A typical negative impact on water resources for mining companies engaged in blasting operations is the discharge of quarry and mine water contaminated with nitrogen compounds. The solution of the problem under consideration is assumed with an integrated approach based on the use of partially flooded abandoned mine workings already available at the enterprise as bioengineered structures. The article substantiates and confirms the possibility of using flooded abandoned open-pit mine workings for the treatment of wastewater from mines and quarries contaminated with nitrogen compounds from the most environmentally hazardous components by natural microbiological nitrification. The advantages and disadvantages of the applied cleaning methods are investigated. The possibility of applying the method of biological purification based on the use of flooded waste workings with the existing natural ecosystem is justified from the point of view of economic efficiency. The advantages of this method are described and the effectiveness of its application is confirmed.
