Management And Restoration Of Songxian Leimengou Mo Deposit Eological Environment Protection

To research the environmental problems caused by the Leimengou Mo deposit mining activities according to the "Regulations" mine geological environment protection, according to present situation of mining and mining design of the governance of the present and future mines or possibly existing environmental restoration.Songxian Leimengou Mo ore deposit is a medium sized open pit mine, annual production scale is 99×104t. Mine design for the open-pit mining, single highway development of automobile transportation. The gentle slope mining, stripping the steep slope of the stripping technology. Step height 12 m. Minimum mining elevation of 630 m, the highest stripping bench consists of 798 m, 822 m, 786 m, 774 m, 762 m, 750 m, 738 m, 726 M, 714 m, 702 m, 690 m, 678 m, 666 m, 654 m, 642 m, 630 m a total of 15 steps.According to the present situation of evaluation and forecast evaluation results, environmental protection and restoration of partition: open pit, 1# dump and 2# dump of emphasis prevention region(0.0347km2), road industrial sites and mining area as the second emphasis prevention area(27000m2), other regional general prevention area(0.1084km2). Good governance division of partition, layout management project in the area.Opencast stope layout warning signs, pit edge water drain, slope concrete spraying support engineering, pit backfill and vegetation restoration and platform of vegetation recovery engineering; dump layout warning signs, building water drain, slope and retaining walls and stone blocking dam and vegetation restoration in mining engineering; industrial site end after the removal of all industrial site building, in situ backfill soil, grass and trees; the layout of road signs, road cutting slope on both sides of the road planting reinforced concrete spraying support, Platycladus orientalis.Opencast stope layout warning signs, pit edge water drain, slope concrete spraying support engineering, pit backfill and vegetation restoration and platform of vegetation recovery engineering; dump layout warning signs, building water drain, slope and retaining walls and stone blocking dam and vegetation restoration in mining engineering; industrial site end after the removal of all industrial site building, in situ backfill soil, grass and trees; the layout of road signs, road cutting slope on both sides of the road planting reinforced concrete spraying support, Platycladus orientalis. Conclusion: the Songxian Leimengou Mo mine complex degree of geological environment is complex, the mine geological environment impact assessment level a.The mine is the important construction project; evaluation of geological environment condition is complicated, risk evaluation of geological disasters in the mine working level to level. The mine is the important construction project; evaluation of geological environment condition is complicated, risk evaluation of geological disasters in the mine working level to level. Restoration of the work by the mine environment, can effectively restore the mine environment was destroyed, the surface ecological can effectively restore, avoid or reduce the occurrence of geological disasters.
