Hazard Assessment And Research For Prevention Project On Slag Mudslide Debris Flow In Tongguan Gold Mine Area Of Daxicha

Da Xicha slag and the formation of landslides occurred, with the exception requires basic conditions (loose material to provide solid, full of water, topography, and other three elements), the human factor is also very important priming conditions. Slag of the landslides occurred due to the development of mineral resources in the course of the slag stacking unreasonable and do not pay attention to ecological protection, water power in certain circumstances, lead slag heap move or slip, landslide and mud-rock flow of the phenomenon.This paper in the field of geological prospecting and indoor Based on the analysis of data through field investigation mudslides disaster points of the terrain, geological structure, and then combine the indoor geological conditions, weather conditions analysis showed that the mud-rock flow have Da Xicha these conditions is mutual The result. A simple analysis of the gold mine clearance area Da Xicha slag of debris flow in the development of reasons, character, and preliminary identify its unique characteristics.Assessment of risk of landslides is in danger of division on the basis of the. In this paper, the level of methods, given Da Xicha debris flow risk classification and assignment of standards, the establishment of mine slag debris flow risk evaluation system-level model (forthcoming issue of divided into different elements of the composition, and in accordance with the elements And the interaction between the various factors will be attached to relations between the different levels in accordance with the composition together to form a multi-level analysis of the structural model, the lowest level and the highest level of the relative importance of the relative merits of the order or out). Then, from the slag and mud-rock flow and stimulate attributes of the human form of debris flow in the hazard, environmental conditions to determine the degree of risk of debris flow. Determine risk of landslides areâ…¢level, is a moderate risk, and the basic line with the results of field investigations.Based on the evaluation results, were set up to the gutter, retaining walls and other measures of a debris flow management.
