Study On Mining Technology Of Broken And Water - Rich Complex Orebody

Along with the social and economic development needs of the growing, the mine engineering and technical system has also been improved and perfected,resource exploitation to the deep development. With the increasing of mining depth, the deterioration of the geological conditions. The increasing of broken rock, stress increases, water inflow increase, brought deep burst, deteriorating operating environment, ventilation and production cost of sharp increase a series of problems, inhibited the full recovery of production capability and mineral resources.Therefore, increase scientific and technological innovation to solve the deep mining key technical problems, the use of advanced technology and equipment, reduce the risk of deep resource exploitation. To provide scientific and technical way of deep resources security, economy and high efficiency, which is of great significance.This paper to Yunnan Tin Songshujiao tin big Jing 1360 below the middle of the deep water broken 30-14 orebody mining scheme selection for the main research content in the summary analysis of domestic and foreign related theory and technology development status of foundation, carried out the following research work:1. To carry out regional hydrogeological investigation and analysis, the establishment of regional hydrological model, reasonable prediction of orebody in the process of mining Chung water changes, formulate measures for treatment of gushing water;2.A careful analysis of the mining technological conditions of the ore body, through comparison, select the reasonable mining method, and cut mining engineering layout, drilling and blasting, filling and other technical aspects were studied;3.The research results of the industrial test, forming a solution to the deep cut ore body mining scheme selection, engineering layout and mining, filling, construction organization management and other key issues of practical technology.The research process is combined with engineering practice and theoretical analysis as a guide, constantly sum up the construction, process research,scheme design in 30-14 orebody mining has been verified, and in the construction of perfect. The result of the formation is safe, reliable, efficient and easy to spread. It has a strong representation. It is suitable for the mining of sulfide ores in the deep contact zone, the ore body is loose and broken. The ore body is suitable for the development and utilization of the deep resources.
