition of water-bearing horizon. This may effects not only the Abramovka River waters, located in the immediate vicinity, but the removed objects also including Khanka Lake, when underground water discharged onto the lake floor.
