Kilometers of the reclamation of tailings method
Reservoir construction of housing units more than 20 months, building covers an area of more than 30 million m, and the construction of standard gauge railway, which husband-scale buildings are city hall and colored Yi Yu Xiao-body Museum of the company closed library 3.1.1 tailings after the 5 - way geology tailings parts: the upper Niger mining database granules rent, water content less. Tailings consolidation + and have some basic commitments cutting capacity. By the end of the lower part of the library, a high water table, showing plastic flow state. Library-based part of the bank to F can be divided into several layers of strata. Quaternary Holocene Lake Sediments and alluvial soil, gravel layer, and Moraine Lake Sediments have repeatedly silty clay and loam, bedding clear, soft soil, compression of large, plastic state was soft to the flow, engineering geology poor. Alluvium with clay loam and loam with gravel, clay and loam with black spots or ancient ferromanganese quality iron-manganese nodules material was wet, hard plastic, revolves around the state sub-soil of ancient stone, clay was soft plastic-like sub- , aggregates composed of limestone, sandstone, was sub-angular, gravel content of about 40. Engineering geology in general. Dan Zhancheng eggs into quartz sandstone, sandstone, rounded desolate better. Was in the secret state. Engineering geology better, but the distribution is limited in scope. Uneven distribution of these layers thick. Typically a few centimeters to several meters. Moraine layer consists of rock, gravel, sand and soil clutter piled Brighter Summer Day, distributed unevenly. Generally less visible in the surface 17m tailings 3.1.2 closed libraries to the library building time the mine closed Niger library is from the southeast to the northwest point of Yin carried out. General Library closed after 3 to 5 years to build housing in the reservoir area. Housing is generally highly】 9gd years ago, 3 to 4 repeated. Since 1995, the construction of six houses in the southeastern part of the reservoir area is generally 5 layers. With the gradual consolidation of Nepal with mine, foundation strength and continuous improvement in building a more intense land use, possible future development to a higher development. 3.1.3 Technical measures to build a house in the tailings repository where God used to copy processing methods and technologies must be based on soil engineering, water 60 l Mountain Mine Metallurgical Design and Construction 5, 1995 article geological conditions, the upper loading and delivery methods, the use of building materials and the environmental impact of various factors were analyzed. Through technical and economic comparison before OK. Houses built in the database used in the form of ground treatment methods and different basis, the types are precast concrete pile foundation, pile foundation stone, sand mat foundation and concrete rubble and other large base. A frame structure, bent, brick, etc. These built structures anywhere from a few years after, as many as ten years of tests and found no abnormalities. Need attention is the consolidation of the tailings is not well under certain conditions, the drum bearing has a certain capacity. However reasonable produce earthquakes of magnitude 7 or above will significantly reduce liquefaction carrying capacity. However, coarse particles of the tailings, drainage conditions are better, less thickness of the accumulation, over time. The gradual consolidation of Nepal Mine, increasing density, carrying capacity will be improved. Mu liquefaction potential will become increasingly smaller. 3.2 Agriculture, forestry and other land reclamation in a building, structure covering the reservoir area, in addition to roads, paving venue. Other venues are in the casing after the flowers and different kinds of trees planted. Main tree species are holly, aspen, camphor, Indus, willow, fir, acacia, etc. more than ten kinds, the growth of normal. Species of the southwest side of the library has a variety of vegetables, such as the East melon, pumpkin, beans, vegetables and so on. Grew well northeast of the library, a building sketch, tree-lined trails and middle of the street parks and other facilities. Kilometer tailings reservoir construction and Pat Green cover up 94kin. . Reclaimed area of the reservoir area by the total area of 90, and the remaining sludge 15kin area about Pat as the \Tailings residents, workers, businessmen and students nearly two million people. Over the past tailings beach. Today, trees, flowers and lush, a variety of building scales tablets crowded. However, as if mixed with the urban one (see Figure 2). Prince Yu 2 km flat tailings reclamation tailings Kids in 4 Conclusion 4.1 is a huge source plane to the wind as the medium of harmful and toxic elements in the homes of any of its dust released into the atmosphere, pollute nearby environment, destroying the ecological balance of 42 re- Reclamation work to follow the progressive Pavilion, reclamation in the form to local conditions, under different circumstances, to take forestry reclamation, agricultural reclamation, building rehabilitation, so that the operator sets the development of the surrounding environment. 4.3 when the building rehabilitation is the key foundation treatment, according to the tailings properties, structure formation, such as design appropriate junction village form the basis for structural design and to take credible measures to achieve security, economic, and rational purpose. 4.4 Results table urban planning, according to location, environmental conditions such as Bu Zhi Jian different functions, structures and a variety of rehabilitation methods in order to able to receive better social, economic and environmental benefits. Received 1995-5 a】 1 (revised return) About Yangwan Fu. Design and Research Engineer boiler colored hills.
