Research On The Opencast Mine-geological Environment Problems Of Wutai Tianhe Bauxite

Mining caused a series of mine geological environment problems, such as collapse, landslide, debris flow, damage of land resources, etc, which cause serious damage to human survival environment, the mine geological environment problem is a major product of human activity, is predictable and preventable. through analysis and study of mine geological environment problems, can reduce the influence of mining on the environment and destruction, to realize the coordinated development of resources and environment.This thesis in Wutai Tianhe bauxite for the study, the main use of site visits and field surveys, document data collection methods, consult the relevant norms and other methods, Research mainly on the type of mine geological environment, distribution, size, causes, and other harmful levels and predisposing factors were studied. The main work and results are as follows:1. The field investigation of Wutai Tianhe bauxite mining area of natural geography, stratum lithology and geological structure, hydrogeological conditions, engineering geological conditions, geological characteristics of ore bodies and surrounding other human engineering activities.2. Under current conditions study, the presence of mine geological environment, there are collapses, landslides, mudslides, destruction of land resources, topography landscape damage and other issues.3. Collapse, landslide problem: land leveling and construction of roads rming slope instability, as rock weathering, joint fissure development, structure, crushing, free surface development, under the condition of rainfall, weathering, vibration and so on, will cause the collapse, landslide disaster, and the six existing slope analyzed from the position, size, slope, lithology, and threaten the stability of the object; Only in open-pit mining slope soft rock breakage ocation or joint fracture location, local structure small collapse and landslide geological disasters will happen; dump Because of loosely packed, Under the impact of mining rainfall and prone to collapse slippery.4. Mudslides problem: mining valleys are well developed, was "V" shaped,G1,G2 and G3 valleys of the source is mainly formed by natural collapse and slide excavation loose debris, flood during the rainy season is scary ups, prone to debris flow, to quantify the 15 factors of degree of prone to give different gully mud for evaluation.5. Open-pit mining, since the surface were directly destroy the original topography, open pit, waste dump, industrial sites, road construction in the process of occupation of land, the construction process to take the spoil, surface excavation and other construction activities, causing serious land damage. Excavation of mine has also led to aquifer damage problems.6. For major problems, propose appropriate measures to restore.
