Justification Complex Purification Technology Open-pit Mines Wastewater

Abstract

In 2012 the total volume of coal mining in the Kuzbass was about 200 million tons, including 116 million tons (60.3%) produced on open way, Fig.1. In 2013, it was produced 203 million tons of coal. In addition, there is no reason to believe that in the near future volume of coal will declines. Accordingly, the volume of wastewater discharged by enterprises will increase. So, from 2006 to 2009, there was an increase of polluted water discharge coal mines from 217 to 245 million m 3. Therefore, the problem of water pollution mines governmental waters and career is very important. Despite its advantages, open coal mining does more than the damage to the

Adaptive Technology of Using Backhoes for Full Coal Extraction

“…So the height of layer set in projects of 5 m, does not match conditions of extracting bedded coal seams with dip angle up to 30 degrees (in average 3.5 m). Nevertheless, the share of bedded coal seams in Kuzbass coal deposits is estimated as 20-25% [12][13][14][15][16].…”

Conditions for Minimum Dynamic Loading of Multi-brake Hoists

“…They are used in all sectors of the mining industry -both underground [11,12] and in open cast [13] mining, also it's an important element of the work safety [14,15].…”

Considering Behind Limit Deformation for Calculation of Coal Pillars Parameters by Finite Element Method

“…At the present time, the complex of the most pressing issues that mining science faces now, such as development of mechanization of coal mining [8,9], reducing aggressive impact of mining operations on the environment [10][11][12][13][14], design of organizational forms of coal enterprising [15][16][17][18], is supplemented with the problem of providing a world-class safety. Its main direction is researching the physical processes of coal extraction [19][20][21].…”
