Environmental Pressure Of Mineral Resources Development

The influence of the large-scale development of mineral resources to human is unparalleled in the past times. Negative effects arising from unreasonable usage of mineral resources is regarded as the common phenomena in all over the wold. Research on the serious environmental issues of the mineral resources development has become the principal problem of sustainable development and utilization of mineral resources. Quantization analysis the regional environmental pressure has also become a key technical question.Therefor, this paper constructs the indicator systems of quantization analysis the regional environmental pressure based on the theory of ecological foorprint and analyzed in very great detail the theory of measuring the regional environmental pressure. Eeological footprint being a tool of sustainable development decision-making is one of populized methods to assement sustainability in the recent. On this basis, the Nanfen open-pit was investigated and studied the natural ecological and economic system situation. The yearly situation of 1995-2007 were studied using its practice production data based on the theories of econmies, systamaties and ecological economic in quantitive and qualitive, dynamic and static. The results showed that:The indicator of the ecological footprint demand is a tool of measurement to human consumption on the ecological resources and the impact on the ecological environment. The per capita ecological footprint is the ascendant trend that over the years from 1995 to 2007 in Nanfen open-pit.The ecological deficit of Nanfen open-pit increases almost 50.85%. Ecological rucksacks indicator measures the material consumption intensity and intensity during the process of developing the mineral resources. Ecological rucksacks indicator of Nanfen open-pit reached a maximum value of 6.26t in 2006 which is is 2.1 times of 1995 during the study period. It is shows that the final mining area and the striping ratio as a decisive role determine the ecological rucksacks of open-pit that the largest component of ecological rucksacks is stripping rock. Judging from the eco-economic system indicator of Nanfen openpit from 1995 to 2007, the ecological footprint index represents the remained capacity for the future sustainable development. The ecological footprint index is less than-100%. The ecological deficit per ore production reflects the economic integration effect of human social economic activities. The ecological deficit per ore production shows property of fluctuations changes, the fluctuation range is 0.01 hm·t-1, the ecological footprint diversity index varied between 0.57～0.82. The Results indicated that the variety of resource consumption was becoming more balanced, and the ecological sustainability of mine has been improved.
