[Abstract]:With the increasing demands of social and economic development, the engineering and technical system of the mine is also progressing and improving. The exploitation of resources is developing to the deep, the geological conditions are deteriorating, the broken rock mass is increasing, the in-situ stress is increasing, and the inflow of water is increasing. It has brought about a series of problems such as deep ground pressure, deterioration of operating environment, rapid increase of ventilation and production cost, etc., which has restrained the increase of production capacity and the full recovery of mineral resources. Therefore, we should increase the strength of scientific and technological innovation, solve the key technical problems of deep mining, adopt advanced technology and equipment, and reduce the safety risks brought by deep resource mining. It is of great significance to provide a scientific and technical approach for safe, economical and efficient exploitation of deep resources. In this paper, the selection of mining scheme for 30-14 orebody with deep water-bearing breakage below the middle section of Daqing 1360 in Yunxi Songshujiao Tin Mine is the main research content, on the basis of summing up and analyzing the development status of relevant theories and technologies at home and abroad. The following research work has been carried out: 1, to carry out regional hydrogeological investigation and analysis, to establish regional hydrological models, to reasonably predict the variation of water inflow in the course of ore body mining, to formulate the water gushing treatment measures and to seriously analyze the mining technical conditions of ore bodies, Through the comparison of many schemes, the reasonable mining method is selected, and the technical links such as cutting engineering arrangement, rock drilling blasting, filling and so on are studied, and the results of the research are tested in industry. Practical techniques have been developed to solve the key problems of mining scheme selection, engineering layout, mining, filling, construction organization and management of deep water-bearing broken orebodies. The research process of this paper is to combine the engineering practice problem, take the theory analysis as the instruction, in the engineering construction unceasingly summarizes, the research process, the design scheme has obtained the confirmation in the 30-14 orebody mining, and has carried on the consummation in the construction. The results are safe, reliable, efficient and easy to popularize. They are very representative and suitable for mining difficult mining bodies with deep contact zone, loose broken ore rock and complicated shape change of orebody. Is suitable for Gejiu East District deep resources development and utilization of the complete construction technology.
