The Research Of Huanren Copper Zinc Ore Windlass Underground Cavity Analysis And Evaluation On Stability And Support Measures

Mineral resources because of its in the present as the main energy resources and industrial raw materials are used by people, Corresponding to the exploitation of mineral resources is more and more widely. With the development and utilization of mineral resources, Mine tunnel and other underground chamber safety literature in the mining process is now thepeople concerned,therefore, For evaluating the stability of chamber surroundingrock and post evaluation for unstable surrounding rock take supporting measures also formed a discipline, Is applied to mine roadway underground chamber. Huanren copper zinc ore deposit belongs to the typical comprehensive mineral,rich variety of nonferrous metals:copper,silver,lead,lron,zinc,molybdenum.7#xiangyang mine is a promote shaft, Deposit type belongs to the intrusion diorite and sedimentary limestone formed by contact metasomatism skarn type deposit typical. The proposed7#xiangyang windlass underground cavity,1989construction work surface of original rocks due to poor stability caused the top rock fall discand waste, In order to re-use, need to analyze the stability of windlass underground cavity, According to the results of stability analysis, take the appropriate support measures. Firstto hoist room of data collection, field engineering geological investigation, measurement,monitoring, sampling and analysis, According to the actualsituation, the collection and study of research situation related to this project at home and abroad, combined with the actual situation of the project, the classification method of qualitative analysis and quantitative analysis are combined to determine the country rock of underground cavity and country rock broken zone range of. Range of broken zone judged using the wave velocity test method to determine the scope of the field, Combinedwith the Platts theory, It is a kind of method to the theory calculation of the l broken zone, The synthesis of two determination results, The rangeof the broken zone ultimately decide the windlass underground cavity. Classification of country rock is the test data of physical and mechanical prop erties of rocks to make indoor test as the basis, combined with the related classification standardization of, Vertical displacement monitoring points onthe chamber surface, and record the relevant data, by the broken zone, rock mass classification, monitoring data, to research of Huanren copper zinc ore windlass underground cavity analysis and evaluation on stability. According to the results of stability analysis, Recommend the use of anchor spraying method combined with the supporting of Fissure Grouting. Through specific calculation, determine the type, length, fracture grouting way, injection processand injection thickness of concrete by using, Anchor becauseof its relatively low cost, simple construction process, wide applicability, and is widely used in tunnels, mines, slope, foundation pit, bridge engineering, its various area sthroughout the civil and mining engineering, At homeand abroad more than600kinds of anchorage technology. This paper discusses the method of each stage are used in qualitative analysis and quantitative analysis, the actual amount of reference and theoretical research methods of domestic and foreign advanced, perfect testing technology, the objective of the Huanren copper zinc ore windlass underground cavity analysis and evaluation on stability.couplet Huanren copper zinc ore windlassunderground cavity later supporting construction provides methods and parameters of advice.
